Does EU Roaming Still Work in London?

Yes. Many EU SIM cards still work in London through roaming agreements between European and UK mobile operators.

However, roaming conditions now vary depending on the carrier because the UK is no longer covered by EU roaming regulations after Brexit.

Why Roaming Rules Changed After Brexit

Before Brexit, the United Kingdom participated in the EU “Roam Like at Home” system.

This allowed EU travelers to use mobile data, calls, and SMS in London and the rest of the UK without extra roaming charges.

After Brexit, mobile carriers became free to create their own UK roaming policies.

Some operators continued offering free UK roaming, while others introduced:

  • Daily roaming charges
  • Fair usage limits

  • Travel packages
  • Speed limitations

Do All EU Carriers Include London Roaming?

No. Roaming policies vary between operators.

Some European carriers still include London and UK roaming in standard EU plans, while others charge additional fees.

Travelers should always check:

  • Roaming costs
  • Daily fees
  • Data limits
  • Speed restrictions
  • Fair usage conditions

Why Many Travelers Use UK eSIMs Instead

  • Predictable prepaid pricing
  • No unexpected roaming fees
  • Reliable 4G and 5G coverage
  • Instant activation
  • Flexible mobile data plans
