Guernsey is a British Crown Dependency in the English Channel, and its Bailiwick also includes the smaller islands of Alderney, Sark and Herm. It is part of neither the United Kingdom nor the EU. Sure, which took over Airtel-Vodafone at the end of 2024, is the largest operator, and JT is the other main player. Our Guernsey eSIM runs on the Sure network, with 4G in St Peter Port and across most of the island. Networks: Sure.
For a long weekend, 1 GB for 7 days is enough for maps, messaging and a few photos. Staying a week or longer? Choose 3 or 5 GB, each valid for 30 days.
Guernsey sits outside the EU roaming rules, so whether your home plan covers it depends on your operator. Check before you travel.

Yes. Our eSIM gives you instant mobile data in Guernsey on the local networks, with no roaming fees. Your phone needs to support eSIM and be carrier-unlocked.
It depends on your trip. For mostly maps and messaging, 1 to 3 GB is plenty. If you use navigation, social media and some streaming, plan for roughly 1 GB every two to three days.
Right after payment. You receive a QR code on screen and by email immediately. It is best to install it at home over Wi-Fi before you leave.
Yes. Your own SIM stays in your phone for calls and texts. The eSIM runs alongside it, purely for mobile data in Guernsey.
The cheapest eSIM for Guernsey at esimzu starts from €4,49, with a lowest-price guarantee. You pay in euros by Bancontact, card or crypto and receive the eSIM instantly by QR code, with no app or physical SIM card.
Not by law. Guernsey is not in the EU, so the EU roam-like-at-home rules do not apply there. Some European operators still include it in their Europe zone, while others treat it as a non-EU destination. Check your home plan before you travel, or use an eSIM so you know your data allowance in advance.
The eSIM works wherever the Sure network has signal. Alderney and Sark also have mobile masts, but coverage there is thinner than on Guernsey itself, especially on Sark with its cliffs. Download an offline map before a day trip.
No, this eSIM is meant for Guernsey. Jersey is a separate Crown Dependency and is not included in this plan. If you visit both islands, add a Jersey eSIM or choose a Europe plan that lists both Guernsey and Jersey among its destinations.
Expect 4G, as our Guernsey plans run on 3G and 4G. That is more than enough for navigation, messaging and video calls.
