Cellphone system structure
Every time you use your phone, there are several components involved for the phone to operate successfully
and to process a call:
All the features described in this user manual are supported by your phone. However, for all these features to work,
you must have a valid SIM card (supplied by your service provider) that also supports these features. If the network
that transmits your calls does not support a certain feature, the feature will not work even if you have a fully
featured SIM card. This last point is especially important when you are roaming networks.
