List of Supported AT Commands
There are original files related to Cinterion GSM modules and Simcom UMTS modules
in the PDF format on the EasyGate CD-ROM.
Caution
n Since the GSM (UMTS) module is primarily used by the EasyGate central
processor for voice calls, use AT commands carefully. You might establish
wrong configuration of the module thus making EasyGate inoperative. To
solve most of these problems, switch EasyGate off and on again to make
the central processor execute full initialization of the module.
Do not use particularly:
