Getting Started
Subscriber Identity Module (SIM) card
You can change the subscriber identity module (SIM) card in your device.
As long as the new SIM card supports a data connection, the device
sends the telephone number associated with the SIM to the MCG 3100
during the log on process. You continue to make and receive calls without
changing your client configuration. People calling you do not dial different
telephone numbers when you change SIM cards.
Battery life
The battery life of your MCC 3100 device will vary, depending on the
amount of use. While operating in standby mode, you can expect
24 hours standby time while connected to a 2G network, and 10 hours
standby time while connected to a 3G network.
Standby mode is only available with Pocket PCs. Smartphones are either
on or off.
Standby mode saves power in the following ways:
• WiFi and Bluetooth connections are disabled.
• Device backlight, touchscreen, and audio are off.
• Programs are disabled and CPU activity is reduced.
You can receive cellular and Short Message Service (SMS) calls in
standby mode, and programs that are scheduled at a particular time will
reactivate the device.
The MCC 3100 for Windows Mobile configuration can impact the
operation of standby mode. For example, if you enable the Device
Standby option in the Advanced Settings menu, both the WiFi and cellular
radios will remain switched on when the device goes into standby mode.
There are many factors that affect battery life. If you have devices for
which you do not get the above standby time, then contact Nortel Support
to discuss the scenario.
