Know Your Carrier's Rates
AT&T: $10/day (auto-triggered). Verizon: $10/day (2GB cap). T-Mobile: free at 256 Kbps (too slow for maps). Without any plan: $2.05/MB. Know these numbers so you can calculate what you are saving.
At the Airport
When to Activate Your eSIM
After clearing customs at Changi (SIN), before leaving the terminal. Do not enable your eSIM during layovers. Each country your phone connects to triggers a separate carrier charge. Your eSIM plan timer starts at first network connection.
Airport SIM Counter vs eSIM
Changi (SIN) has SIM card kiosks. Typical cost: $12-30 for 100GB / 7-28 days. Wait time: 5-10 min; Changi has multiple options across terminals. Your eSIM is already installed. No queue, no language barrier, no passport handover.
Transit passengers at Changi (SIN) cannot access the arrivals terminal where SIM counters operate. Airside transit — staying past immigration — means no access to any retail counter. Your phone connects to Singtel regardless, and AT&T charges $10/day for that airside connection. Even a 4-hour layover in Singapore costs $10 in AT&T roaming without a plan. An eSIM activates without passing immigration — the QR code installs before you board and connects to Singtel through the eSIM profile, not your home carrier's roaming agreement. A transit traveler pays $5.49 for 1GB instead of $10 for four hours airside.
Airport WiFi
WiFi at Changi (SIN) is available for eSIM QR code installation if you did not install at home. Speed and reliability vary. Free tiers are typically time-limited.
First Connection Test
- Open your browser and load any page to confirm data works
- Check the status bar for Singtel carrier name
- Verify your home SIM still receives calls
- Run a speed test at fast.com
iPhone Roaming Settings for Singapore
iOS 18 adds a Cellular Data toggle in Control Center. Swipe down from the top-right corner of your iPhone. Long-press the connectivity panel. Tap the SIM selector to switch data between your home carrier and your Singapore eSIM. This is the fastest way to verify which line carries data after landing at Changi (SIN). For the one-time setup: Settings > Cellular > tap your AT&T or Verizon line > Cellular Data Options > Data Roaming OFF. Install the eSIM: Settings > Cellular > Add eSIM > scan QR code. Set the eSIM as data line. AT&T's $10/day charge triggers on the first data byte through Singtel on your home SIM. The Control Center toggle lets you verify your eSIM is active in 2 seconds.
Samsung Roaming Settings for Singapore
Samsung Galaxy S24 and S25 run One UI 6 with a dedicated SIM Manager. Open Settings > Connections > SIM Manager. Tap your home carrier (AT&T, Verizon, or T-Mobile). Toggle Data Roaming OFF. This prevents the $10/day charge when your Galaxy connects to Singtel at Changi (SIN). Install a Singapore eSIM: Settings > Connections > SIM Manager > Add eSIM. Scan the QR code or enter the activation code from your eSIM provider. After installation, tap the eSIM entry in SIM Manager and set it as your Mobile Data line. Your home carrier handles calls and texts. The e SIM routes data through Singtel at $5.49 for 1GB. Over 4 days: $34.51 in savings versus AT&T.
Pixel Roaming Settings for Singapore
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 Singtel in Singapore. 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 Singtel at $5.49 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 for Singapore
iPhone 14 and newer (US models) support two eSIM profiles simultaneously. Both your home carrier and your Singapore 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 Singapore. Your eSIM shows Singtel with signal bars. A 1GB plan at $5.49 on Singtel 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: $5.49.
WiFi Calling Setup for Singapore
WiFi Calling works over hotel WiFi in Singapore. When WiFi is unavailable, your eSIM data can carry the call instead. iPhone: Settings > Phone > WiFi Calling > WiFi Calling on This iPhone ON. Also enable "Prefer WiFi" under Calls On Other Devices. Samsung: Settings > Connections > WiFi Calling ON, then check "Prefer WiFi for calls." Your home SIM uses WiFi first for voice. When WiFi drops, the call transfers to your e SIM data on Singtel at plan rates (no per-minute charge through VoIP). This dual-path setup means your calls never touch carrier roaming. WiFi handles calls at zero cost. eSIM data handles calls through WhatsApp or FaceTime when WiFi is unavailable. AT&T's $1-3/minute voice roaming charge never triggers because your home SIM's data roaming is OFF.
