Coverage and network
Honest about coverage
Argentina mobile networks
Argentina's national figure is 68 Mbps, 69th in the world. Mendoza city and the main wine roads are covered well enough - but this is Andes country, and the high passes toward Aconcagua have long stretches with nothing.

Real Mendoza conditions
- City & Parque San Martín: Solid 4G/5G across central Mendoza, along Avenida Arístides, and around the park. Fine for maps, bookings and video calls.
- Maipú & Luján de Cuyo wineries: The closer wine regions have decent coverage, so bike-and-bodega days around Maipú hold signal.
- Uco Valley & the high Andes: Signal thins out in the Uco Valley and drops entirely on the Ruta 7 climb toward Aconcagua and the Chile border. Download your winery bookings and maps before heading up.
One eSIM, the whole country
Mendoza is just the start - this eSIM covers all of Argentina. Keep the same plan for Buenos Aires, Córdoba, or Bariloche.

Frequently asked questions
Where to buy a SIM card in Mendoza?
There are official Claro, Personal and Movistar stores in central Mendoza and in the Palmares shopping centre. Kiosk SIMs come unregistered and leave you to finish registration in Spanish from the handset. A travel eSIM like Ohayu avoids that - install before you fly and after landing it can connect you to supported networks like Claro, Personal or Movistar.
What ID do the shops here want?
A passport. Argentine lines must be registered to an identified holder, and a foreigner uses a passport in place of a DNI. Buy at an official operator store in central Mendoza rather than a kiosk - a kiosk SIM arrives unregistered and you finish the job yourself, in Spanish. A roaming plan sidesteps the whole errand.
Will it work at the wineries and in the Uco Valley?
Around Maipú and Luján de Cuyo, generally yes - those are close to the city and reasonably covered. The Uco Valley is patchier, and the high Andes routes toward Aconcagua and the Chilean border have long stretches with no signal from any carrier. Download maps and your bookings before heading out for the day.
Why isn't my eSIM working in Mendoza?
Up towards Aconcagua and the Chilean border there are long stretches with nothing. Failing that, the fix is usually in your SIM settings: Ohayu as the data line, roaming enabled, then an Airplane mode cycle. If that does not do it, chat and support@ohayu.com are open 24/7.
