Good question! Opting for a travel eSIM instead of roaming in Guernsey offers clear advantages:
Lower Costs: Say goodbye to outrageous roaming bills by switching to a local travel package designed for Guernsey.
Seamless Switching: Change between data plans without fumbling with physical SIM cards - perfect for spontaneous travellers.
Budget Control: Track data usage in real time and avoid surprise charges or overages.
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.
Yes! Our eSIMs cover more than 200 countries, including Guernsey. We even provide regional eSIMs that span multiple countries in one package - head over to our Travel eSIMs page to learn more.
Network & Data Issues: If your eSIM is refusing to work, check out our eSIM troubleshooting guide. For personalized help, send us a message and we’ll jump on it.
Installation Queries: Need a walkthrough on how to install? View our eSIM install tutorial - or drop us a line via our contact form.
General Support: Have something else in mind? Reach out here and we’ll handle it swiftly.
Yes, you can. Around 99 percent of our eSIMs allow quick and easy top ups through the ZenSim app. You can add more data, increase the days, or even include a different destination on the same eSIM right from the Zen Garden.
Open the app, go to the Zen Garden area, and you’ll see the top up button waiting for you.
Top up pricing: Guernsey top up plans follow the same pricing as on the website, minus a 10% discount.
Travelling for a while: If your trip lasts more than 30 days, you can queue multiple top ups. None of them will interrupt your current plan because each one only activates when the previous eSIM expires.
Travelling to more destinations: Most eSIMs let you attach extra countries via a top up. For example, if you're heading home from Europe and stopping in Singapore, you can add Singapore to your Europe eSIM and it will switch on once you arrive.
Single-country eSIMs like the Guernsey one are only valid within that country once activated.
For travel across borders, a regional plan might suit you better - our regional Travel eSIMs cover multiple countries in one.
Easy - once you have purchased your Guernsey eSIM, you will be able to access your unique referral URL. From there, simply share it with your people, and when they sign up (provided they're a new customer) you will both save A$5.
For each person you refer you will earn a A$5 voucher on your account which will be automatically applied to your next purchase and as we mentioned your referee will also save A$5 on their order.
The ZenSim app lets you track referrals and copy your referral URL anytime. See our terms for more information.
Great question! Our Guernsey unlimited plans come with a 3GB daily allowance, which is plenty for most travellers - the average person uses under 1GB a day.
If you do blow past that in a single day, your speed drops to 1Mbps until midnight, when your daily allowance resets and you're back to full speed.
If you're on a fixed-data plan instead (say 10GB or 20GB), there's no daily cap at all - use as much as you like until the plan runs out. We'll give you a heads up before that happens, and topping up is just a couple of taps away in the ZenSim app.
Your plan won't start using data or counting down days until you actually arrive in Guernsey - so there's zero risk in installing it early.
As long as you've already installed your eSIM, it'll automatically activate the moment you land, and that's when your days and data officially kick off.
From there, your eSIM expires when either your data or your days run out, whichever comes first (unless you're on an unlimited plan, in which case it's purely down to the days). So if you grab a 30-day plan, it'll run out 30 days after you arrive in Guernsey, not 30 days from when you bought it.
Easy way to check - just run your phone through our eSIM compatibility checker and you'll know in seconds whether it'll work with our Guernsey eSIM and networks.
Still not sure, or something looks off? Reach out to us and we'll sort it out. And if it turns out your phone genuinely can't run the eSIM, our refund policy has you covered with a full refund - so there's no risk in grabbing a plan and giving it a go.
You're covered - our 100% money back guarantee exists for exactly this situation.
Trip cancelled? Phone not eSIM-compatible? Plans changed and you just don't need it anymore? All of these are covered.
The full details sit in our refund policy, but in short: if you can't install or use the eSIM, we'll give you a full refund. You shouldn't have to pay for something you can't use.
