! Danger

US carriers charge $10/day or $2.05/MB for data roaming in Uruguay. A single week of casual phone use costs $70–200+.

&check; Solution

A travel eSIM from Airalo connects to Claro's 4G LTE network at $2.74/GB. Same towers, same coverage, no roaming middleman.

How to avoid roaming charges in Uruguay

Your phone syncs email and iCloud in the UYT (UTC-3) timezone while you sleep. AT&T charges $10 for that idle night. Background app refresh, photo uploads, and system updates consume 1.5 GB per day without you touching the screen. Over 7 nights in Uruguay, those silent syncs cost $70 on Antel's network through AT&T roaming.

Disable data roaming on your home SIM before bed on day one — or better, before you board. Install a Uruguay eSIM that covers 20GB for $54.80. Set it as your data line after landing. Background syncs run through the eSIM at local rates. Your home SIM stays active for calls and texts over WiFi.

Carrier roaming costs revealed for Uruguay

Google Maps downloads 5 MB per minute of active navigation. A 20-minute taxi ride from the airport to your hotel burns 100 MB. At $2.05/MB on Antel, that one ride costs $205 in roaming data — more than most taxi fares in Uruguay. Turn-by-turn directions for a full day of sightseeing consume 300-500 MB, hitting $615-$1,025 without a plan. Over 7 days of navigation, per-MB charges reach $22. A 20GB eSIM on Antel covers all your Maps usage for $54.80. Download offline maps as a backup.

What roaming costs per trip day in Uruguay

Two travelers in Uruguay for 7 days: AT&T charges $140. Verizon TravelPass: same $140. Both phones connect to Antel independently — two daily charges, two midnight resets, two bills. Two eSIMs on Antel cost $109.60 total for 20GB each. Couple savings: $30.40. Date nights get expensive when every photo upload triggers a separate $10 charge on each partner's phone. The eSIM approach costs $109.60 for both travelers for the entire trip.

Per-day roaming fees for Uruguay

AT&T International Day Pass charges $10/day in Uruguay. Verizon TravelPass charges $10/day. Both connect through Antel and offer the same coverage map. T-Mobile includes international data on most plans, but throttles speeds to 256 Kbps — slow enough that Google Maps tiles fail to load and ride-hailing apps time out. All three carriers use Antel's towers in Uruguay. None of them operate their own infrastructure here. The $10/day fee pays for the billing agreement between your home carrier and Antel, not for better signal or faster speeds. A Uruguay eSIM on Antel costs $54.80 for 20GB — the same network, the same towers, at $2.74/GB instead of $10/day.

How AT&T triggers charges in Uruguay

AT&T's International Day Pass in Uruguay is not truly unlimited. Your domestic data cap applies to roaming — once exceeded, AT&T throttles your connection to 128 Kbps on Antel's network. At 128 Kbps, Google Maps tiles load in 20-30 seconds. Ride-hailing apps time out. Video calls are unusable. The $10/day charge does not pause when throttling starts — you pay the full daily rate for slow-speed access. Travelers with lower domestic data plans hit the throttle fastest. An eSIM provides a dedicated data allocation on Antel that does not interact with your domestic cap. 20GB at $54.80 gives you a separate data balance that does not depend on what you used before your trip.

Silent data drains that trigger roaming in Uruguay

Location Services on your phone ping Antel's towers every few minutes in Uruguay. Find My, Maps, Weather, and ride-hailing apps all request location data in the background. Each ping transfers 0.5-2 MB. Over a full day, location pings accumulate 10-30 MB of silent cellular data. At $2.05/MB, that is $20-60 per day in charges you never authorized. Disable location services for non-essential apps before landing: Settings > Privacy > Location Services > review each app. Keep Maps and emergency services active, disable everything else. An eSIM on Antel at $6.99 for 1GB routes these pings through flat-rate data instead of AT&T's per-MB billing.

Airport SIM markup explained for Uruguay

Physical SIM cards at many airport counters require passport registration. The counter agent photocopies your passport, enters your details into a local registry, and files the record before activating the SIM. This process adds 10-15 minutes per traveler beyond the counter wait time. An eSIM requires no passport registration — you provide a payment method and an email address. No government registry, no photocopy, no paper form. Plans on Antel start at $6.99 for 1GB. Install before departure, activate after landing, no registration paperwork required.

eSIM activation walkthrough for Uruguay

! Do this before step 2

Disable data roaming on your home SIM first. If your home SIM is still roaming-enabled when your eSIM activates, your carrier can charge both lines simultaneously. Settings → Cellular → Cellular Data Options → Data Roaming: OFF.

