This makes it the most convenient way to stay connected while exploring Guernsey's beautiful coastline and attractions.

Most modern smartphones support eSIM technology, including iPhone XS and newer, Samsung Galaxy S20 and later, and Google Pixel 3 and above.

You can usually verify this by navigating to your phone's cellular or mobile data settings and looking for an option to add a digital SIM plan.

An eSIM travel plan typically offers several gigabytes of data for a fraction of that cost, with prices starting as low as a few dollars per day.
