How to keep your phone on without roaming in Paraguay
AT&T charges $10 for every day your phone connects to Tigo PY in Paraguay. That is $70 over 7 days — paid in US dollars while the local currency is PYG (₲). Background app syncs in the PYT (UTC-4/-3) time zone count toward that daily charge, even at 3am local time while you sleep.
The fix takes two steps before your flight. First, disable cellular data roaming in your phone settings — this blocks your home carrier from connecting. Second, install a Paraguay eSIM that covers 20GB on Tigo PY for $52.92. After landing, set the eSIM as your data line. Your home number stays active for WiFi Calling.
A full breakdown of roaming charges in Paraguay
One hour of normal phone use in Paraguay — Maps, emails, background refresh — consumes 100 MB. At $2.05/MB on Tigo PY, that is $205 in a single hour. Most travelers use their phone 4-6 hours per day on a trip. Over 7 days at moderate use, the total reaches $22 without a plan. AT&T's Day Pass caps the damage at $70, but a 20GB eSIM on Tigo PY costs $52.92 for the entire trip — the same network at a fraction of the hourly roaming rate.

Daily roaming math for Paraguay
Four phones on AT&T in Paraguay: $40/day. Over 7 days: $280. Each device bills $10/day independently on Tigo PY — a child's game, a partner's map search, a grandparent's text all trigger separate daily charges. Four eSIMs on Tigo PY cost $211.68 total for 20GB each. Family savings: $68.32. Per device, per day: AT&T = $10. eSIM = $7.56. The math scales as badly for families as it does for individuals.
Daily roaming charges for Paraguay
AT&T International Day Pass charges $10/day in Paraguay. Verizon TravelPass charges $10/day. Both connect through Tigo PY 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 Tigo PY's towers in Paraguay. None of them operate their own infrastructure here. The $10/day fee pays for the billing agreement between your home carrier and Tigo PY, not for better signal or faster speeds. A Paraguay eSIM on Tigo PY costs $52.92 for 20GB — the same network, the same towers, at $2.65/GB instead of $10/day.
How AT&T charges roaming in Paraguay
Dual-SIM phones in Paraguay carry a specific risk: both SIM lines can receive data connections simultaneously. If your home SIM has data roaming enabled and your eSIM is also active, your phone may route some traffic through the home SIM's roaming connection and some through the eSIM. AT&T charges $10/day for any data through the home SIM, even a single background sync. Set your eSIM as the primary data line in Settings and disable data roaming on your home SIM before leaving your hotel. Verify in Settings that "Cellular Data" shows your eSIM line, not your home carrier. An eSIM on Tigo PY at $52.92 for 20GB handles all data cleanly when configured as the sole data source.
Silent data drains that trigger roaming in Paraguay
iCloud and Google Photos upload every image on your camera roll overnight in Paraguay. A typical nightly backup pushes 500 MB to 1 GB through Tigo PY's network while you sleep. At $2.05/MB, a 500 MB backup costs $1,025. A 1 GB backup costs $2,050. Your phone does not ask permission. The upload starts the moment your device connects to cellular data and detects unsynced photos. Disable iCloud Photos backup on cellular before landing: Settings > Photos > Cellular Data (off). On Android, open Google Photos > Settings > Backup > Use cellular data (off). An eSIM on Tigo PY at $5.49 for 1GB turns this nightly upload into a flat-rate expense instead of a four-figure surprise.
Airport SIM markup explained for Paraguay
You land in Paraguay at 11:45pm and the airport SIM counter is closed. The next shift starts at 7am. Your options: pay AT&T $10/day on Tigo PY until morning, or use a pre-installed eSIM that activates the moment airplane mode turns off. Airport SIM counters at the airport operate on local business hours, not your flight schedule. Red-eye arrivals, early-morning landings, and delayed flights all arrive outside counter hours. An eSIM on Tigo PY installs before you leave home — 1GB for $5.49, active on landing regardless of the hour. No counter, no waiting for business hours, no $10 overnight charge.

iPhone settings for travel to Paraguay
Dual-SIM phones traveling to Paraguay require explicit data line assignment to avoid accidental roaming charges. After installing your Paraguay eSIM, go to your phone's SIM settings and confirm that: (1) Mobile data is set to your eSIM line, not your home SIM. (2) Your home SIM has data roaming disabled as a backup protection. (3) Auto-switch or adaptive data routing is turned off. These three settings together prevent AT&T from charging through Tigo PY if your phone briefly loses the eSIM connection. Your home SIM stays enabled for calls and texts over WiFi. The eSIM handles all cellular data on Tigo PY at $5.49 for 1GB.
