Mobile Roaming: Use Your Phone Abroad
Everything you need to know about using your UK mobile phone abroad. Post-Brexit EU roaming charges, network policies, and money-saving tips.
Post-Brexit EU Roaming
Based on reader feedback and our own testing, here's what you need to know about using your phone abroad.
Since Brexit, UK networks are no longer required to offer free EU roaming. However, most networks still offer inclusive roaming with limits. Here's what you need to know:
- Most networks include EU roaming but with data caps (typically 5-25GB)
- Exceeding your roaming allowance incurs charges (usually £2-3/GB)
- Calls and texts to UK numbers are usually included
- Some plans charge daily fees for roaming (especially newer plans)
- Always check your specific plan terms before travelling
Important: Roaming policies change frequently. Always check your network's current roaming policy before travelling. The information below is general guidance for 2026.

Tips for Using Your Phone Abroad
Before You Travel
- Check your plan's roaming terms
- Download offline maps and content
- Note important numbers (save locally)
- Set up a spending cap if available
- Consider a local SIM for long trips
While Abroad
- Use Wi-Fi wherever possible
- Turn off automatic app updates
- Disable background app refresh
- Use messaging apps over Wi-Fi
- Monitor your data usage in the app
Avoid Bill Shock
- Turn off data roaming if you don't need it - use Wi-Fi only
- Beware of cruise ships and ferries - they often use expensive satellite networks
- Check border areas - your phone may connect to networks in neighbouring countries
- Avoid calling premium numbers - these aren't covered by roaming allowances
- Set up usage alerts - most networks can text you when you reach 80% and 100% of allowance
Alternatives to Network Roaming
Local SIM Cards
For longer trips, buying a local SIM card can be much cheaper than roaming. You'll get a local number and local rates. Your UK phone must be unlocked to use a foreign SIM. Ask your network to unlock it before you travel (usually free after your contract ends).
Travel eSIMs
If your phone supports eSIM, you can purchase a travel eSIM online before you leave. Services like Airalo, Holafly, and others offer data packages for most countries. Your UK number stays active for calls and texts while data uses the eSIM.
Portable Wi-Fi Devices
Rent or buy a portable Wi-Fi hotspot for your destination. Multiple devices can connect, making it cost-effective for families or groups. Companies like Skyroam and TEP Wireless offer worldwide coverage.
