Does EU roaming cover Guernsey for travelers?
HelloRoam is the highest 2026 composite scorer at 4.64/5 on our rubric for Guernsey. EU roaming applies inside EU member states for European carrier customers. If Guernsey is in the EU, a home plan can use its allowance without a surcharge, but fair-use rules still cap daily volume and speed.

HelloRoam prices fixed data from $3.50/GB and unlimited from $5, with a 180-day refund. Holafly also sells unlimited from $2.99/day. For stays over 5 days or above 3GB per day, the eSIM path is the cleaner comparison.
