Once you arrive in a foreign country, your handset will automatically select a network (Automatic network selection) which allows you to use your handset without interruption because when you are in weak signal areas, your handset will automatically find a new network.

However, you can manually select a network to suit your usage. Manual network selection is so simple as below.

With manual network selection, you need to select a new network every time the signal breaks up.

However, if a text “emergency only” or “forbidden network” or “no access” appears on handset screen, you should select a network manually.
