Why buying a UK sim card?

Being connected to the internet makes life so much more easier, so imagine not having data on your phone when you travel to the UK! Think about ordering a cab on the streets or getting directions from Google Maps, finding a nearby restaurant with good reviews. So many simple things that you can only do when you have a working internet connection on your phone.

You can of course use data roaming or overseas data plans, but did you know that your internet speed will be limited. Plus, why pay $5 per day when for $30 you can get unlimited 4G/5G data for a whole month!? Data roaming is always more expensive than local prepaid sim cards.

Yes, these days all hotels, bars, restaurants, trains, busses, etc have free public WiFi. But did you know that this is an UNSECURED connection? Feels tricky right to check your cryptos on public WiFi! Just don't do it. The use of a VPN in these cases is recommended! Or what if the signal in your hotel room is too weak or the internet speed is nerve-racking? Just don't rely on others! Traveltomtom recommends you getting a local sim card when traveling.

Third and not unimportant, prepaid UK sim card deals are GREAT! Big data bundles are cheap in the UK, plus when traveling onwards in Europe, you can enjoy FREE EU DATA ROAMING on UK sim cards.

My recommendation

Traveltomtom recommends an EE prepaid sim card for traveling to the UK. They offer 30 GB data for £20 and the EE 4G/5G network is the best in the UK.

We always recommend local sim cards over international sim cards however, some international sim cards are great for when traveling to multiple countries. Check out my article a comparison of the best international sim cards for traveling in 2022 and find that travel sim card that suits your trip, e-sim cards are included in the article!

If you are NOT a fan of swapping sim cards and changing phone numbers then you might want to look into the option of getting a portable WiFi device for your trip to the UK. Personally I am not a fan and I will tell you why in my HONEST review about using a pocket WiFi when traveling.

But a portable WiFi device is so old school! The best way to get internet when traveling to the UK in 2022 is an e-sim card for the UK. Keep reading for the best e-sim cards for the UK!

E-sim card for the UK

I said it before but Traveltomtom 100% recommends e-sim cards for traveling. It is the most convenient and easiest way to stay connected when traveling. No need to go to a store any more, no need to swap physical sim cards, just an online process. You order an e-sim card, receive a code follow the instructions and you are able to connected to a foreign network when abroad and use the data allowance you purchased. Check out the following UK e-sim card deals:

  • 1 GB data for 7 days = $5 USD
  • 3 GB data for 30 days = $10 USD
  • 5 GB data for 30 days = $15 USD
  • 10 GB data for 30 days = $22.5 USD

For $49.90 USD you get 20 GB data + unlimited calls within Europe and 120 minutes worldwide. Click on the link to order directly or find more info.

Free EU roaming with UK sim cards

One of the best things the European Union came up with after the Euro was the ban on roaming costs within the EU countries. That means you can use the data on your UK sim card in more than 30 countries across Europe without paying anything extra. Calling minutes are also free within each country and back to the country where you purchased your sim card.

Brexit and free EU roaming

Brexit happened already in January 2020 which means the UK has officially left the European Union. But luckily the free EU roaming has not changed!  As of May 2022 there is still no news about EU roaming... which means good news: ROAMING IN EUROPE WITH A UK SIM CARD IS STILL FREE OF CHARGE AFTER BREXIT!

Mobile internet operators in the UK

Before I make a UK prepaid sim card comparison I will first show you all the available mobile internet operators in the UK. 

There are 5 main mobile internet providers in the UK:

  • Vodafone
  • O2
  • Three (3)
  • EE Mobile
  • Virgin Mobile

Virgin Mobile UK does not offer any prepaid or pay as you go sim cards for the UK!

On top of the above available mobile internet providers there are a dozen of other local sim cards available in smaller shops which I did not take into consideration, so called MVNO's. For tourists on a short stay I do not recommend any of these sim cards.

When arriving at London HeathrowLondon Gatwick, London Stansted or London Luton Airport you are able to buy a Lebara sim card or a Lycamobile sim card at the airport. Both sim cards also work fine for traveling in Europe. The problem is they have a lot of restrictions and surprises, like limited EU roaming, etc.

Note that calling bundles are for UK to UK calls, but also for local calls in other European countries. So once you travel to Germany you can call all over Germany as well as back to the UK, but NOT from Germany to Italy. This counts for all the prepaid sim card deals and packages with EE, Vodafone, O2 and Three.

Vodafone UK pay as you go sim card

vodafone uk sim card sim only prices 2021

Vodafone has 5 different UK prepaid sim cards available. If you don't use the main social media apps that consume a lot of data the smallest package is probably enough for your trip and you only pay £10 ($13.5 USD).

  • £10 = 5 GB data + Unlimited calling and texting
  • £15 = 10 GB data + Unlimited calling and texting
  • £20 = 20 GB data + Unlimited calling and texting

All the Vodafone sim only deals come with free EU data roaming and unlimited calls/text in the UK and Europe and all packages are valid for 1 month.

