IoT connectivity in United Kingdom

The UK has four national operators (EE, Vodafone UK, O2, Three) with strong urban coverage and variable rural reach. 3G shutdown executed in 2024 by most operators. 2G expected until 2033. NB-IoT and LTE-M available on EE and Vodafone. Post-Brexit, IoT SIMs retain permanent roaming with no significant technical restrictions.

Caveats and regulatory considerations

  • 2G runs until 2033, but new deployments should target LTE-M
  • No specific regulatory restrictions on permanent IoT roaming
