Guernsey travel data eSIM
What is a Guernsey eSIM?
A Guernsey eSIM lets you arrive on the island with data ready to go. Install the profile at home, then when you land in Saint Peter Port your phone will connect to the local network and you can browse, map routes, and check ferry times without swapping SIMs. It’s a data‑only plan that works on any unlocked eSIM‑compatible device, keeping your home number untouched while you explore the Channel Islands.
In Guernsey the eSIM links to Sure 5G’s network, giving you access to the operator’s mobile data services for the duration of your chosen plan. Your data allowance starts counting from the first connection made on the island, and you can use it for navigation, messaging apps, and online bookings while you move between towns and islands.
Local networks
Which networks you connect to in Guernsey
When you activate the eSIM in Guernsey it connects to Sure 5G’s infrastructure. The actual reach of service depends on the operator’s network in each area you visit, so you’ll have mobile data wherever the operator’s towers are present. This enables you to pull up maps, check transport schedules, and stay in touch while traveling around the island.
4 plans are available for Guernsey, from $6.90 up to $67.90. Every plan is data only, delivered by QR code, and starts counting when you connect on arrival.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which operator does the Guernsey eSIM use and what does that mean for a traveller?
The eSIM connects to Sure 5G’s network. For travellers this provides access to the operator’s mobile data services, allowing you to browse, use apps, and access online information while you are on the island.
Does the Guernsey eSIM also work in a real neighbouring country of Guernsey?
It is a single‑country plan valid only in Guernsey. If you need coverage in nearby France or the United Kingdom, regional multi‑country plans are available separately.
Which plan size suits a trip to Saint Peter Port and Vale?
As a rough guide, the 3 GB 30‑day plan often covers a short stay visiting two towns, while the 5 GB option provides extra allowance for heavier use such as streaming maps or video calls.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
