Data roaming lets you use the internet and data services on your iPhone 5 when you are outside the UK.
Switching data roaming off on your iPhone 5 is easy and can be useful for peace of mind while you are abroad.
However, EE will not let you use data roaming without buying an add-on first.
How to turn data roaming on or off
1. From the Home screen, tap Settings
2. Tap General
3. Tap Mobile Data
4. Turn Data Roaming Off or On as required
