3.3.2 UMTS SETTINGS

When the Active Carrier supports UMTS, the fields on this page will be enabled. A specific Band of operation can be chosen

and various SIM settings can be changed.

One of the key features of GSM (UMTS) is the Subscriber Identity Module (SIM), commonly known as a SIM card. The SIM is

a detachable smart card containing the user's subscription information. This allows the user to retain his or her information

after switching handsets. The SIM has a security feature which, when enabled, will require the user to enter a valid PIN

before the modem will connect to the cellular network.
