Chapter 4: Using the Commands

Setting Up the G24-L (Power On and Initial Actions)

There are three phases of connectivity for the G24-L:
•
Init General.
In this phase, the G24-L is asked to provide basic information which ensures that the phone
is functioning properly.
•
Enabling the SIM.
•
Registering the SIM on a network in order to see that wireless access is functioning properly.
After these three phases are completed, G24-L is ready for action and you can send/receive voice
calls, circuit switched data and GPRS.