Background App Settings for Singapore
Background App Refresh (iPhone)
Settings > General > Background App Refresh
Disable globally or per-app. Background refresh on Singtel in Singapore consumes 50-200 MB/day without you opening any app. At $2.05/MB without a roaming plan, that is $102-410/day in silent charges. With an eSIM, this data counts against your plan. Disable for social media, news, and shopping apps. Keep enabled for Maps and messaging.
Mail Fetch vs Push (iPhone)
Settings > Mail > Accounts > Fetch New Data
Switch from Push to Fetch (every 30 minutes or Manual). Push email checks Singtel's network every 15-60 seconds in Singapore. At SGT (UTC+8) timezone, overnight pushes sync while US colleagues send daytime emails. Fetch reduces email data by 60-80% compared to Push. Each push check: 0.5-2 MB.
iCloud Photos cellular upload (iPhone)
Settings > Photos > Cellular Data OFF
iCloud uploads every photo to the cloud over cellular by default. After a day of sightseeing in Singapore, 50-200 photos queue for upload overnight. Each high-res photo: 3-8 MB. Total overnight upload on Singtel: 150-1,600 MB. At $2.05/MB: $307-3,280 without a plan. With an eSIM, this drains your data balance. Upload photos manually on hotel WiFi instead.
Data Saver (One UI) (Samsung)
Settings > Connections > Data Usage > Data Saver ON
Samsung Data Saver restricts background data for all apps except whitelisted ones. Whitelist Maps, your messaging app, and your eSIM provider app. Block background data for social media, streaming, and news. This reduces background consumption on Singtel in Singapore by 30-50%. Your eSIM data lasts longer without manual intervention.
Auto-sync toggle (Samsung)
Settings > Accounts and Backup > Manage Accounts > Auto Sync Data OFF
Auto-sync pushes email, contacts, calendar, and app data over Singtel in Singapore. Disabling auto-sync stops all account synchronization on cellular. Sync manually on hotel WiFi. Re-enable auto-sync when you return home. This single toggle prevents the largest category of background data usage on Samsung devices.
Adaptive Battery and data (Pixel)
Settings > Battery > Adaptive Battery ON
Pixel's Adaptive Battery restricts background activity for infrequently used apps. In Singapore, this reduces unnecessary data consumption on Singtel without manual app-by-app management. Keep Adaptive Battery ON. It learns your usage pattern and limits background data for apps you rarely open while traveling.
Set data warning and limit (Pixel)
Settings > Network & Internet > SIMs > eSIM > Data Warning & Limit
Set a data warning at 80% of your eSIM plan and a hard limit at 95%. Pixel shows a notification when you approach the warning threshold. The hard limit stops cellular data before you exceed your plan in Singapore. This prevents overage charges on prepaid eSIM plans and unexpected top-up costs on Singtel.
Automatic App Downloads (iPhone)
Settings > App Store > App Downloads: toggle OFF for cellular
A single app update runs 50-500 MB. At $2.05/MB on Singtel in Singapore: $102-1,025 per update without a plan. With an eSIM, one update can consume 10-50% of a small data plan. Disable automatic downloads. Update apps manually on hotel WiFi only. Check for updates before departure so critical apps are current.
