Prepaid Data Plans for Guernsey
esimbloom lists 14 prepaid eSIM plans for Guernsey from $3.84 (the smallest is 500MB for 1 day). Every plan is data-only — mobile internet for maps, messaging and bookings, but no local phone number or SMS — and prepaid: pay once, no contract, no roaming charges.
Choose the data allowance and validity period that matches your trip. Once you complete your purchase, your eSIM QR code arrives by email within minutes. You can install it before you leave home and activate it the moment you land in Guernsey.
How to Set Up Your Guernsey eSIM
Before you travel, check that your phone is carrier-unlocked and eSIM-compatible. Install the eSIM by scanning the QR code in your email under Settings, then label it clearly so you can identify it as your Guernsey data plan. Keep your home SIM active for calls and texts if needed.
Activate the eSIM data plan when you arrive in Guernsey by enabling the data line in your phone settings. Your device will register on the network automatically. You can monitor your data usage in settings and top up by purchasing another plan if you run through your allowance early.
Staying Connected in Guernsey
Guernsey is compact and well-covered. St Peter Port, the main town, along with the coastal parishes and inland lanes all have reliable mobile connectivity. Travellers using data for maps, ride apps, and restaurant lookups typically consume between 500MB and 1GB per week, though video calls and streaming will increase that.
If you are island-hopping to Herm or Sark by ferry, expect limited or no mobile signal on the smaller islands. Download offline maps and any ferry schedules before you leave St Peter Port. Rural cliff paths and beaches on Guernsey's south coast generally maintain coverage, but it is wise to cache directions before heading out for coastal walks.
Frequently asked questions
How much does an eSIM for Guernsey cost?
esimbloom Guernsey eSIM plans start at $3.84, with 14 plans to choose from. You pay once for the plan you pick — no roaming fees and no contract.
Do I need an eSIM for Guernsey?
Only if you want mobile data without roaming charges. An esimbloom Guernsey eSIM is installed from a QR code before you fly, activates on your first connection in Guernsey, and is data-only — your home SIM stays in the second slot for calls and SMS, with its data roaming switched off.
Do I get a Guernsey phone number with this eSIM?
No. esimbloom plans are data-only, so you will not receive a local phone number, SMS, or voice calling. Use WhatsApp, iMessage, or similar apps over your data connection for messaging and calls.
When should I activate my Guernsey eSIM?
Install the eSIM profile before you travel, but wait to activate data until you land in Guernsey. Your validity period starts the moment the eSIM registers on the network, so activating early wastes days.
Will the eSIM work on Herm and Sark?
Coverage on Herm and Sark is limited or absent. The eSIM works across Guernsey itself, but you should not rely on mobile data once you leave the main island by ferry.
Can I use my Guernsey eSIM in the UK or France?
No. The plans sold for Guernsey are valid only in Guernsey. If you are visiting Jersey, the UK mainland, or France on the same trip, you will need separate eSIM plans for those destinations.
How much data do I need for a week in Guernsey?
For maps, web browsing, and messaging, 1GB covers a week for most travellers. Add extra data if you plan to video call, upload photos in real time, or stream music while exploring the island.