Disable data roaming on your home SIM

Go to Settings › Cellular › Cellular Data Options and turn Data Roaming OFF. This is the most critical step. Skipping it means Uruguay roaming charges can still hit your home carrier bill.

Buy a travel eSIM

Get a plan from Airalo at $2.74/GB. Do this at home on WiFi before you fly — QR code delivery takes under 60 seconds.

Install the eSIM profile

Open phone Settings › Cellular › Add eSIM. Scan the QR code or tap the install link in your confirmation email.

Set eSIM as default data on arrival

After landing in Uruguay, go to Settings › Cellular and set your travel eSIM as the primary data line. It connects to Claro within minutes.

Keep home SIM for calls via WiFi Calling

Your home number stays reachable for free over WiFi. You pay eSIM rates for data — 85–95% less than roaming.

iPhone settings for travel to Uruguay

On iPhone, disable roaming before landing in Uruguay: Settings > Cellular > Cellular Data Options > Data Roaming OFF. This single toggle blocks AT&T from billing through Antel's network. Then install your eSIM: Settings > Cellular > Add Cellular Plan > scan the QR code. After landing, go to Settings > Cellular and set your eSIM as the active data line. Keep "Allow Cellular Data Switching" off to prevent your home SIM from activating during eSIM coverage gaps. Your home SIM stays enabled for voice calls and WiFi Calling. The eSIM handles all data on Antel at $6.99 for 1GB.

Device-Specific Roaming Settings for Uruguay

iPhone Settings

iPhone 14 and newer models sold in the US are eSIM-only. Both SIM slots are digital. Open Settings > Cellular to see your installed lines. Tap your home carrier line (AT&T, Verizon, or T-Mobile). Turn off Data Roaming under Cellular Data Options. This one toggle prevents the $10/day charge on Antel in Uruguay. Next, install a Uruguay travel e SIM: Settings > Cellular > Add eSIM. Scan the QR code from your eSIM provider or use the provider's app. After installation, go to Settings > Cellular > Cellular Data and select the travel eSIM as your data line. Your home carrier stays active for calls and texts. The eSIM handles all data on Antel at $6.99 for 1GB. Over 7 days, this saves $63.01 versus AT&T Day Pass.

Samsung Settings

Samsung Galaxy S23 and earlier models running One UI 5: open Settings > Connections > Mobile Networks. Tap Data Roaming and toggle it OFF. For dual-SIM models, repeat this for each SIM slot under Settings > Connections > SIM Card Manager. Install a Uruguay eSIM: Settings > Connections > SIM Card Manager > Add Mobile Plan. Scan the QR code. Set the eSIM as your data SIM. The path differs slightly from One UI 6 (SIM Manager vs SIM Card Manager), but the result is identical: home carrier data roaming OFF, eSIM data on Antel at $6.99 for 1GB. AT&T charges $10/day on Antel for the same network your e-SIM accesses at a fixed price.

Pixel Settings

Google Pixel 9 and Pixel 8 on Android 15: open Settings > Network & Internet > SIMs. Tap your home carrier (AT&T, Verizon, or T-Mobile). Toggle Roaming OFF. This prevents the $10/day charge on Antel in Uruguay. Install a travel eSIM: Settings > Network & Internet > SIMs > Add SIM (or download from your provider's app). After scanning the QR code, return to Settings > Network & Internet > SIMs and tap the new e-SIM entry. Set it as your mobile data SIM. Your home carrier handles calls and texts. The eSIM handles all data on Antel at $6.99 for 1GB. Pixel phones support per-SIM roaming toggles, so roaming stays OFF on your home carrier and ON for the eSIM simultaneously.

Dual SIM Configuration

iPhone 14 and newer (US models) support two eSIM profiles simultaneously. Both your home carrier and your Uruguay travel eSIM are digital. Open Settings > Cellular to see both lines. Tap your home carrier line: turn Data Roaming OFF, confirm Voice & Data is set to your home carrier. Tap your travel e SIM line: turn Data Roaming ON, confirm it is set as the Cellular Data line. Go to Settings > Cellular > Cellular Data and select the travel eSIM. Verify: your home carrier shows "No Service" or "SOS Only" for data in Uruguay. Your eSIM shows Antel with signal bars. A 1GB plan at $6.99 on Antel handles all data. WiFi Calling on your home eSIM routes calls through your US carrier at domestic rates. Total roaming charge prevention: $0. Total eSIM cost: $6.99.