Airplane Mode Sequence for Singapore
After landing at Changi (SIN), verify your dual-SIM configuration before disabling Airplane Mode. Check list: (1) Home SIM Data Roaming OFF. (2) eSIM set as Cellular Data line. (3) eSIM Data Roaming ON (allows Singtel connection). iPhone: Settings > Cellular > verify both lines. Samsung: Settings > SIM Manager > verify both lines. Pixel: Settings > Network & Internet > SIMs > verify both. Only after confirming all three settings: disable Airplane Mode. Your phone connects to Singtel through the e SIM at $5.49 for 1GB. If any setting is wrong, Airplane Mode keeps you safe. Fix the setting, then disable Airplane Mode. Zero risk of a $10 AT&T trigger.
Data Usage Monitoring in Singapore
Reset your iPhone data counter before activating your eSIM in Singapore. Settings > Cellular > scroll to the bottom > Reset Cellular Statistics. This gives you a clean baseline for tracking eSIM usage on Singtel. A 10GB plan over 4 days means a daily budget of 2.5 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.
Singapore-Specific Device Settings
Enable manual network selection near border zones in Singapore. iPhone: Settings > Cellular > Network Selection > turn off Automatic > select Singtel. Samsung: Settings > Connections > Mobile Networks > Network Operators > Search Now > select Singtel. Pixel: Settings > Network & Internet > SIMs > eSIM > Advanced > Automatically Select Network OFF > select Singtel. Manual selection prevents your phone from connecting to a neighboring country's carrier when foreign signals bleed across the border.
Switch email from Push to Fetch in Singapore. The SGT (UTC+8) timezone means US business hours overlap with your nighttime. Push email checks Singtel's network every 15-60 seconds while you sleep. Each check costs 0.5-2 MB at $2.05/MB without a plan. iPhone: Settings > Mail > Accounts > Fetch New Data > switch to Every 30 Minutes or Manually. Android: open your email app Settings > Sync frequency > Every 30 Minutes or Manual.
Physical SIM cards in Singapore require passport registration. Passport required for prepaid SIM purchase; instant activation An eSIM bypasses this requirement entirely. No store visit, no passport scan, no activation wait. Install before departure on home WiFi. The e-SIM connects to Singtel after landing without any registration step. This is the single largest convenience advantage of an eSIM in countries with SIM registration requirements.
Turn Off Roaming: Singapore Device Guide
iPhone
Open Settings, tap Cellular, tap Cellular Data Options, and switch Data Roaming off. This prevents AT&T from charging $10/day in Singapore.
iPhone dual-SIM setup in Singapore: keep your primary SIM for calls (Data Roaming off), add an eSIM for data on Singtel. Set the eSIM as your default data line in Settings > Cellular. Total cost: $13.99 vs $40 roaming.
Samsung
On Samsung One UI, the Data Roaming toggle is at Settings > Connections > Mobile Networks. Turn it off before your trip to Singapore.
After toggling Data Roaming off on Samsung, go to Settings > Connections > Data Usage > Mobile Data Usage to monitor eSIM consumption in Singapore. The 10GB plan at $13.99 covers a 4-day trip.
Pixel
To turn off roaming on Google Pixel before visiting Singapore, go to Settings > Network & Internet > SIMs > select your carrier > toggle Roaming off.
With Roaming disabled, your Pixel phone will not bill through your carrier in Singapore. Add a travel eSIM: Settings > Network & Internet > SIMs > Add SIM. Scan the QR code for 10GB on Singtel at $13.99.
Getting Data in Singapore
Best Way to Get Data
The best way to get data in Singapore is a travel eSIM on Singtel — 10GB for $13.99, activated before you land.
Local SIMs require passport registration at the counter. An eSIM skips the counter entirely. You buy it online, scan a QR code, and connect to Singtel's 5G network. The 10GB plan costs $13.99 and lasts your entire 4-day trip.
- Check that your phone supports eSIM (iPhone XS+, Samsung Galaxy S21+, Pixel 3+).
- Buy a Singapore eSIM: 10GB on Singtel for $13.99.
- Scan the QR code: Settings > Cellular > Add eSIM (iPhone) or SIM Manager (Samsung).
