Frequently Asked Questions about the United Kingdom eSIM

Everything you need to know about the United Kingdom eSIM.

01

When 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 United Kingdom plans start differently. Each plan's page shows its rule under Activation.

02

Can I make phone calls and send messages with the eSIM?

This United Kingdom plan is data-only, so it has no phone number for calls or texts. Some other United Kingdom plans include calls, so choose one of those if you need a number. On a data-only plan you can still call over apps like WhatsApp.

03

When 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.

04

Can 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.

05

What 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.

06

Do 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.

07

Will my eSIM have a local IP address in United Kingdom?

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 United Kingdom. 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 United Kingdom.

08

What 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.

09

What happens if I use up my data or my days of validity?

Full speed up to 1 GB, then reduced to 5 Mbps. Your data is slowed, not cut off. When the plan's days run out, your eSIM stops working and you lose its internet connection.

10

What eSIM data plan should I choose for United Kingdom?

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.

11

Will the connection speed be reduced?

Full speed up to 1 GB, then reduced to 5 Mbps. Your data is slowed, not cut off. If your connection seems slower than that, contact us by chat and we will check it.

12

Can I renew or extend the data on my eSIM?

Plans for United Kingdom can't be topped up. When your data or validity runs out, buy a new United Kingdom plan on the Roamify website or app. It comes as a new eSIM, which you can install alongside the old one.

13

Can 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.

14

How 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. Your United Kingdom plan is data-only, so 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 United Kingdom, 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.

15

When 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 United Kingdom, select the Roamify eSIM for mobile data and turn on data roaming for it. Some United Kingdom plans must be installed in United Kingdom. Their page says so. An installed eSIM is generally no longer refundable. See our refund policy.

16

How 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.

17

How 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.

18

How 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.

19

Can I use my (physical) SIM card and Roamify eSIM at the same time?

Yes. Keep your physical SIM for calls and texts, and choose the Roamify eSIM as the line for mobile data in your device settings. If data roaming stays on for your physical SIM, your home network provider may charge roaming fees, so turn it off for that line.

20

How 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.

21

Which eSIM carrier will I connect to in United Kingdom

Roamify's United Kingdom eSIM connects to O2 (UK), EE, as listed for every plan on this page.

Seamless Stays from London to the Highlands

The United Kingdom offers a rich tapestry of urban and rural experiences unlike anywhere else. Picture yourself walking the historic Royal Mile during Edinburgh's festival season, taking in performances that spill into the streets. Or imagine boarding the iconic sleeper train from bustling London northwards, awakening to the rugged beauty of the Scottish Highlands. Whether you're navigating the intricate Tube network deep beneath central London or meandering through Manchester's vibrant streets, having a reliable connection keeps you in sync with your surroundings.

In major cities like London, Edinburgh, and Manchester, mobile connectivity is robust, allowing for easy streaming and navigation. However, as you venture into the Highlands or the more remote parts of Wales, you might find the signal becomes more sparse. Mountainous terrains and isolated islands can be particularly challenging areas for mobile connectivity. Rail journeys, especially those that cut through rural stretches, might also experience less consistent coverage.

Before you fly

To ensure a smooth arrival, set up your eSIM before you land. Download maps for offline use if your plans include rural excursions. Once on the ground, you should find your service activates swiftly in urban centres, keeping you connected as you dive into the vibrant life of the UK.