Data Usage Monitoring

Reset your iPhone data counter before activating your eSIM in Uruguay. Settings > Cellular > scroll to the bottom > Reset Cellular Statistics. This gives you a clean baseline for tracking eSIM usage on Antel. A 20GB plan over 7 days means a daily budget of 2.9 GB. Check Settings > Cellular > Cellular Data Usage daily to stay under budget. iOS does not reset automatically. Set a daily alarm to check consumption. If you hit 80% of your plan with days remaining, enable Low Data Mode and offload streaming to hotel WiFi. Top up through your eSIM provider's app if the balance drops to zero.

Roaming Avoidance Strategies for Uruguay

Offline Preparation

Download Uruguay in Google Maps before departure. Tap your profile icon, select Offline Maps, and download the regions you plan to visit. Offline maps include street-level navigation, Points of Interest, and basic search. This saves 3-5 MB per Maps session that would otherwise cost $6-10 at $2.05/MB without a roaming plan.
Save the local language for Uruguay in Google Translate (Settings > Offline Translation > download). Offline mode handles text, voice, and camera input without cellular data. Pre-translate hotel addresses, dietary restrictions, and emergency phrases before departure. Store translations as screenshots for instant offline access.
Download entertainment before departure. Netflix, Spotify, and podcasts all support offline downloads. A 7-day trip to Uruguay needs 5-10 hours of offline content for flights, transit, and downtime. Download on home WiFi. Streaming over an eSIM consumes 700 MB per hour of video, draining your plan quickly.
Install ride-hailing apps for Uruguay before arrival. Create your account and add a payment method on home WiFi. The app download and account setup consume 50-100 MB that you do not want running through a carrier roaming connection.
Download an offline currency converter app with UYU ($U) rates. XE and Currency apps both support offline mode after an initial rate download. The local currency in Uruguay is UYU. Pre-load the exchange rate on home WiFi so you can check prices without using cellular data at markets and shops.
Save booking confirmations, boarding passes, and hotel addresses as PDF files or screenshots on your device. Store them in the Files app or a dedicated folder. If your eSIM data runs out or you lose connectivity in Uruguay, offline documents keep your itinerary accessible. Email attachments consume 2-5 MB each to re-download.
Save 911 as Uruguay's emergency number in your contacts. Add your hotel address, embassy phone number, and travel insurance hotline. Store these as a contact card that works without internet access. Emergency calls work on any carrier network in Uruguay regardless of your eSIM or roaming status.

Messaging Alternatives

Coordinate with travel companions in Uruguay using WhatsApp group chats. Create the group before departure on home WiFi. Share itineraries, meeting points, and restaurant finds within the group. WhatsApp is the standard across Western and Southern Europe. Telegram has growing adoption in Eastern Europe. iMessage is common among iPhone users but does not cross the Android divide. Group messages consume 1-10 KB each. Photo sharing runs 1-3 MB per image. Share photos at lower resolution to conserve e SIM data. Location sharing on WhatsApp uses 0.5-1 MB per 15-minute session. AT&T charges $0.50 per SMS and $1-3/minute for calls on top of $10/day. WhatsApp on an eSIM at $6.99 for 1GB replaces all carrier messaging fees.

Bill Shock Prevention

AT&T

Open the myAT&T app or visit att.com/international before departure.
Check if International Day Pass ($10/day in Uruguay) is auto-enabled on your plan. If so, remove it under Account > International > Manage Day Pass.
Disable data roaming on your iPhone: Settings > Cellular > Cellular Data Options > Data Roaming OFF.
Disable data roaming on Android: Settings > Connections > Mobile Networks > Data Roaming OFF.
Install a Uruguay eSIM before boarding: 1GB on Antel from $6.99.
Set your eSIM as the primary data line: iPhone Settings > Cellular > Cellular Data > select eSIM line.
Turn off Background App Refresh for non-essential apps: Settings > General > Background App Refresh.
AT&T Day Pass resets at midnight US Eastern time, not UYT (UTC-3). A late-evening arrival in Uruguay can trigger two Day Pass charges in two hours.
After landing at the airport: verify data roaming is OFF on your AT&T line and ON for your eSIM line.
Check your AT&T account 48 hours after return. Dispute any charges within the first billing cycle. AT&T occasionally waives first-time roaming charges.
Total AT&T Day Pass cost for 7 days: $70. Total eSIM cost: $54.80 for 20GB. Savings: $15.20.

