Tips for the UK
- The UK left the EU, so many EU-only regional plans exclude it. Check that 'United Kingdom' is listed before you buy.
- Access to three networks (EE, Three, O2) helps in rural Scotland and Wales, where one network can be patchy.
- London Underground has expanding 4G/5G coverage, but not every station or tunnel is covered yet.
