Should you use automatic or manual network selection?

There are two ways of selecting a network. You can either set your handset to use AUTOMATIC Network selection or MANUAL selection. When using automatic selection the handset will look for all networks that it is able to attach to and logs onto the first network it finds. When using manual selection you must manually search through the networks and select a network to attach to. We recommend using automatic network selection. Please refer to your handset manual to check the default settings for your phone.
