This widespread fast mobile internet reach makes getting online convenient for tourists across most of the country.

  • 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.

In addition to widespread coverage, mobile internet speeds across major networks in the UK are quite fast and rank among the fastest globally. However, keep in mind internet speeds will vary depending on the mobile operator, network generation (4G vs 5G), and location.

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.

Note: Kindly note that since Brexit, only Three prepaid SIM cards still provide limited free EU roaming.
