Guernsey eSIM
Also covers Guernsey
Networks in Guernsey
A Crown Dependency, outside the EU rules and outside the UK's too
Guernsey is a Crown Dependency — not in the EU and not part of the United Kingdom — so neither roam-like-at-home nor a British domestic allowance covers it. Plans from both sides are full-rate roaming here, which surprises visitors from both.
Coverage on the island itself is good throughout, and the same applies to Alderney, Herm and Sark to a lesser degree.
The sea crossings are the gap: the ferries to Jersey, Sark and Saint-Malo lose signal mid-channel, and a phone near Jersey will sometimes register there instead, which is again a separate jurisdiction on the bill.
Guernsey eSIM: questions
When does the plan start counting?
From the first connection to a network in Guernsey, not from the moment you buy it. Install at home, activate after you land.
Do I get a phone number in Guernsey?
No. Plans here are data only: use messaging and calling apps over data.
Can I use it as a hotspot?
Yes. Hotspot is included, so a laptop or a second phone can share the data.
What if I run out of data?
Top up the same eSIM with another data plan, any time.
