Prepaid SIM Card & eSIM for Argentina (2026 Guide)

Yes — Ezeiza (EZE) has SIM counters from local carriers. Airport SIMs from local carriers cost around $5-10 for 5-10GB / 28 days. The counter is in the arrivals hall after customs. A prepaid eSIM is a better option: purchase before departure, scan the QR code on the plane, and connect the moment you land for $4.49 (1GB). No waiting in queues or dealing with staff language barriers.

Yes. DNI or passport required This applies to physical SIM cards purchased at airports and phone shops. A prepaid eSIM purchased online from an international provider activates via QR code — no in-person passport scan required. You complete the process from your phone before departure. This is the main practical advantage of eSIM for Argentina: it bypasses the local ID registration requirement entirely.

A prepaid eSIM saves money on every front. Airport SIMs at Ezeiza (EZE) run $5-10 for 5-10GB / 28 days, and that price often includes less data than a comparable eSIM plan. A prepaid eSIM starts at $4.49 for 1GB — the 20GB plan at $41.99 drops to $2.10/GB. Factor in the 15-25 minutes saved by not standing in an airport queue, and the eSIM wins on both cost and time for Argentina.

Yes. You can scan the QR code over home WiFi up to 30 days before your flight. Open your phone's eSIM settings, scan the code, and leave the plan inactive until you land in Argentina. The night before departure is the sweet spot — your home network is fast, support is reachable if anything goes wrong, and you board with everything ready. Validity starts from first use in Argentina, not the purchase date. Plans start at $4.49.

Apple removed the SIM tray from iPhone 14 US models, and Samsung followed on select Galaxy models. The industry is moving toward eSIM-only devices. Current compatibility: iPhone XS (2018)+, Samsung Galaxy S20 (2020)+, Google Pixel 3 (2018)+, and most 2020+ flagships. The critical check is carrier-unlock status — not the model. A carrier-locked iPhone 16 cannot use a Argentina eSIM. Verify in Settings > General > About (look for "No SIM restrictions") before purchasing any travel plan.

Yes — tethering works on most Argentina eSIM plans. Battery drain is the hidden cost: running a hotspot cuts your phone's battery life roughly in half. Carry a power bank if you plan to tether for more than an hour. Data consumption also doubles or triples compared to phone-only use. A 1-hour video call over hotspot uses 1-2GB. Airalo allows hotspot on most plans; Holafly caps daily hotspot at 1GB. Check provider terms before buying a plan for Argentina.

Data stops. No overages, no hidden fees. Budget travelers visiting Argentina can use this to their advantage: buy the smallest plan as a test run. If coverage and speed meet your needs, top up with a larger plan through the app over WiFi. This approach costs slightly more per GB than buying large upfront, but it limits risk if the provider's Argentina coverage disappoints. Top-ups take about 2 minutes and do not require a new QR code scan.

Yes — and keeping your home SIM active is important for SMS verification codes. Banks, email providers, and two-factor authentication systems send codes to your home number. With both SIMs active, those codes arrive normally in Argentina. Route all data through the travel eSIM and leave your home SIM on for calls and SMS only. Your home carrier charges standard rates for incoming SMS (usually free). No app reconfiguration needed.

Buying at the gate works if you have WiFi access — most airports offer free terminal WiFi. The install takes under 5 minutes once the QR code arrives in your email. The risk with last-minute purchasing is support availability: if the QR code does not scan or the provider's app has a login issue, you have minutes, not hours, to fix it. One to two days before departure removes that risk entirely. Plan validity starts from first use in Argentina, so buying early is never wasted. Plans start at $4.49.

Yes. After installation, the eSIM connects to Claro AR's cellular network in Argentina without WiFi. The landing sequence is simple: turn off airplane mode, make sure the Argentina eSIM is toggled on in your cellular settings, and wait 30-60 seconds for the phone to find a local tower. No WiFi needed at the airport, on the tarmac, or anywhere else. WiFi is only required for the one-time QR code scan during initial setup at home.

iPhones store up to 8 eSIM profiles at once, with 2 active simultaneously (iPhone 13 and newer). You can install your Argentina travel eSIM alongside your home eSIM and toggle between them in Settings > Cellular. No need to delete one to add another. The iPhone 14 US models are eSIM-only, so dual eSIM is the standard setup for those devices. Switching the active data line takes about 5 seconds — tap the profile name and confirm.

Go to Settings > General > About (iPhone) or Settings > Connections > SIM Manager (Samsung). If you see an option to add an eSIM or cellular plan, your phone supports it. To check carrier unlock status, insert a SIM from a different carrier — if it connects, your phone is unlocked. You can also call your carrier and ask directly. A locked phone will reject any foreign eSIM profile, including plans for Argentina.
