Currently, I am working on Telit UL865-EUD 3G Modem. I worked with Telit GL865 GPRS modem before that's why I am familiar with AT commands and initialization logic.
My problem is that my UL865 modem always returns "NO CARRIER" to ATD*99***1# command. It is not only specific to ATD*99***1#. It results also same with other ATD Commands.
UL865 module is working. I attached to the network and open TCP socket. I tested them. But Dial Commands are not working.
Firmware Version : 12.00.616
Is there anybody who faces the same problem before?