- Disable carrier data roaming to prevent simultaneous charges.
- Land in Singapore with data already active on Singtel.
An eSIM costs $13.99 vs carrier roaming at $40 or airport SIM at $12-30 for 100GB / 7-28 days+.
Do You Need an eSIM?
An eSIM is the best option for data in Singapore if you want full 5G speed without daily roaming charges. Alternatives: airport SIM (queues), pocket WiFi (bulk), or carrier roaming ($10/day).
An eSIM is particularly valuable in Singapore if you need real-time navigation, language translation, or video calls. WiFi alone cannot support these use cases reliably. The 10GB plan costs $13.99 and lasts 4+ days.
With an eSIM, a 4-day trip to Singapore costs $13.99 for data. Carrier roaming costs $40.
Top Roaming Tip for Singapore
Singapore roaming costs $10/day with US carriers. Switch to an eSIM: 10GB on Singtel for $13.99. Turn off roaming, keep your number, save $26.
During Your Stay
Stretch Your Data
- Use WiFi for downloads and streaming
- Keep video quality at 480p on cellular
- Disable auto-play on social media feeds
- Use offline maps for navigation
- Compress photos before uploading
WiFi Hunting in Singapore
WiFi availability: excellent. Wireless@SG provides free public WiFi island-wide; excellent coverage in MRT, malls, and public spaces
Tethering and Hotspot
Share your eSIM data with travel companions via Personal Hotspot. Most eSIM providers allow tethering. Holafly supports it on all plans. Airalo supports it on most plans. Battery drains faster with hotspot enabled.
Top Up If You Run Out
Buy more data through the provider app. Or purchase a second eSIM. Switch to unlimited daily at $3.35/day for worry-free data. eSIM installation refresher →
Peak Season Warning
Network congestion increases during Singapore's peak season (Dec-Jan, Jun-Aug). Year-round destination; peak during Christmas/New Year and European summer holidays
Prices stable year-round; frequent promotions at carrier stores. AT&T's $10/day roaming charge does not shift at all — it stays fixed during Dec-Jan and Jun-Aug and every other month. Verizon TravelPass holds at the same $10/day year-round. This means roaming costs represent a larger percentage of your travel budget during off-peak months when flights are cheaper. A 4-day trip always costs $40 in AT&T day passes regardless of season. A 10GB eSIM on Singtel at $13.99 stays flat too, but at a fraction of the carrier rate. The savings percentage increases when your other travel costs drop.
Roaming mistakes that add up in Singapore
The Push Notification Trap
One push notification triggers AT&T's $10 daily charge. Weather widgets, email sync, WhatsApp pings. The charge resets at midnight Eastern, not Singapore local time.
The WiFi Drop Trap
Walking out of hotel WiFi range triggers a carrier connection on Singtel. One webpage load on your home SIM costs $10. Keep home SIM data roaming OFF.
The Background Sync Trap
iCloud backup overnight at per-MB rates: $1,025-2,099. A single app update (200 MB): $410. Photo sync and email attachment downloads add up fast. Disable all background sync on your home SIM before departure.
The Departure Day Trap
Carrier charges apply on departure day. Your phone connects to Singtel at Changi (SIN) during check-in, triggering an extra $10 charge. Disable roaming on your home SIM before leaving your hotel.
The Transit Layover Trap
Each country layover triggers a separate $10/day charge. A flight with one layover means two countries, two charges. Keep airplane mode on during all layovers.
More Mistakes to Avoid
Forgot to disable roaming
Data roaming left on triggers AT&T's $10/day charge the moment your phone connects to Singtel in Singapore. One push notification activates the full daily charge. Disable it in Settings before boarding, not after landing.
Auto app updates left on
Automatic app updates consume hundreds of megabytes overnight. At $2.05/MB on Singtel, two app updates can cost $400 or more. Disable automatic updates under App Store settings before traveling to Singapore.
Relying solely on hotel WiFi
Hotel WiFi in Singapore drops unexpectedly. Your phone falls back to Singtel through your home SIM the moment WiFi cuts out, activating AT&T's $10/day charge automatically. An eSIM makes every cellular fallback cost-free.
Money-Saving Tricks
eSIM Stacking
Visiting multiple countries? Buy a regional eSIM instead of per-country plans. Airalo offers Asialink, Eurolink, and other regional options. Delete expired profiles to free eSIM slots on your phone.
WiFi Calling for Free Voice
Use WiFi Calling on your home number for free inbound and outbound calls. iPhone: Settings > Phone > WiFi Calling. Android: Settings > Network > WiFi Calling. Works alongside your eSIM data. No per-minute carrier roaming charges.
Offline Everything
Download before departure: maps, translation packs, entertainment (Netflix and Spotify offline mode), boarding passes, and hotel confirmations. This reduces daily data usage from 1.5 GB to under 500 MB.
Local Prepaid Alternative
A local prepaid SIM in Singapore costs approximately $10-20 for 30-100GB / 14-28 days. Requires passport and in-person registration. An eSIM advantage: no store visit, no wait, pre-installed before departure.
Family and Group Savings
4 phones × $10/day × 4 days = $160 carrier cost. 4 eSIMs at $5.49 each = $21.96. Savings: $138.04. Or share one eSIM via hotspot for even more savings.
Roaming answers for Singapore roaming tips
How do I turn off data roaming on my iPhone for Singapore?
Go to Settings > Cellular > Cellular Data Options > Data Roaming and toggle it off. Do this before boarding. Once your phone detects Singtel's tower in Singapore, AT&T charges $10/day the instant any data crosses the connection. On Android: Settings > Connections > Mobile Networks > Data Roaming (off). After disabling roaming, install your Singapore eSIM while still on home WiFi. Set the eSIM as your data line before landing. Your home SIM stays active for calls and texts while the eSIM handles all data without touching your carrier plan.
Does Low Data Mode prevent roaming charges in Singapore?
Low Data Mode reduces background data but does not prevent roaming charges. On iPhone (Settings > Cellular > Cellular Data Options > Low Data Mode), it pauses automatic updates, reduces image quality, and limits background downloads. This cuts usage by roughly 40-60%. On Android, Data Saver (Settings > Network > Data Saver) does the same. The problem: even with Low Data Mode active, remaining background activity at AT&T's $2.05/MB rate on Singtel still generates $30-80/day in charges. Low Data Mode is useful alongside an eSIM (starting at $5.49) to stretch your data plan, but it is not a substitute for disabling roaming entirely.
What happens if I forget to turn off roaming in Singapore?
Your phone connects to Singtel 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 ($5.49 for 1GB on Singtel) 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.
Is an eSIM worth it for a long trip to Singapore?
For trips longer than 3 days, an eSIM saves significantly. A 14-day trip on AT&T Day Pass costs $140. A 30-day trip costs $300. The eSIM for Singapore costs $20.49 for 20GB regardless of duration (plans typically cover 7-30 days). For extended stays, you can purchase a second eSIM when the first expires. Two eSIMs at $40.98 total still costs less than 5 days of carrier roaming. T-Mobile offers free throttled data at 256 Kbps internationally, but that speed is unusable for maps, video calls, or photo sharing. The eSIM connects to Singtel at full 5G speeds.
How much does roaming cost for a family traveling to Singapore?
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 Singapore, totaling $160 for a 4-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 Singtel cost roughly $23.96 total for 3 GB each. Share one eSIM's hotspot to cover all devices and cut costs further.
Should I use WiFi Calling or an eSIM for calls in Singapore?
Use both. WiFi Calling routes calls through your home carrier over WiFi, using your home minutes. It is free on most US carrier plans. The limitation: WiFi Calling only works when connected to WiFi, not mobile data. An eSIM on Singtel at $5.49 gives you mobile data everywhere. Use WhatsApp or FaceTime over eSIM data for calls when WiFi is unavailable. Enable WiFi Calling before departure: iPhone Settings > Phone > WiFi Calling. When on hotel WiFi, calls route free through your home carrier. When on mobile data, use WhatsApp calls through the eSIM.
