Making and receiving calls

Before you can make or receive any 
calls, you must turn on your phone 
and be within range of a network. 

5 Turning on your phone.

Networks
When you turn on the phone, it 
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.

Select the network to use, or you can 
add a network to your preferred 
networks. You can also change the 
order in which networks are selected 
during an automatic search.