Verizon

Open the My Verizon app or visit verizon.com/travel before departure.
Check if TravelPass ($10/day, 2 GB high-speed cap in Uruguay) is active. Remove it under Plan > Travel > Remove TravelPass.
Verizon TravelPass auto-enrolls when your phone connects to Antel. The charge triggers before you clear customs at the airport.
Disable data roaming: iPhone Settings > Cellular > Cellular Data Options > Data Roaming OFF.
Android: Settings > Connections > Mobile Networks > Data Roaming OFF.
Install a Uruguay e-SIM before departure: 1GB on Antel from $6.99.
Verizon caps high-speed data at 2 GB per day on TravelPass. After the cap, speed drops to 600 Kbps for the rest of the day. The eSIM has no daily cap.
After landing at the airport: confirm your Verizon line shows "No Service" or "SOS Only." Your eSIM line should show Antel with signal bars.
Verify no TravelPass charges appear on your Verizon bill within 48 hours of return. Call 611 to dispute within the first billing cycle.
Total Verizon TravelPass cost for 7 days: $70. eSIM alternative: $54.80 for 20GB. Savings: $15.20.

T-Mobile

T-Mobile Magenta and Go5G include free international data in Uruguay, but speed is throttled to 256 Kbps.
At 256 Kbps: Google Maps takes 30+ seconds to load, ride-hailing apps time out, video calls fail, and photo uploads take 2-5 minutes each.
T-Mobile Go5G Plus adds 5 GB high-speed for $5/day. Go5G Next includes 15 GB/month at high speed. Check which plan you have in the T-Mobile app under Account > Plan Details.
Calls on T-Mobile cost $0.25/minute in Uruguay. Use WhatsApp or FaceTime calling over your eSIM data to avoid per-minute charges.
Install a Uruguay eSIM for full-speed data: 1GB on Antel at $6.99. Set the e SIM as your data line and keep T-Mobile for calls and texts.
T-Mobile's free 2G tier is useful for: text-only WhatsApp messages, basic email (no attachments), and low-bandwidth background sync. It is not useful for: Maps, photos, video, social media, or ride-hailing.
After your trip: check your T-Mobile bill for $0.25/minute call charges. Dispute within the first billing cycle if unexpected charges appear.

The Airport Roaming Trap in Uruguay

Your phone connects to Antel the moment the aircraft doors open at the airport. The immigration queue takes 20-60 minutes. During that wait, background apps sync email, check weather, and refresh notifications. AT&T's International Day Pass triggers on the first data byte. Verizon TravelPass auto-enrolls simultaneously. You have not opened a single app yet. The charge: $10 for AT&T, $10 for Verizon. Over 7 days: $70. Prevention: enable airplane mode before landing. Keep it on through customs. Install your eSIM on airport WiFi if not already installed. Activate the e SIM as your data line. Then disable airplane mode. Your phone connects to Antel through the eSIM at $6.99 for 1GB. No $10 trigger.

How to Avoid Roaming Charges in Uruguay

To avoid roaming charges in Uruguay, turn off data roaming in your phone settings and activate a travel eSIM on Antel.

AT&T, Verizon, and T-Mobile each charge differently for Uruguay roaming. AT&T: $10/day. Verizon: $10/day with 2GB cap. T-Mobile: free but throttled to 256 Kbps. An eSIM on Antel gives full 4G LTE speed for $54.80/20GB.

Go to Settings and disable Data Roaming on your carrier's SIM.
Buy a 20GB eSIM for Uruguay ($54.80 on Antel).
Add the eSIM: Settings > Cellular > Add eSIM > scan QR code.

Provider pick

Why Airalo for Uruguay

Airalo leads on price for Uruguay with 20GB at $54.80 on Antel's network. AT&T International Day Pass charges $10/day for the same Antel towers — $70 over 7 days. Airalo connects through identical infrastructure at $2.74/GB. The savings come from removing the carrier middleman. Your home carrier negotiates roaming agreements that add markup at every layer. Airalo contracts directly with Antel, passing the lower rate to you. Plans start at $6.99 for 1GB with no daily activation fee.

