Traveller's guide

Staying connected in Guernsey — what to know

This Channel Island is small and well covered — reliable signal from St. Peter Port around the cliff paths and bays.

The Channel Islands are outside the EU and the UK's domestic zone, so a dedicated eSIM avoids surprise roaming.

FAQ

Questions, answered

Will the Guernsey eSIM work on my phone?+
Yes, as long as your phone supports eSIM and is carrier-unlocked. That covers iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and most modern Android phones. Dial *#06# to check for an EID number.
How fast is the data in Guernsey?+
Your eSIM connects to the strongest available local networks at 4G speeds — fast enough for maps, video calls, streaming, social media and mobile hotspot.
Do I need a passport or registration?+
No. There's no ID check, no paperwork and no SIM registration. You buy online, receive a QR code by email, and install it yourself in under two minutes.
When does my plan start?+
Validity begins the moment your eSIM first connects to a network in Guernsey — not at purchase. You can install it days ahead of your trip with zero waste.
Can I top up if I run out of data?+
Yes. Add more data to the same eSIM in seconds from your account — no new QR code and no reinstall needed.
Can I keep my normal number for calls and texts?+
Yes. The eSIM runs alongside your physical SIM, so your home number stays active for calls and bank codes while the eSIM handles data in Guernsey.
What happens when my data runs out?+
Your connection simply pauses — no surprise bills, ever. Just top up to keep going, or buy a fresh package.
Can I use it as a mobile hotspot?+
Yes, tethering and hotspot are included, so you can share your connection with a laptop or a travel companion's phone.
