What to know about mobile data in the UK

The UK left the EU roaming regime, so 'Europe' on a plan does not automatically include it: each provider decides. On the network side, 3G is gone or going: Vodafone and EE finished their switch-off in early 2024, Three followed and O2 was completing its own at the start of 2026. Operators have told the government that 2G will go by 2033 at the latest. Signal is weakest in the Scottish Highlands, rural Wales and other upland areas.

Before you go

Before buying a Europe plan for a trip that includes London, check that the United Kingdom is named in the country list.
In Northern Ireland near the border, phones can pick up networks from the Republic of Ireland. Choose the network manually if your plan covers only one side.
For Highland walks or rural drives, save maps offline and tell someone your route. Coverage there depends on which UK network your eSIM uses.

Frequently asked questions

What is the cheapest eSIM for the UK?

On October 5, 2026, the cheapest plan we found was Yesim with 1 GB, 30 days at $3.00. The lowest price per gigabyte was aloSIM: 50 GB, 10 days at $25.00, which is $0.50/GB.

Is there an unlimited data eSIM for the UK?

Yes. 8 of the providers we track sell unlimited plans for the UK; the cheapest is Holafly at $3.90 for 1 day. Unlimited plans often slow down after a daily amount, so read the fair-use note on the provider page.

Which regional eSIM plans include the UK?

26 of the 69 regional and global products we track list the UK: Ubigi Europe, Nomad Europe (35 countries plan), Yesim Europe & UK, Holafly Europe, Saily Europe Unlimited (35 countries), Airalo EUconnect (European Union and United Kingdom), Saily Europe (34 countries), Airalo Eurolink.

Is the UK included in a Europe eSIM?

Sometimes. The EU's roam like at home rules stopped applying to the UK after it left the EU, so inclusion is a commercial choice by each provider. The country list on the plan is the only reliable answer.

Will my phone jump to an Irish network in Northern Ireland?

It can near the border. Ofcom and the Irish regulator ComReg have worked jointly on this inadvertent roaming problem. Manual network selection avoids it.