The Three UK prepaid sim card with unlimited data is an AMAZING option for travelers. Three UK Go Roam Around the World lets you use your sim card in 71 countries*: Australia, Brazil, United States, etc.

*Unfortunately data roaming packages are capped up to 20GB in Europe and 12GB in a go-roam destination outside of Europe like USA, Brazil, Australia.

NEWS! 3 UK just announced that there will be a GO ROAM UPDATE from 23 May 2022 and FREE roaming will from then on be chargeable! Go Roam within Europe will cost £2 per day and outside of Europe they will charge £5 per day for Go Roam. THIS IS VERY DISAPPOINTING Three UK!

EE UK pay as you go sim card

ee uk prepaid sim card deals

Last but not least EE UK. What I like about EE is that they have a wifi signal at every London Underground station. There is no phone signal in the London Underground so if you are about to buy a UK sim card and you know you gonna travel a lot in the tube this is something to keep in mind.

Another big plus is that EE has the best 5G network in the UK, so may be that could play a roll when looking for the best pay as you go UK tourist sim card as well. But let first see the sim only deals EE UK offers in 2022:

  • £10 = 5 GB data + unlimited calls + sms
  • £15 = 15 GB data + unlimited calls + sms
  • £20 = 30 GB data + unlimited calls + sms
  • £30 = 100 GB data + unlimited calls + sms

In the above we can clearly see that also EE offers competitive data packages. An EE prepaid sim card is free and for £20 GBP you get 30 GB data + unlimited calls/text in the UK AND in Europe. Data roaming is included and is NOT capped like with Three UK.

For the latest EE sim only deals have a look at their website in the link.

When doing my research for buying a sim card at London HeathrowLondon Gatwick, Luton and Stansted Airport I rated EE UK as the best buy!

GiffGaff UK sim card

Looking for another free sim card for the UK then have a look at GiffGaff. A Giffgaff prepaid sim card will be send to your home address for free before your trip to the UK. The activation is very quick and easy. GiffGaff operates on the O2 network in the UK.

Rates for GiffGaff UK sim cards are GOOD! All the pay-as-you-go data packages below INCLUDE unlimited calls/text within the UK.

For £35 GBP ($50) you get unlimited calls/text AND DATA in the UK.

Lebara UK sim card

lebara uk sim only deals 2021

Lebara UK also offers a free UK sim card and only charges for the data bundles. Their pay as you go bundles already start from £5 and gives you 2 GB data for 30 days. But there are more data bundles available.

For most tourists traveling to the UK the £15 sim only plan from Lebara is a good deal, but it give you much less value for money than Vodafone, EE, Three and O2.

What Lebara separates from the other Uk sim cards is that they offer free international calling minutes not only to the EU, but also to the USA, India, Thailand, Australia, Canada, China, Hong Kong, New Zealand, Malaysia, Israel, South Korea, Singapore.

Another great thing about a Lebara UK sim card is that you can also buy them in mobile phone shops and convenient stores across the UK like Tesco, Wh Smith, Argos, Sainsbury's. If you see shops with a Lebara sign you can get the same deals as online. Lebara operates on the Vodafone UK network and allows free roaming in Europe.

Best 4G/5G network in the UK in 2022

To make a fair UK prepaid sim card comparison we also have to look at the 4G/5G network coverage across the country. It would suck big time if you are on a UK road trip and as soon as you leave the city there is no service. Also who is happy with a 3G signal nowadays!? Exactly all we want is 5G! :)

Find below the UK 4G/5G network coverage maps per provider updated per February 2022.

Network coverage Three UK

Network coverage Vodafone UK

o2 uk 4g 5g network coverage

Network coverage EE Mobile UK

Three UK has an excellent network coverage and covers all the tourist destinations in the UK however, compared to the EE it has a weaker network strength. EE Mobile has the best 4G/5G network in the UK in 2022!

Best prepaid UK sim card for tourists in 2022

When I updated my comparison of the UK prepaid sim cards in May 2022 I came to the conclusion that prices these days are more or less the same. However, when we take £20 and see what we can get at the different providers we see that EE and O2 are offering 30 GB data and Vodafone only 20 GB data for the same price and that is not even 5G but 4G. Three offers only 12 GB for £22, so they are ranked at the most expensive UK prepaid sim card.

That said, Three offers the cheapest prepaid sim card with unlimited data in the UK: £28. At Vodafone you get 50 GB for £30 and EE and O2 give you 100 GB for £30.

As EE has the best 4G/5G network in the UK and also offers free WiFi hotspots at the London tube and gives you 100 GB without any data and speed limitations within the EU my conclusion is that EE is the best prepaid UK sim card in 2022!
