Yes. Movistar has the strongest coverage in Ushuaia and along the Beagle Channel. The city center and port area have reliable 4G. Tierra del Fuego National Park trails and Route 3 toward the Chilean border lose signal in valleys — download offline maps before heading out.

Yes. The Argentine side visitor center and main walkways have 4G coverage. Trails closer to Garganta del Diablo drop to LTE-only, and some viewpoints deep in the forest lose signal entirely. The Brazilian side (Foz do Iguaçu) is a different country — your Argentina eSIM will not work there unless it includes Brazil coverage.

Plan for 1–2 GB per day if you use Google Maps heavily, upload photos to Instagram, and make WhatsApp calls. A week-long trip with daily navigation, social media, and rideshare apps will consume 7–12 GB. If you are streaming video or working remotely, double that estimate.

Yes. Both apps work on the eSIM's Argentine phone number. Uber operates in Buenos Aires, Mendoza, and Córdoba. Cabify has wider coverage including Rosario and some Patagonian cities. The eSIM provides the live data and local number both apps need for driver coordination.

Yes. WhatsApp voice and video calls run over data, so as long as you have signal the calls work normally. Most Argentines use WhatsApp for everything — restaurant bookings, hostel questions, even coordinating with tour guides — so expect to rely on it daily.

Movistar dominates Bariloche and the surrounding lakes district — Circuito Chico, Villa La Angostura, and Llao Llao all run on Movistar 4G. Personal covers the town center but thins quickly on mountain roads and ski areas. The eSIM will hand off to whichever network is stronger at your location.

Partially. The Pampas stretch from Buenos Aires to around Bahía Blanca has cell coverage. La Pampa province — roughly the middle third of the route — goes offline on all carriers. Coverage returns as you approach Neuquén and Bariloche. Download offline maps, podcasts, and shows before boarding.

Yes. MercadoLibre (shopping and payments) works fine on a foreign-issued eSIM. The app needs live data and an Argentine phone number for order tracking and delivery coordination; the eSIM provides both. You will still need an Argentine bank card or Mercado Pago account to complete purchases.

Yes. PedidosYa (food delivery) requires live data and an Argentine phone number for driver coordination. The eSIM gives you both. You can use a foreign credit card in the app, but some restaurants require cash on delivery — confirm payment method before ordering.

The eSIM costs less and activates faster. Airport kiosks sell Personal and Claro SIMs at tourist markup, usually 30–50 percent above street price, and the peso price changes weekly with inflation. The eSIM locks your cost in USD or EUR when you buy. Installation is two minutes before your flight; a physical SIM means queuing at the kiosk, filling a form, and waiting for activation.

Intermittently. The boardwalks facing the glacier have patchy 4G — enough to send time-stamped photos when the ice calves, but not reliable for video calls or streaming. The parking lot and visitor center have stronger signal. Offline maps are essential for the drive from El Calafate.

Roughly 100–200 MB per day for active navigation — more if you reroute frequently or explore multiple neighborhoods. Long-distance drives like Buenos Aires to Mendoza or the Ruta 40 in Patagonia will use more because the app recalculates as coverage drops and returns. Download offline map tiles for your route to cut data use by half.

Yes. The city of Mendoza and wine-country roads around Maipú and Luján de Cuyo have reliable 4G on all three carriers. Coverage thins in the Andes foothills and on Route 7 toward Chile — expect dead zones above 2,500 meters. Download offline maps before any mountain drive or Aconcagua trek.

Yes. Hotspot is enabled by default with no throttling on the first several gigabytes. Useful if you are working remotely between hikes or traveling with a partner whose phone does not support eSIM. Check your plan's total data allowance — video calls and cloud uploads consume data quickly.

Yes. El Calafate town has 4G coverage on Movistar and Claro. The drive to Glaciar Perito Moreno (80 km) has intermittent signal — coverage drops in valleys and returns near the park entrance. The glacier boardwalks have patchy 4G, enough for photos but not streaming. Download offline maps before leaving town.
