10 GB Travel eSIM for the United Kingdom 🇬🇧

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.

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.

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.

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.

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.

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.

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!

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.

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

You can top up your United Kingdom eSIM using the WonderConnect app or through your web account.

Log in to your account, if you have several eSIMs, select the one you want to top up and choose a top-up package. Finalize payment and that's it.

Your top-up activates automatically when your current plan ends or when you run out of data. You can purchase it anytime - even before you need it. After your eSIM expires or runs out of data, you have 160 days to top up to regain the internet connection on the same eSIM.

The eSIM for United Kingdom works exclusively as a single-country plan. This means it only functions within the country's borders since it's designed to connect to local networks.
