Questions

Which networks does the Guernsey eSIM use?

Sure (5G). Coverage and speed depend on where you are.

Does the Guernsey eSIM work on 5G?

Yes, 5G on Sure. Your phone needs to support 5G; where there is no 5G signal, it uses 4G/LTE.

Will my phone work with the Guernsey eSIM?

Yes, if your phone supports eSIM and is not locked to one carrier. Most iPhones from the XS and XR onwards do, as do recent Samsung Galaxy and Google Pixel models. Check yours in our list of eSIM phones.

Does the Guernsey eSIM come with a phone number?

No. It is data only: no phone number, no calls or SMS. Your own SIM stays in your phone, so WhatsApp and iMessage keep working with your usual number.

How much data do I need for a week in Guernsey?

About 0.7 GB a day covers maps, messages, social media and some video, so around 5 GB for a week. Our pick for one week: 5 GB · 30 days for $16.59.

1 GB · 7 days for $5.19 is the lowest-priced plan. The lowest price per GB is 20 GB · 30 days at $1.89 per GB.

How long is the Guernsey eSIM valid?

Plans run for 7, 15 or 30 days.

When does my plan start?

When your phone first connects to a network in Guernsey, not when you buy or install the eSIM. So you can install it at home before you travel.

Is there an unlimited Guernsey eSIM?

No. Every plan has a fixed amount of data, up to 20 GB.

Can I use the Guernsey eSIM as a hotspot?

Yes, your phone can share the connection with a laptop or a second phone. Everything you share counts against your plan. Whether a network limits sharing depends on the plan, so ask us before you buy if it matters. More in our hotspot guide.

Can I top up my Guernsey eSIM?

Yes. Add data under My eSIMs while your plan is still valid. No new eSIM needed.

Why do some apps think I am in the United Kingdom?

Depending on the plan, your connection runs via the United Kingdom. Websites and apps, such as banking or streaming services, may then treat you as being there.

Can I get a refund?

eSIM purchases are final. If something isn’t right, write to us in Help and we’ll take care of it.
