Network notes

EE (BT-owned) has the broadest 5G coverage and rural reach. Vodafone and Three are competitive in cities. O2 lags slightly outside urban areas. Most travel eSIMs resell one of these and you’ll rarely notice the difference in London, Manchester or Edinburgh.

Practical connectivity tips

• Tube and Underground: 4G/5G coverage is now live across most of the London Underground network on EE, with Vodafone, O2 and Three rolling out — but availability depends on which carrier your eSIM resells. Don’t rely on it for navigation.
• Contactless on transport: Use Apple/Google Pay on TfL — no need to buy an Oyster card. Your eSIM doesn’t need to be the same line.
• Apps you’ll want online: Citymapper, National Rail, Uber/Bolt, OS Maps for hiking, TfL Go for London.
• Rural Scotland and Wales: signal drops to 3G or none in glens and national parks. Download offline maps.

Watch out for

• EU “Eurolink”-style regional plans don’t always include the UK. Check the destination list before buying. Some include UK; some don’t.
• Switzerland and Norway likewise: not EU, often excluded from Europe plans even though they’re geographically central.
• UK number-based 2FA from foreign banks sometimes fails — apps with authenticator codes are more reliable.
