Should I install my SouthESIM before I travel or once I arrive at the airport?

We strongly recommend installing your SouthESIM before you even head to the airport! Get it set up at home while you have a stable Wi-Fi connection and plenty of time. Airport Wi-Fi can be notoriously slow, unreliable, or require fiddly registration, which is the last thing you want after a long flight. Remember, your SouthESIM plan only activates once it connects to a local network in your destination, so installing it early won't eat into your validity. This way, you're connected the moment you land, ready for your adventure!
