Networks

automatically selects your home network if
this is within range. If it is not within range,
you may use another network, provided your
network operator has an agreement that allows you
to do so. This is called roaming.
You can select the network you want to use, or
you can add a network to your list of preferred
networks. You can also change the order in which
networks are selected during an automatic search.
For all such options, scroll to Connectivity,
