EU and international roaming for Three, O2, EE, Tesco, and Vodafone — post-Brexit rules clearly explained.
Since leaving the EU, UK networks lost the obligation to offer EU roaming at domestic rates. Most reintroduced charges — but O2 kept EU roaming free on all standard plans, making it the only major UK MNO to do so as of 2026.
O2 is the only major UK MNO not to reintroduce any EU roaming charge. Every O2 Pay Monthly plan includes free roaming in 49 European destinations with a 25GB/month data fair-use cap. O2 Plus Plan customers get the Travel Inclusive Zone — 75 countries including USA, Canada, Mexico, Australia, New Zealand. O2 won Uswitch Best Network for Roaming 2025.
Three's Go Roam is the UK's most extensive roaming programme by destination count. Complete plans: 163 countries at no daily charge — Europe (49), Around the World (USA, Australia, Brazil + 19 more), Around the World Extra (India, Japan, UAE, Canada + 89 more). Fair use: 12GB data, 3,000 minutes, 5,000 texts/month. From April 2026: non-Go-Roam rates £2.75/day EU, £8/day worldwide.
EE Essentials: £2.29/day in 47 European destinations. All Rounder+: free EU with monthly data cap. Full Works: Roam Further Pass — free roaming in Australia, Canada, Mexico, New Zealand, and USA too. Annual price rises: SIM Only voice +£2.50/month each March.
Tesco Mobile covers 48 EU and international destinations at no extra charge — all EU countries plus Iceland, Norway, Switzerland, Channel Islands, Isle of Man, Gibraltar. Tesco committed to 30 days' notice before any fee reintroduction. 62-days-in-4-months fair use limit applies.
Under Ofcom's January 2025 rule, all networks must state the exact £/p rise at sign-up. You have a 30-day penalty-free exit window if a rise was not properly disclosed. Tesco Mobile Clubcard Price plans have frozen prices — no annual rise.
