Argentina offers extraordinary value for mobile data due to the peso's weakness against the dollar. A 10 GB plan costs roughly $4 USD, making it one of the cheapest markets in South America. The catch: Ezeiza International Airport in Buenos Aires does not have reliable SIM card vendors. You need to buy in the city. Claro has the broadest national coverage and is the safest choice for travel beyond Buenos Aires. The Palermo, San Telmo, and Florida Street shopping areas in Buenos Aires all have Claro and Movistar stores. Passport registration is required but quick. For Patagonia travel, Claro covers El Calafate, Bariloche, and Ushuaia in town but not on hiking trails or in the national park interior.
Argentina has three main carriers: Claro (widest coverage, especially in Patagonia), Personal (Telecom Argentina), and Movistar. Ezeiza International Airport near Buenos Aires has carrier counters in the arrivals hall. Argentina's economy means prices fluctuate with the exchange rate, but data plans remain inexpensive in dollar terms.
eSIM for Argentina: the fastest option
Travel eSIMs skip the physical SIM process entirely. Buy online, scan a QR code, and your phone connects to a local network. No passport check, no airport queue, no SIM ejector tool. Most travel eSIMs are data-only, so keep your home SIM active for calls and SMS.
Local Claro SIM at Ezeiza Airport is the best value for multi-week Patagonia trips. eSIM is the better pick for short Buenos Aires visits or travelers connecting to Chile who want a single plan for both countries.

Where to buy a SIM card in Argentina
The best place to buy is Any Movistar, Claro, or Personal store in Buenos Aires. Airport availability is limited.. Here is what each channel offers and what to expect.
Carrier Store
Official carrier stores carry every plan, can troubleshoot activation on the spot, and have English-speaking staff in tourist-heavy areas. Prices match the carrier website.
Convenience Store
Convenience stores stock prepaid SIM cards near the checkout. Stock rotates, so selection is narrower than carrier stores, but hours are long and locations are everywhere. Bring your passport.
Buying experience
From Ezeiza Airport, take a taxi or Tienda Leon bus to Buenos Aires center. Claro has stores on Florida Street in the microcentro, open Monday through Saturday during business hours. You hand over your passport, fill in a short form, and the SIM is registered and activated in about 10 minutes. Top-up is through kioscos, small corner shops that are everywhere in Buenos Aires. You say "carga virtual" and the carrier name, hand over pesos, and the credit appears on your SIM within a minute. MercadoPago, the dominant Argentine payment app, can also top up if you have an account. Aeroparque, the domestic airport, occasionally has carrier kiosks but they are not reliable.

Real-world connectivity
Buenos Aires delivers consistent 4G from Claro and Movistar across the city. The Ruta Nacional 3 highway south toward Patagonia has coverage in towns like Bahia Blanca, Comodoro Rivadavia, and Rio Gallegos. Bariloche has solid 4G in town and around Lago Nahuel Huapi. The roads into Nahuel Huapi National Park lose signal within a few kilometers of Bariloche. El Calafate has good Claro 4G in town. The road to Glaciar Perito Moreno has coverage as far as the park entrance then drops. Ushuaia city has coverage. The Tierra del Fuego National Park has no signal on the trekking routes. El Chalten has weak Claro signal in the village only.
Our verdict on SIM cards in Argentina
Best for: Buenos Aires city travelers, Patagonia and glacier visitors, Wine region tourists in Mendoza.
Local Claro SIMs cost about $3-5 for 10 GB due to favorable exchange rates. eSIM costs more but saves the 15-minute registration at Ezeiza. For travelers combining Argentina with Chile, a regional eSIM plan is more practical than buying SIMs in both countries.
Activation & registration
Check your phone is unlocked
Your device must be carrier-unlocked to accept a Argentina SIM. Check Settings or contact your home carrier before you leave.
Choose a plan before you buy

Insert and configure
Insert the nano-SIM using the ejector tool. Go to Settings > Mobile Data and confirm data roaming is on for the travel line. Run a speed test to confirm you are connected.
