What's the best option for staying connected in the UK?

If you are planning to visit the UK, whether you are going on a business trip or just for pleasure, you will need internet and telephone access. Since the country is no longer part of the European Union, using your local SIM card could incur an expensive bill and roaming charges (although many providers have no roaming charge agreements). valid roaming with the UK - see below).

To avoid this, we suggest getting a prepaid data plan. Here you have two options. You can either buy a prepaid SIM card or get an eSIM. If you don't have a next-gen phone, you'll have to stick with traditional SIM cards. But if your device is eSIM compatible, this is a much more convenient option. Here's why.

European Union travellers: Your current mobile subscription may still offer "free roaming" across the UK. Brexit is quite recent and most telecom operators have decided to keep the free roaming agreement which is still valid in the EU despite Brexit. you might want to check that out!

The best prepaid eSIM plans for the UK.

eSIMs are digital SIM cards and therefore very convenient. eSIMs are "embedded SIMs" or simply a new version of SIM card technology. It uses a reprogrammable chip that sits inside your device. Typically, to install an eSIM, you need to scan a QR code with your smartphone or install your eSIM through the provider's mobile app if they allow it. The biggest advantage of an eSIM is that it is much faster and easier to switch between different mobile networks. Here are the best prepaid eSIM options for the UK.

Mobile subscriptions: do local operators offer eSIM (O2, EE, Vodafone)?

If you're staying long-term (at least several months) in the UK, your best option might be to get an eSIM subscription and sign up directly with one of the local telecom providers. This will probably be the better option price-wise and more affordable than getting a prepaid eSIM.

If you want to get an eSIM on UK mobile networks, you have three options. On EE, you can get one on Pay Monthly, Small Business, and SIM Only plans. But to use one, you will first need a regular SIM card. Then you can order an eSIM and replace your traditional SIM.

On O2, however, you can change your Pay Monthly contract to an eSIM. Three – another UK mobile network – is set to launch its eSIM this year. Vodafone offers perhaps the easiest option. You can simply order an eSIM online and start using it immediately.

Without EE, O2 and Vodafone, it is also possible to buy an eSIM from roaming providers. On you will find many different plans. You can choose one, according to your needs and desires. Most eSIMs work with the O2 network and Vodafone.

Is there 5G in the UK?

Although 5G was officially introduced in the UK at the end of May 2019, it still only works in certain areas. Currently it is offered by all four major networks - EE, Vodafone, Three and O2. Now it is available in 55 locations including London, Glasgow, Manchester, Birmingham, Bristol, Lancaster, Cardiff, Gatwick, Liverpool, Plymouth, Stoke-on-Trent and Wolverhampton.


eSIM is definitely a great option for getting mobile data if you're traveling to the UK. We hope the few options we've suggested will meet your data needs. Otherwise visit and choose from many other options available for the UK.
