Questions fréquentes

Will a UK plan cover Guernsey?+

Do not assume it will. Guernsey is a Crown Dependency separate from the UK and outside the EU, so it is usually listed on its own or grouped as the Channel Islands. Check the destination list before buying, and if you plan to cross to Sark or Alderney, make sure the whole island group is included.

Can I do Sark as a day trip?+

Yes, if the weather cooperates. The boat from St Peter Port takes about forty-five minutes with several sailings in season. There are no cars, so you walk, cycle or take a horse cart. Confirm the return sailing before you go across, because rough seas can cancel it and leave you looking for a bed for the night.

When is the best time to visit Guernsey?+

May to September is when the boats to the smaller islands run in full and the cliff paths are at their best. Out of season many services drop to reduced timetables or stop, some restaurants close, and crossings are cancelled by wind more often, so build a fallback plan into the trip if you go then.

When does a Guernsey eSIM start counting days?+

Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.

Do I have to remove my home SIM?+

No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