Networks

Tower coverage in Uruguay

Claro's towers serve millions of travelers in Uruguay each year. AT&T charges each of them $10 per day for the same signal an eSIM delivers at $54.80. The network infrastructure does not change between a roaming connection and an eSIM connection — Claro transmits the same data through the same towers either way. 5 eSIM providers listed here connect through Claro. Entry plans start at $6.99 for 1GB.

Privacy

Data privacy in Uruguay

Uruguay places no restrictions on VPN usage. Travelers can run any VPN provider on Antel's network without interference. This matters because public WiFi varies in reliability — and every unsecured WiFi connection exposes banking credentials, email passwords, and payment details. An eSIM on Antel at $6.99 for 1GB provides a private cellular connection that is inherently more secure than public WiFi. Layer your VPN on top of the eSIM connection for maximum privacy. This combination eliminates both AT&T's $10/day roaming charge and the security risks of relying on hotel WiFi.

Pricing

Price comparison: eSIM plans for Uruguay

What a travel eSIM costs in Uruguay versus carrier roaming.

WiFi in Uruguay is moderate, so cellular data carries most of the load. Size your eSIM plan accordingly — a 20GB plan at $54.80 covers 7 days of moderate use on Antel. AT&T charges $70 for the same period on the same network. Without reliable WiFi, you depend on cellular for navigation, translation, and communication. An eSIM ensures that dependency costs $54.80 instead of $70.

Multi-country

Visiting more than just Uruguay?

Uruguay eSIM plans start at $54.80 for 20GB on Antel. Neighboring countries: Argentina: $41.99 for 20GB; Bolivia: $118.62 for 20GB; Brazil: $35.63 for 20GB. AT&T charges $10/day in every one of these countries — the rate does not adjust by destination or local cost of living. A South America regional eSIM bundle often matches the cost of a single-country plan while covering all neighboring countries. Compare the regional bundle price against individual country plans before purchasing. If your trip crosses any border — even for a day trip from Uruguay to Argentina, Bolivia, and Brazil — the regional bundle eliminates the per-country AT&T penalty.

Local tips

What to know before you land in Uruguay

What your carrier does not tell you about Uruguay: Antel is state-owned with widest coverage. Pack a Type C/F/I/L power adapter for Uruguay.

Avoid these

Mistakes that cost travelers in Uruguay

Forgot to disable roaming

Data roaming left on triggers AT&T's $10/day charge the moment your phone connects to Antel in Uruguay. One push notification activates the full daily charge. Disable it in Settings before boarding, not after landing.

WiFi Assist left on

iOS WiFi Assist automatically switches to cellular when hotel WiFi weakens. In Uruguay, this routes data through your home SIM on Antel, triggering AT&T's $10/day charge mid-session. Disable WiFi Assist under Settings > Cellular before departure.

Day pass midnight reset misunderstood

AT&T's $10/day pass resets at midnight UYT (UTC-3) time — not local time in Uruguay. Landing at 10pm local time can trigger two separate $10 charges before you sleep. An eSIM on Antel at $6.99 has no midnight reset.

Not pre-installing the eSIM

An eSIM requires WiFi to scan and install the QR code. Trying to install at the airport means competing for congested airport WiFi under time pressure. Install the eSIM at home, 5-7 days before departure.

Leaving roaming on just in case

Keeping roaming on "just in case" costs $10/day on Antel whether you use any data or not. A single background push notification triggers the full charge. There is no safe way to leave roaming on while avoiding the fee in Uruguay.

The bottom line

Our take on roaming in Uruguay

Skip the SIM counter at the airport. Install a Uruguay eSIM before departure and land with 20GB on Antel already active for $54.80. AT&T charges $70 for the same network access over 7 days. The eSIM saves $15.20 and eliminates the queue, the passport scan, and the counter wait. Both the airport SIM and AT&T roaming use Antel's towers — only the price and the convenience differ. Buy the eSIM from your couch, not from a stressed counter agent in arrivals.

Common questions

Roaming charge questions and answers for Uruguay, answered

How do I disable roaming when using dual SIM for Uruguay?

With dual SIM, you need to disable roaming on your home SIM specifically. On iPhone: Settings > Cellular > select your home SIM line > Data Roaming (off). Then set the eSIM as your primary data line under Cellular Data. On Android: Settings > SIM Manager > select home SIM > Data Roaming (off). The eSIM stays set to allow data. This prevents AT&T from charging $10/day while your Uruguay eSIM handles data through Antel. Both SIM lines stay active: home SIM for calls and texts, eSIM for data at $6.99 instead of carrier roaming rates.

