We highly recommend scanning and installing your SouthESIM at home before you even leave for your trip. This way, your eSIM profile is ready to go. The moment you land at Mexico City (MEX) or Bangkok (BKK) Airport, you can simply switch it on and instantly connect to the internet. No fumbling for airport Wi-Fi or worrying about connectivity right after a long flight – just seamless data from the get-go!