Should I set up call forwarding before traveling to Singapore?
Call forwarding sends all calls to another number (such as a Google Voice number), avoiding per-minute roaming charges on incoming calls. Set up before departure: iPhone dial *72 followed by the forwarding number. Android: Settings > Phone > Call Forwarding. Forward to a VoIP number that rings over data. This way, incoming calls arrive through your eSIM's data on Singtel at $5.49 instead of your carrier's $1.00-1.29/minute roaming rate. Disable forwarding after returning home: dial *73 (iPhone/AT&T) or turn off in settings. Test forwarding at home before your trip to Singapore.
Which is the best carrier network for Singapore?
Singtel is the primary network for travel eSIMs in Singapore, with StarHub and M1 as alternatives. Singtel offers the widest coverage footprint and strongest 5G infrastructure. Travel eSIM providers select Singtel because of network reliability and roaming agreements. This is the same carrier AT&T and Verizon partner with for roaming. The difference is cost: AT&T charges $10/day for access, while an eSIM on Singtel costs $5.49/GB. Network quality is identical because you connect to the same towers, same spectrum, same base stations.
How do I configure data roaming settings for Singapore?
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 Singtel. (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 Singapore?
No. AT&T International Day Pass and Verizon TravelPass both cost $10/day, activated the moment any background app touches your data connection. A 4-day Singapore trip costs $40 in carrier add-on fees. A Singapore eSIM for the same 4 days costs $13.99 on 10GB, which is 65% 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.
Do I need to register a SIM card in Singapore?
Passport required for prepaid SIM purchase; instant activation This applies to local physical SIM cards only. A travel eSIM installed before departure does not require local registration. It activates through your provider's app and connects to Singtel without any in-person paperwork. Plans start at $5.49.
What if I cannot communicate at a SIM store in Singapore?
Language barriers at SIM card stores cause incorrect plan purchases, unwanted add-ons, and activation failures. Staff at airport counters in Singapore usually speak basic English, but stores outside tourist areas may not. Explaining your data needs, understanding the plan terms, and resolving activation issues in another language wastes time. An eSIM eliminates this entirely. Purchase online in English (or your language), install via QR code, and activate from your phone settings. Plans on Singtel start at $20.49 for 20GB. The purchase, installation, and activation all happen in your language on your device.
How do I get data if I arrive in Singapore late at night?
An eSIM is the only reliable option for late-night arrivals. Airport SIM counters close between 10pm and 6am in most airports. Changi (SIN) counters may have limited hours. Carrier stores outside the airport are closed. Your carrier's roaming activates automatically but costs $10/day. With an eSIM pre-installed, you land and have data on Singtel immediately, regardless of time. Navigate to your hotel, call a taxi, and check messages without finding an open store. Install the eSIM at $5.49 on your home WiFi before departure. It sits dormant until you activate it in Singapore.
How do I check if my Samsung phone is unlocked for a Singapore eSIM?
On Samsung One UI: Settings > Connections > SIM Manager. If you see "Add eSIM," your phone is both unlocked and eSIM-compatible. If that option is missing, your phone may be carrier-locked. Call your carrier (AT&T: 611, Verizon: 800-922-0204, T-Mobile: 611) and request an unlock. Samsung Galaxy S20 and newer support eSIM. On stock Android (Pixel): Settings > Network & Internet > SIMs > "Add SIM" confirms eSIM support. Unlocked phones connect to Singtel in Singapore at $5.49. Check at least 7 days before your trip because unlock processing takes 24-72 hours.
Save money on data in Singapore.
A 1GB eSIM costs $5.49 on Singtel. AT&T charges $40 for the same 4 days.
