Frequently Asked Questions about the Guernsey eSIM
Everything you need to know about the Guernsey eSIM.
01When does my data plan start?
This plan's days start when the eSIM first connects to a network in its coverage area, not when you buy or install it. Some other Guernsey plans start differently. Each plan's page shows its rule under Activation.
02Can I make phone calls and send messages with the eSIM?
Most Guernsey plans are data-only, with no phone number for calls or texts. Plans marked Call include a phone number, call minutes and text messages (SMS). On a data-only plan you can still call and message over apps like WhatsApp.
03When will I receive my eSIM?
Once you purchase an eSIM, you will receive it immediately to your email address. You then scan the QR code to install the eSIM. If you have not installed, activated or used your eSIM, you can ask us to review a refund within 30 calendar days of purchase, when the order is linked to your Roamify account email. See our refund policy for more information.
04Can I keep my WhatsApp number?
You don't need to do anything to keep your WhatsApp number. You'll automatically keep your number, contacts and conversations.
05What is the network speed of the eSIM?
The Roamify eSIM offers maximum speed coverage. But bear in mind that in some areas of limited coverage there may be a lower speed connection.
06Do I have to activate data roaming on my device?
Yes. To ensure that your eSIM gets the best coverage, you must turn on data roaming on your mobile settings. This will not incur any additional charges, as long as you have already set up the eSIM.
07Will my eSIM have a local IP address in Guernsey?
Not always. This plan connects through a roaming partner, so websites and apps may see an IP address registered in another country rather than in Guernsey. This is normal for travel eSIMs and does not change your data allowance, speed or coverage. If a service requires a local IP address, such as some banking apps or regional streaming catalogues, connect through a local network or use a VPN set to Guernsey.
08What do I do if I delete or lose my eSIM's QR code?
If you cannot find the code, please contact our 24/7 customer support team at support@getroamify.com or our online chat function. We will resend the code to your email.
09What happens if I use up my data or my days of validity?
On Guernsey Unlimited plans, full speed lasts up to 1 GB, then data is slowed to 5 Mbps, not cut off. On Guernsey plans with a fixed amount of data, data stops or is slowed once it is used up, depending on the plan. Some of them can be topped up with more data. Each plan's page shows its rule under Fair use policy. When the plan's days run out, your eSIM stops working and you lose its internet connection.
10What eSIM data plan should I choose for Guernsey?
You can choose variable plans as shown above. You can contact us at any time if you're not sure which plan is best for you.
11Will the connection speed be reduced?
On Guernsey Unlimited plans, full speed lasts up to 1 GB, then data is slowed to 5 Mbps, not cut off. If your connection seems slower than that, contact us by chat and we will check it.
12Can I renew or extend the data on my eSIM?
Yes, you can do so by logging into your customer panel on the Roamify website. You will find the data plans you can purchase there. Once you've made your purchase, it will be activated immediately on the eSIM you have linked.
13Can I share data with other devices?
Yes, you can share data with other devices. You can do this by activating the hotspot on your device.
14How do I set up the eSIM on my device?
Once you make your purchase, we will send you an email with precise instructions to install your eSIM in two ways: by scanning the QR code or by copying and pasting the manual installation codes. To install with the first option, it is essential that the QR code is printed or on another device. Otherwise, you can follow the manual installation instructions for your Roamify eSIM. If your device is iOS, go to Settings → Cellular → Add eSIM and scan the QR code or paste the manual installation codes sent to your email. Then follow the on-screen instructions and choose your new eSIM as the line for mobile data. If your plan includes calls or texts, choose the Roamify eSIM as the line for those too. On a data-only plan, keep your physical SIM as the line for calls and texts. If your device is Android, follow the instructions we will email you to install your Roamify eSIM. When you are in Guernsey, select your Roamify eSIM for mobile data and turn on data roaming for it. At Roamify, we want to make setting up your eSIM as easy as possible. For this reason, all our eSIM products come with complete instructions for easy setup. If you have any questions or need help, don't hesitate to contact our customer support team. We will be there for you 24/7.
15When should I set up my eSIM?
You can install this plan a day or two before you travel, over Wi-Fi. Its days start only when it first connects to a network in its coverage area. When you are in Guernsey, select the Roamify eSIM for mobile data and turn on data roaming for it. An installed eSIM is generally no longer refundable. See our refund policy.
16How can I check how much data I have left?
To check your remaining data, log in to our web app with the access details we emailed you when you made your purchase. You can also check your data use in your device's mobile data settings.
17How many times can I use my eSIM card?
Your eSIM can only be activated on one device. If you delete the eSIM from your device, you will not be able to reuse it. You cannot scan the QR code on two devices.
18How can I delete the Roamify eSIM once I've used my data?
You don't need to delete the eSIM. But if you want to, please see how to delete eSIM on iOS and Android.
19Can I use my (physical) SIM card and Roamify eSIM at the same time?
Yes. Choose the Roamify eSIM as the line for mobile data in your device settings. On a data-only plan, keep your physical SIM for calls and texts; if your plan includes calls or texts, choose the Roamify eSIM as the line for those too. If data roaming stays on for your physical SIM, your home network provider may charge roaming fees, so turn it off for that line.
20How do I get a refund?
Most unused eSIM purchases are eligible for a refund review when you send your request within 30 calendar days of purchase. To qualify, the eSIM must not be activated, installed, or consumed, and the order must be linked to your Roamify account email. Once an eSIM has been activated or installed, or has recorded data usage, it generally cannot be refunded. Please see our eSIM Refund Policy for the full terms.
21Which eSIM carrier will I connect to in Guernsey
Roamify's Guernsey eSIM connects to Sure Mobile, as listed for every plan on this page.

Connectivity on the Cliff Paths of Guernsey
Guernsey offers a unique blend of picturesque trails and quaint towns. As you meander along the cliff paths above St Peter Port, the island's capital, you'll enjoy breathtaking views of the English Channel. Visits often include a boat trip to the tranquil island of Herm, or a stroll through St Sampson and Castel. Staying connected here means balancing between nature's serenity and modern convenience.
Mobile connectivity in Guernsey is remarkably good in urban areas like St Peter Port, where most travellers find themselves starting their journey. However, as you venture onto the cliff paths or take the boat to Herm, service can become spotty. The high cliffs and remote parts of the island are scenic but can sometimes challenge a stable connection.
To make the most of your trip, ensure your eSIM is set up before you land on the island. Download maps and any important documents you might need while you're still in a well-covered area. Upon arrival, you can expect reliable service in populous areas, which will help you stay connected as you explore Guernsey's charming towns and stunning coastlines.
Using an eSIM in Guernsey
Answers to the questions travellers actually ask about staying connected in Guernsey.
Is it possible to switch between Guernsey networks manually if my eSIM signal is weak?
Our Guernsey plans list Sure Mobile as their network, so a weak signal comes down to where Sure Mobile reaches. First make sure the phone is not the cause: airplane mode off, the Roamify eSIM on and set for mobile data, and data roaming on for it. Restart, and if data still does not come back, contact our 24/7 support team by chat or at support@getroamify.com.
