Claro, Movistar and Personal compete nationwide; cities and Route 40 towns usually have 4G, while long Patagonian stretches and Andean passes can fade. Subway tunnels in Buenos Aires often kill signal until you surface. When you use NXTL in Argentina, your phone attaches to local networks such as Movistar, Personal, AMX/Claro; the live table on this page is the current list.
Setup takes minutes at home. For Argentina, install NXTL while you still have reliable Wi-Fi, keep your home line active for calls and bank texts, and switch on eSIM data when you land (for example via Ezeiza International (EZE)) so you can navigate straight to Buenos Aires. Top up later if you need more; unused balance stays yours.
Prepaid SIMs and eSIMs are sold at kiosks, subte stations and operator stores; foreigners register with a passport. Data-only tourist packs are common, though a local number helps with delivery apps. NXTL is the lower-friction option for most visitors to Argentina. You are not shopping for a SIM in Buenos Aires after a long flight — the eSIM is already on your phone, billed pay-as-you-go, with credit that carries to your next destination.
The reason travellers choose NXTL for Argentina — and for trips that do not stop there — is continuity. One eSIM, pay-as-you-go pricing, no expiry, and no new SIM when you leave Buenos Aires for the next country. Your leftover credit is still waiting.
Domestic flights between Buenos Aires, Córdoba and Mendoza are frequent, and you will want data working at provincial airports where Wi-Fi is slow or gated. That is where NXTL helps in Argentina: one eSIM ready before you arrive, billed only for the data you actually use.
