Super easy. Bought and installed prior to travel, and as soon as we landed it was simple to turn on, get mobile data to work and it found service immediately. Great to have internet to aid travel and new places.

This is my second time buying an Esim card. Everything works great, the installation on Android was quick, the internet works well, and calls and text messages are working. You can also register the SIM card yourself online with your passport. So there's no need to buy a SIM card at the airport or go to a store.
