Guernsey eSIM FAQs
Your eSIM will activate automatically when you land in Guernsey. However, we recommend installing the Guernsey Travel eSIM beforehand (activation happens on arrival).
Simply scan the QR code provided or install the eSIM via the ZenSim app while on WiFi. Once you touch down in Guernsey, the eSIM will go live.
Trouble activating? See our eSIM Troubleshooting Guide or contact us for help ☺️
No, these eSIMs only provide data access and do not assign you a phone number. To make calls, please use internet - enabled apps such as WhatsApp or FaceTime.
Absolutely! ZenSim’s eSIMs work in over 200 countries, and Guernsey is one of them. We also have regional eSIMs that cover several nations on a single plan - check out our Travel eSIMs page for details.
Once activated in Guernsey, your eSIM typically won’t function outside that country.
If you're planning to hop between countries, we recommend checking out our regional Travel eSIMs - they’re made for multi-country use and cover most major regions.
Yes it can. Nearly all ZenSim eSIMs support top ups inside the app. You can boost your data, add extra days, or attach a new country to the same eSIM from the Zen Garden in only a few steps.
Just log into the app, open the Zen Garden, and you’ll find the top up control ready to use.
If you're travelling longer than 30 days, you can purchase multiple top ups in advance. They only activate once the current plan finishes, so nothing overwrites your existing eSIM.
If your trip includes several destinations, many of our eSIMs support multi country top ups. For example, you can add Dubai to a Europe eSIM and it will activate the moment you arrive without reinstalling anything.
Absolutely - using a travel eSIM beats roaming in Guernsey for several reasons:
Cost Efficiency: Our Guernsey local data rates are much cheaper than pay-as-you-go roaming fees.
Instant Activation: No need to wait for a SIM card; your eSIM goes live as soon as you land.
Data Visibility: Monitor exactly how much you’ve consumed, so there are no hidden surprises on your bill.
Not until you land in Guernsey. Installing ahead won’t start your plan; it goes live automatically when you arrive.
Make sure to install before you travel, as WiFi is required for setup and this way your Guernsey eSIM will be ready to use when you land.
If you encounter connection issues, see our eSIM Troubleshooting Guide or contact support.
Traditional calls and SMS aren’t part of our Guernsey eSIM packages - they’re strictly data provision. To talk or text, use internet - based services (WhatsApp, Signal, etc.) with your eSIM data.
Once you arrive in Guernsey, your eSIM activates automatically if it’s already installed.
If you install it after arriving, the eSIM will activate and begin working immediately.
For any setup or connection problems, refer to our eSIM Troubleshooting Guide or contact our support.
Connectivity Troubleshooting: Check our troubleshooting guide if your eSIM won’t connect. Still stuck? Hit up our support team and we’ll get you back online fast.
eSIM Installation Help: For help setting up your eSIM, visit our installation guide, or simply contact us - we’re happy to assist.
Other Inquiries: Have another issue? Head to our contact page and we’ll respond ASAP.
Yes! You may install the Guernsey eSIM up to 30 days before you travel. It won’t connect or start using data until you arrive.
Early installation ensures you’re ready on arrival, and it won’t drain your plan until you’re in Guernsey.
If you encounter an activation message on iPhone before landing, it’s usually safe to ignore - see our eSIM Troubleshooting Guide for more info.