How much can background apps cost while roaming in Uruguay?

A typical smartphone performs 15 background syncs per hour, each transferring 3-5 MB. That is 45-75 MB/hour in invisible data usage. At AT&T's $2.05/MB roaming rate on Antel, 8 hours of sleeping with roaming enabled costs $738-1,230. Even with AT&T Day Pass ($10/day), data caps at 2 GB can trigger overage throttling. Common background consumers: iCloud sync (50 MB/day), Google Drive (30 MB/day), email accounts (20 MB/day), push notifications (10 MB/day), and app updates (100+ MB when queued). Disable all background activity before arriving in Uruguay or install an eSIM at $6.99 and let apps sync at flat-rate pricing.

What happens if I forget to turn off roaming in Uruguay?

Your phone connects to Antel and AT&T charges $2.05/MB without a plan. A single 50 MB background sync costs over $100. With AT&T International Day Pass, you pay $10 the moment any data is used, even a push notification. Act immediately: turn on Airplane Mode, go to Settings > Cellular > Cellular Data Options > Data Roaming and switch it off, then disable Airplane Mode. Your home SIM resumes voice and SMS without data. Install an eSIM ($6.99 for 1GB on Antel) to restore data access. Call your carrier within 48 hours because AT&T and Verizon both waive first-time roaming overcharges if reported in the same billing cycle.

Does an eSIM get the same coverage as roaming in Uruguay?

Yes. An eSIM connects to Antel, the same network infrastructure AT&T and Verizon use for roaming in Uruguay. You get identical towers, identical coverage area, and the same 4G LTE speeds. The only difference is billing: your carrier charges $10/day or $2.05/MB for roaming access to these towers, while the eSIM charges $2.74/GB for the same connection. There is no coverage penalty for using an eSIM. In many cases, eSIM data speeds are faster because carrier roaming agreements sometimes throttle international users to lower priority.

How much does roaming cost for a family traveling to Uruguay?

AT&T and Verizon charge Day Pass fees per line, not per account. A family of four on AT&T Day Pass pays $40/day in Uruguay, totaling $280 for a 7-day trip. Children's phones are particularly risky because apps and games download updates in the background. One child's iPad streaming a YouTube video at $2.05/MB racks up $400+ in under an hour. Four eSIMs on Antel cost roughly $71.96 total for 3 GB each. Share one eSIM's hotspot to cover all devices and cut costs further.

Will my WhatsApp number change if I use an eSIM in Uruguay?

No. Your WhatsApp number is linked to your home phone number, not your data SIM. Installing an eSIM for Uruguay data does not affect your WhatsApp registration. Keep your home SIM active in the second SIM slot for SMS verification if WhatsApp ever re-verifies your number. All your chats, groups, and contacts stay exactly the same. The eSIM on Antel at $6.99 provides the data connection for sending and receiving messages. Your home SIM provides the phone number identity. Both work simultaneously through dual-SIM on any modern smartphone.

What happens to my home number while using an eSIM in Uruguay?

Your home number stays fully active. With dual-SIM setup, your home SIM keeps your phone number for calls and texts while the Uruguay eSIM handles data on Antel. You receive calls on your home number. SMS messages arrive normally. Data routes through the eSIM at $6.99 instead of your carrier's $10/day roaming. On iPhone, set Cellular Data to the eSIM line and Default Voice to your home SIM. Both lines work simultaneously. Your home number is not affected by the eSIM installation and remains active throughout your entire trip.

Does a Uruguay eSIM work outside major cities?

Coverage depends on Antel's infrastructure outside urban areas. 4G LTE is available in major cities and populated areas. Rural regions may fall back to 4G or 3G. This is the same coverage map AT&T and Verizon roaming use because they connect to Antel's towers. Check Antel's coverage map before departure for your specific destinations. An eSIM at $6.99/GB gives you the same rural coverage as carrier roaming at a fraction of the cost. If your itinerary includes remote areas, download offline maps before leaving WiFi coverage.

How do I configure data roaming settings for Uruguay?

