Selecting a Mode

When you select a preferred mode, your phone 
looks for that type of service first. If it cannot find 
your preferred service, after about five minutes, it 
switches automatically to your non-preferred 
service. If the phone switches to a non-preferred 
service, it checks at regular intervals (every 30 
minutes) to see if your preferred service has 
become available. The exact intervals that your 
phone switches modes and checks for preferred 
service varies depending on your SIM card. Check 
with your service provider.

The phone postpones a switch 

between modes while you are in a call or are 
actively using one of the phone’s features.

If you select an always mode, your phone always 
accesses that type of service. If you become out-of-
range in that mode, the phone does not switch to 
the other type of service. You have to manually 
switch it to the other mode by changing the settings 
in this menu.
