Most mobile phones support 2G, 3G and 4G networks, but some older phones only support 2G.
A number of operators in other countries no longer offer a 2G network. You may therefore no longer be able to establish a network connection with these operators from your old mobile phone. What about your particular mobile phone? Use our handy tool to check (under Specifications > Networks).
Still want to make a connection? Set your mobile phone to manually search for another network in the country you are visiting. It will scan all the available networks and provide a list that shows whether each network supports 2G, 3G or 4G. Then you can select a different network.
Note: Sometimes you have to try manually several times before you get a connection.
Good to know: You can also switch to Wi-Fi, if your handset has this capability.
