FAQ

Is an eSIM better than a local physical SIM card in Argentina?

Yes. Acquiring a physical prepaid SIM card in Argentina as a tourist can require visiting a local kiosk (kiosco) or mobile operator store, presenting your passport, and navigating potential language barriers. An eSIM allows you to download your profile and connect to local networks the moment your plane lands.

Can I top up my Argentina eSIM if I run out of data?

Yes, most major providers allow you to top up your data plan directly through their app or website. With HOLASIM, topping up is even easier because your installed eSIM never expires; you can keep the profile on your phone permanently and simply purchase new data packages whenever you return to Argentina or travel elsewhere.

Does my phone support eSIM?

Generally, most unlocked smartphones manufactured from 2018 onwards support eSIM technology. This includes Apple iPhone XR and newer, Google Pixel 3 and newer, and Samsung Galaxy S20 and newer. Always check your specific device settings to ensure eSIM capability before purchasing.
