Staying connected while traveling internationally no longer requires swapping SIM cards or risking expensive roaming fees. Thanks to eSIM technology, travelers can activate mobile data digitally - often before they even leave home.

What is an eSIM?

An eSIM is a built-in digital SIM card that allows you to download a mobile data plan directly to your phone. There's no physical SIM to insert or remove, making it ideal for international travel.

Why travelers use eSIMs:

• Activate in minutes

Most modern smartphones - including new iPhones, Google Pixels, and Samsung Galaxy devices - support eSIMs.
