What's Included in Every United Kingdom eSIM Data Plan

No matter which data plan size you choose, these details apply to all.
CoverageUnited Kingdom 🇬🇧

The eSIM works across borders in the countries listed below:

United Kingdom
Top up anytime

Need more data? Buy a top-up anytime. If your current data plan is still active, your top-up will be queued and automatically activated when your plan runs out or expires. If your plan has already expired or you’ve used up all your data, the top-up will activate immediately after purchase. No need to buy or install a new eSIM for the same destination—just top up and stay connected.

After your eSIM expires, you have 160 days to top it up.

Available top-ups:
1GB - valid for 7 days, $4.00
2GB - valid for 15 days, $5.50
3GB - valid for 30 days, $7.00
5GB - valid for 30 days, $10.00
10GB - valid for 30 days, $15.00

Network Providers

WonderConnect eSIM in the United Kingdom connects to O2, Three, and Vodafone - three of the UK’s leading mobile networks.

You’ll get strong 4G and 5G coverage across London, Manchester, Birmingham, Edinburgh, and other major cities.

The network performs well outside urban areas too. We tested it in remote spots like the Isle of Skye and experienced excellent internet speeds and stable coverage.

You’ll stay connected on trains, at airports, and throughout most of England, Scotland, and Wales. You might briefly lose signal in London Underground tunnels between stations, which is normal for all mobile networks.

Once you activate the eSIM, it automatically connects to the strongest available network in your location - keeping you online wherever your UK travels take you.

Your first UK eSIM? Here's What You Need to Know

Your Number Doesn't Change

WonderConnect eSIM for the UK provides mobile data without a British phone number. It means your home number stays the same, and if you want, you can still answer calls and receive SMS. This might be useful for authorization in banking apps. In your phone settings, you can decide whether to keep your home number active.
Doug W. - USA
"Traveled across the UK for a month with WonderConnect eSIM. My US number stayed active for calls while the eSIM handled all data. Worked perfectly in London, Edinburgh, and everywhere between. Finally, no more swapping SIM cards."

Activate When You Land

You can activate your eSIM as soon as you land. If you installed it before the trip, just go to settings, turn on the eSIM, and select it as your mobile data line. Final step - turn on data roaming for the UK eSIM. Usually it takes from a few seconds to maximum 10 minutes until your phone finds the network and you're online.
Bonnie T. - Australia
"Didn't expect it to work immediately. Activated the eSIM as soon as we landed in Manchester and had internet before leaving the airport. Perfect for tourists. Having navigation and access to all services from the start made getting around so much easier."

Apps Work as Usual

Once you're connected, all your apps work as usual. eSIM provides the internet for all your online activities. There are no limitations on what you can do with your data plan. To reduce data usage for the duration of your trip, you can disable app background refresh in your phone settings.

FAQ About United Kingdom eSIM

wonders

Does EU roaming work in UK?

No. After Brexit, the roam like at home rule doesn't apply to the United Kingdom. Data roaming rates depend on your carrier. There is no common European regulation that applies to the UK in terms of reduced roaming fees or free roaming. It means that if your carrier doesn't have any special offers, you will pay roaming charges for each gigabyte you use. That's why it's worth considering alternatives like an eSIM for the United Kingdom.

wonders

How to get eSIM for UK travel?

First, check compatibility. Your phone has to support eSIM technology. Next, select a data plan for your trip on this page or in the WonderConnect app. Complete purchase at checkout. You can select payment currency and preferred payment method. Once you finalize the payment, we'll send you an email with the QR code for eSIM installation. You can install the eSIM manually by scanning the code, or you can use the WonderConnect app for fast installation on iPhone.

wonders

Should I get an eSIM or physical SIM in the UK?

If your phone is compatible, select an eSIM. This way you can keep your regular card inside the phone - no risk to break or lose it. You can also get the eSIM in advance: select and install it at home before the trip. You'll skip looking for local stores, comparing carriers, and buying starter packs. With an eSIM you'll be connected faster, even before you leave the airport. It makes navigation convenient as you don't have to rely on free WiFi.

wonders

Can I use UK eSIM card in My US phone?

If your phone is eSIM-compatible and carrier-unlocked, you can use the eSIM for the United Kingdom on your US phone. Carrier locks are less common, however if you bought your device as part of a payment plan, you can double-check with your provider if they are blocking your device from connecting with other networks.

wonders

Can I buy an eSIM while I'm already in United Kingdom?

Yes! You can purchase your travel eSIM even after arriving at your destination. The only difference from buying it before your trip is that we'll guide you to activate it immediately, allowing you to connect to a local network right away.

With travel eSIM you decide when to buy it - either before the travels, on the go using WonderConnect app, or after you arrive at your destination.

wonders

When does my eSIM plan start?

Your eSIM plan starts when you first connect to mobile data at your destination.
You can install the eSIM anytime - even weeks before your trip. Installation does not start the validity period (unless you bought an eSIM for your home country; or a regional package that includes coverage for your home country. Example: Europe → Germany).

The countdown begins only when your eSIM connects to a mobile network at your destination. For this to happen, your eSIM must be turned on, selected as your mobile data line, and have data roaming enabled.

wonders

Can I use eSIM on my phone?

To use an eSIM, your device needs to be eSIM-compatible and carrier-unlocked. If you find your phone on our compatibility list, it most likely supports eSIM technology. In some cases, eSIM compatibility depends on where your phone model was manufactured. That's why we advise you to check our list before you buy one of our United Kingdom eSIM plans.

Carrier-unlocked means your home carrier (your mobile service provider) isn't restricting your phone from connecting to other networks. While carrier locks are becoming less common, if you're unsure, it's best to contact your provider. Just ask if they allow the use of digital SIM cards/eSIMs. If they do, you're free to avoid high roaming costs and enjoy affordable eSIM mobile data!

wonders

How do I set up eSIM for United Kingdom?

Setting up your eSIM requires 2 steps: installation and mobile data activation.

Step 1: Install your eSIM

Your eSIM for United Kingdom is ready to install immediately after purchase. You can install it anytime - even weeks before your trip. Installation does not start the validity period.

To install, choose one of these methods:
• Scan the QR code we sent you right after purchase
• Use the WonderConnect app with step-by-step installation guide and illustrations

Step 2: Activate mobile data (at your destination)

Once you arrive, complete these 4 steps:
1. In your phone settings, turn on your eSIM
2. Select the United Kingdom eSIM as your mobile data line
3. Enable data roaming for your eSIM (required to connect to foreign networks)
4. Turn off WiFi and test the connection by opening any website

Connection usually happens within seconds, but can take up to 10 minutes for your phone to catch the foreign network signal.
If you are using the WonderConnect app, activation instructions are accessible from the home screen.

wonders

Can I keep my SIM card and United Kingdom eSIM at the same time?

Yes! Most modern smartphones support dual SIM, which means you can use both your physical SIM card and the WonderConnect eSIM simultaneously.

You install the eSIM and it works alongside your regular SIM card. You don't have to remove it from your phone.

Set the eSIM as your mobile data line. For your regular SIM card, you have two options:

• Turn it off completely to avoid roaming charges for incoming calls
• Keep it on for receiving calls and text messages

Don't worry - turning off your SIM card doesn't delete your number or contacts. You can turn it back on anytime directly from your phone settings

wonders

How can I top up my eSIM?
