Of course, you're familiar with SIM cards – those tiny chips you insert into your phone to connect to a cellular network. An eSIM (electronic SIM) functions much the same way, but it's integrated into your device, serving as a virtual SIM card.

With an eSIM, there is no need to swap out SIM cards physically. You can easily activate your eSIM by tapping a button in the StaffTraveler eSIM app. This means you can connect to the internet while traveling abroad without worrying about finding a local SIM card or dealing with expensive roaming charges.

An eSIM is like having a portable, virtual SIM card that makes staying connected while traveling easier and more convenient. 

It is essential to check that your device is compatible with an eSIM. Even though the technology has been around for a while, not all devices, even newer ones, support it.

If your device supports eSIM, all you need to do is load up a StaffTraveler eSIM, and you'll be using data around the world like a Pro!