Complete setup before departure: (1) Disable Data Roaming on iPhone: Settings > Cellular > Data Roaming (off); Android: Settings > Connections > Mobile Networks > Data Roaming (off). (2) Turn on Airplane Mode before landing to block automatic carrier attachment to Antel. (3) Activate your pre-installed eSIM on local WiFi or after landing. (4) Set your home SIM to calls-only or data-off. Your home number stays active for calls and SMS; the eSIM handles all data without triggering your carrier's $10/day roaming rate.

Is my carrier's international add-on worth it for Uruguay?

No. AT&T International Day Pass and Verizon TravelPass both cost $10/day, activated the moment any background app touches your data connection. A 7-day Uruguay trip costs $70 in carrier add-on fees. A Uruguay eSIM for the same 7 days costs $54.80 on 20GB, which is 22% cheaper with no activation risk from background data. Carrier add-ons are only worth considering for single-day trips where eSIM installation is not feasible.

Is ship WiFi enough to avoid roaming charges near Uruguay?

Ship WiFi packages are the correct tool for internet access at sea. Plans range from $15-35/day for basic browsing to $35-60/day for streaming packages. Disable cellular data and use WiFi only while at sea. Ship WiFi works for messaging apps, email, and light browsing. Video calls and streaming require higher-tier packages. The limitation: ship WiFi does not work during port stops when you are ashore in Uruguay. For port days, use your eSIM at $6.99 on Antel's shore network. Airplane Mode plus ship WiFi at sea, eSIM on shore, eliminates all surprise maritime or carrier roaming charges.

Should I reset my data counter when I arrive in Uruguay?

Yes. Reset your phone's data statistics on arrival so all consumption tracked reflects only your Uruguay trip. On iPhone: Settings > Cellular > scroll to the bottom > Reset Statistics. This zeroes out the "Current Period" counter. On Android: Settings > Connections > Data Usage > tap the three-dot menu > Reset Statistics. After resetting, every MB counted belongs to your time on Antel in Uruguay. This makes it easy to track how much of your eSIM plan at $6.99 you have consumed without arithmetic from a previous trip or home usage. Check the counter each morning to gauge your daily consumption rate.

Will I get charged if my phone is in my pocket in Uruguay?

Yes. Your phone does not need to be in your hand to trigger roaming charges in Uruguay. Background processes sync email, update weather, refresh social feeds, and ping location services automatically through Antel. AT&T International Day Pass activates the moment any data crosses the connection, even a single push notification received while your phone sits in your pocket. That costs $10 for the calendar day. Disable data roaming before landing: Settings > Cellular > Data Roaming (off). Without this step, your phone generates charges from Antel without you touching it. An eSIM at $6.99 handles all background syncs at flat-rate pricing.

Can I make FaceTime calls with my number using an eSIM in Uruguay?

Yes. FaceTime uses your Apple ID for identification, not your data SIM. Your FaceTime caller ID shows your home phone number or email regardless of which SIM provides data. A FaceTime video call through the Uruguay eSIM on Antel uses approximately 3-8 MB per minute. The call recipient sees your normal number. FaceTime audio calls use 1-2 MB per minute. Keep your home SIM active for Apple ID verification. Set your eSIM as the cellular data line in Settings > Cellular. FaceTime routes through the eSIM data at $6.99 with no change to your caller identity.

If something goes wrong

When your eSIM does not connect in Uruguay

QR code not scanning (carrier lock)

If the QR code scan fails during installation, your phone may be carrier-locked to your home network. Contact your home carrier to confirm your device is unlocked before traveling to Uruguay. Carrier-locked phones cannot install eSIM profiles from any other provider.

Plan activated before landing

If you activated your Uruguay eSIM before landing, it may start consuming data before you arrive. Keep the eSIM profile toggled off in Settings until you land at the airport. Activate it only after clearing customs to avoid using data before your trip starts.

eSIM not showing in Settings

If your eSIM profile does not appear in Settings after scanning the QR code, restart your device. On iPhone, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This resets cellular configuration and forces the eSIM profile to appear.

LTE not connecting (fallback to LTE)

If LTE connectivity is weak on Antel in Uruguay, try setting your phone to 3G/WCDMA in Settings > Cellular > Cellular Data Options. LTE provides reliable speeds for navigation and messaging in most areas of Uruguay.

Provider app shows data used but phone shows none

Discrepancies between your provider's dashboard and your phone's data usage counter in Uruguay are normal — carrier billing and device-side tracking update at different intervals. Trust your provider's dashboard for accurate remaining balance on Antel. Phone counters reset with network settings changes.
