eSIM Guernsey
Guernsey from 7,95€ runs on the Sure network: 1 to 5 GB of data, prepaid and without a contract, set up from the QR code in your email — you are online the moment you step off the plane.
Your Selection
Your plan only starts counting when the eSIM first connects at your destination — so you can buy today and travel in three weeks.
How does Simbye eSIM work for Guernsey?
Set it up before you fly
Right after checkout you get an email with a one-click link and a QR code. Install the eSIM calmly at home on Wi-Fi; it takes a few minutes. That alone does not start the clock.
Switch it on when you arrive
Whether you land at Guernsey Airport at La Villiaze in the parish of Forest or sail into St Peter Port harbour: turn flight mode off, turn data roaming on for the new line, and you are on the Sure network. Only that first connection starts your days.
Get moving
The bus stop is about fifty metres beyond the arrivals exit and the taxi rank is right outside. From here your map, the taxi app, the bus timetable and the boat times all run on your own data instead of somebody else's Wi-Fi.
Check Device Compatibility
Make sure your device supports eSIM before purchasing
Which networks will you be on in Guernsey?
One network, nothing to configure: on Guernsey the eSIM connects to Sure by itself.
| Sure |
|---|
There is nothing to set up. On Guernsey the eSIM knows exactly one network — Sure — and connects to it on its own once you land. No access point, no code, no manual search. If nothing happens after a few minutes: toggle flight mode off and on, check that data roaming is switched on for the new line, and if needed pick Sure by hand in your network settings. Also make sure the new line is selected as your data connection, otherwise your old card keeps working in the background.
Sure covers Guernsey with 4G island-wide and also reaches Herm, Sark and Alderney, though coverage there cannot be promised. In St Peter Port, at the Bridge in St Sampson, around the airport at La Villiaze and along the west coast bays from Cobo through Vazon to L'Erée, reception is unremarkable in the best sense. It gets thinner where the island gets steep: in the wooded vaux, down in Petit Bot and Moulin Huet, in stretches of the southern cliff path, and inside old granite houses with thick walls. 5G is only just starting — the first sites went live in August 2026, with island-wide coverage announced for the end of 2026. So plan for 4G and treat anything faster as a bonus.
eSIM or a local SIM card in Guernsey?
Neither route asks for ID on Guernsey, so it comes down to time: the eSIM runs the moment you arrive, while a local card costs you a shop, its opening hours and change in notes the mainland rarely takes.
| Feature |  Simbye eSIM |
Local SIM card |
|---|---|---|
| Buying and setting up | At home before your flight, QR code arrives by email at once | Only after you arrive, in a shop on the island |
| ID required | No | Not on Guernsey either — the island asks for no registration for prepaid |
| Time after landing | Online the moment you step off the plane | First find somewhere that sells one, wait for opening hours, queue |
| Payment | Online by card in your own currency | In pounds on the island; Guernsey banknotes are not legal tender off-island |
| Your existing number | Stays active, WhatsApp carries on unchanged | A second number, and a card to fit into the phone or second slot |
| Local phone number | No, data only, no calls and no SMS | Yes, a +44 1481 number with calls and texts |
| Adding more data | Top up online any time, without going to a shop | Back to a shop or find a top-up voucher |
| If something goes wrong | Support by email, wherever you happen to be | Back to the shop, and only during opening hours |
For most travelers the eSIM is the simpler choice: set up before departure, no queuing on arrival.

Frequently Asked Questions about Guernsey eSIM
Data, calls, real phone numbers, top-ups and setup — everything you need to know before you buy a Simbye eSIM.
Yes, the eSIM works as soon as you land on Guernsey. You set it up before your flight using the link or QR code, and the moment you step off the plane it connects to the Sure network. Your days start with that first connection on the island, not when you buy.
Sure is the network you'll be on in Guernsey. Network selection is automatic — nothing to configure, no access point to type in. If nothing appears after landing: toggle flight mode, switch data roaming on for that line, and if needed choose Sure by hand in your network settings.
No, this plan doesn't also work on Jersey or in Britain. Guernsey, Jersey and Britain are three separate territories with their own networks. This eSIM is for Guernsey. If you travel on to Jersey or the mainland, you need a separate plan for that.
No, you don't have to register or show ID in Guernsey. Guernsey requires no registration and no identity document for prepaid mobile. You buy online, the QR code arrives by email, and that is the whole process.
Your home contract is so expensive on Guernsey because it's its own mobile territory with its own networks. Many providers bill the Channel Islands separately, often per megabyte or at a daily rate — and you only find out on the bill after the trip.
You can buy an eSIM for Guernsey online here, before you sail or fly over. Choose a plan from the table above, pay, and the QR code arrives by email within minutes. Scan it and the Guernsey profile is stored on your phone, ready to switch on when you reach the island. Nothing is posted to you.
An eSIM for Guernsey is a digital data plan that connects to the island's networks. Your phone connects through the island's partner networks, so you get a normal mobile connection in St Peter Port and around the coast without a local SIM card. You need an unlocked phone that supports eSIM, and you can install the profile before you leave home.
An eSIM for Guernsey starts at 7,95€; the exact cost then depends on how much data you take and how many days you stay, listed in the table above. A weekend needs far less than a fortnight, so the smaller bundles cost the least. You pay once, prepaid, before you travel.
How much data you need for Guernsey depends on your trip: a weekend of maps, WhatsApp and ferry timetables around St Peter Port stays under 1 GB. Stretch it to a week with photo uploads from Cobo, Vazon and Moulin Huet and 3 GB is comfortable. Streaming in the evening or a laptop on the hotspot is what takes you to 5 GB, which is the largest size on this page.
The eSIM that is best for Guernsey has nothing to compare on coverage: Guernsey has one network, Sure, and every eSIM here uses it. Sure carries 4G island-wide and reaches Herm, Sark and Alderney, though reception there varies, and it thins in the wooded vaux and down at Petit Bot. So pick on data and days. It stops at 5 GB and is data only, with no local number.
