NAM update
The Number Assignment Module (NAM) in your phone
contains your assigned phone number(s) and other
system information that your service provider entered
during activation. The NAM update feature allows you to
easily activate or reactivate your phone without having
to go to your service provider. Updating the system
information in the NAM may improve your phone’s
coverage and performance.
Depending on your service provider, your phone is either
automatically updated or you can manually initiate an
update. During updating, the message
Updating service...
and the active call indicator may appear.
