Your phone automatically checks for and connects to an available known network when a network connection is needed. Selection is based on the connection settings, unless there are application-specific settings applied.

Select > Settings and Connectivity > Settings.

Use a mobile data connection

Select Mobile data > On.

Use a mobile data connection when abroad

Select Allow mobile data usage > Worldwide.

Using a mobile data connection to connect to the internet when abroad can raise data transfer costs substantially.

You can also set the phone to use a mobile data connection only when in your home network or home country.

Use a WLAN connection only

Select Mobile data > Off.

An access point can be a mobile data connection or a WLAN connection.

You can collect access points in a destination list, and rearrange the priority order within the list.

Example:

If a WLAN access point is ranked above a mobile data access point in a destination list, the phone will always try to first connect to the WLAN access point, only connecting to the mobile data access point if the WLAN is not available.

Add a new access point to a destination list

Select Network destinations > Access point.

  1. Select Network destinations > Internet.

  2. Select and hold an access point, and from the pop-up menu, select Change priority.

  3. Tap the position in the list to move the access point to.
