How to activate your eSIM

An eSIM is a digital SIM card that's already built into your handset. So you no longer need a physical card. You can even order them in the My BASE app. That's especially handy, because we check your handset's compatibility and activate the eSIM in a few simple steps, so you can start calling, texting and browsing straight away. In other words, you no longer have to wait for your SIM card.

Note: eSIM is not available online for BASE Pro customers . Private customers can make use of eSIM, however.
