When visiting the UK, travelers have several options to get online, each with their own pros and cons. In this blog post, we’ll explore the mobile internet in the UK and provide tips on choosing the best connectivity option for your needs and budget.

The Mobile Internet in the UK

I. Mobile Internet Coverage and Speed in the UK

Mobile internet in the UK is readily available and reliable, particularly in major cities and popular tourist destinations, though coverage can be patchy in rural regions. Below are coverage maps for some of the main network providers so you can check signal strength throughout Britain.

1. The UK Mobile Internet Coverage

The UK benefits from extensive 4G LTE coverage from all the major mobile operators, with over 99% of the population covered. 5G networks are rapidly rolling out as well, available in many major cities and towns from all providers.

Some key facts about mobile internet in the UK:

  • Three – Across the UK, Three has the most extensive 4G coverage at around 99% of the population. It also has the widest 5G network currently reaching more than 99% of the population.
  • Vodafone – Vodafone has been rapidly expanding its 5G network and now reaches over 97% of the population. Reception in rural parts of Wales, Scotland and Northern England can be intermittent.
  • O2– Its 5G network is growing steadily and now covers a majority of large towns and cities. O2 coverage is slightly less consistent in very remote rural locations.
  • EE– EE has extensive 4G networks across all of the UK’s major cities and population centers. Around 98-99% of the UK is covered by Three’s 4G. Its 5G rollout is progressing well in urban areas. Coverage in sparse rural parts may not be comprehensive.

Overall, travelers in most populated areas of the UK should have a strong 4G signal as well as growing 5G availability when using a local SIM card or eSIM during their stay. Just be prepared for occasional drops in service when in remote areas or underground transit.

2. The UK Mobile Internet Speed

National Ranking:

  • Overall: United Kingdom currently ranks 49th in the world for download speed, with a median of 50.96 Mbps. The UK’s mobile networks deliver internet connectivity that is reliably fast enough to stream HD video, use data-heavy apps, video chat and more without issue. Speeds continue to climb annually as networks invest in infrastructure upgrades.
  • The UK is among the global leaders for average mobile internet speeds compared to neighboring European countries. Continued investment is ensuring Britons enjoy high-performance connectivity on the go.

City Ranking: 

  • London – Average speeds around 100-150 Mbps across all networks. Wide 5G coverage boosts speeds even higher in Central London.
  • Edinburgh – Consistently fast speeds of 70-100 Mbps on average thanks to strong 4G from all carriers. 5G accelerates speeds further.
  • Birmingham – 4G speeds average 60-80 Mbps. Growing 5G infrastructure enhances speeds over both EE and Vodafone 5G networks.

To enjoy the fastest mobile data speeds look for a 5G compatible device and SIM card or eSIM on a network like Three with broad coverage. But even 4G speeds should be sufficient for typical tourist usage like maps, social media, messaging, web browsing and more.
