When's the ideal moment to activate my SouthESIM for my Latin American adventure?

Updated April 22, 2026

We recommend installing your SouthESIM on your device before you even board your flight. The beauty of SouthESIM is that your plan's validity period only kicks in when you arrive in your first covered country – perhaps Peru or Mexico – and connect to a local network like Movistar or Telcel. This means you can get everything set up in advance and enjoy instant connectivity the moment you land, ready to explore without a hitch!
