Cross-Border roaming is a phenomenon that affects all providers and occurs when roaming close to a geographic border, where the cellular signal is stronger across the border than in your host country.

By default, your device will connect to the strongest available signal, which may originate from a country where usage charges are higher than your host country, unless you take steps to prevent it doing so. 

In the example of Cyprus (Europe Zone) and Turkey (Rest of World), voice, text and mobile data charges are set at the higher, non-EU rates in Turkey. When it comes to roaming data usage charges outside of the Europe zone, this is significantly higher than domestic and European charges. Please see our pricing guide for more information.

We are unable to control which network your equipment connects to. For this reason, we are not liable for any additional charges that are incurred.

To prevent connecting to a non-Europe Zone network from a Europe Zone country, go to your handset's setting options and manually select a network within your host country. This will ensure you remain connected to that network and only that network.

You should enable automatic network selection when returning to the UK.
