When you arrive in a country, we’ll automatically connect you to the best available network. If this doesn’t happen, go to your phone’s settings and choose mobile network settings to manually search for and connect to a provider of your choice.
In countries where 4G is available you can use 4G at no additional cost to your standard roaming charges, providing you have a 4G device and bundle in the UK. If 4G isn’t available in your destination, you’ll be connected to 3G or 2G.
If you need to, you can change the automatically-chosen network in your phone’s network settings. This doesn’t affect price; you pay the same whichever network you connect to.
