Travelling in Guernsey means moving between Saint Peter Port, Herm and Sark. Our eSIM keeps you connected across all of it, from landing to departure.
Network coverage in Guernsey
Coverage in Guernsey comes from Sure, giving you 5G where it is deployed and 4G everywhere else. Guernsey is outside the EU roaming zone and outside UK domestic plans, so a travel eSIM avoids surcharges.
How much data do you need?
Most travellers use between 500 MB and 1 GB a day for navigation, messaging and photos. Short city breaks fit comfortably in a fixed data pack; longer trips with heavy map use are cheaper on unlimited.

Setting up your Guernsey eSIM
Install the eSIM before departure and it stays inactive until it finds a network in Guernsey. Your home number keeps working alongside it, which matters for two-factor codes and boarding passes.
Whether you are in Guernsey for a long weekend, a work trip or several weeks on the road, the same eSIM covers it — you simply pick the amount of data that matches the length of the stay.
Prepaid, no contract and no deposit: a straightforward way to have mobile data in Guernsey from the moment you arrive.
