I try to connect internet via AT commands with FIBOCOM modem. Sequence as follows. I got different techniques about it AT+COPS for example for carriers. But I guess I cannot go any further.
_serialPort.Write("AT\r"); Thread.Sleep(2000); _serialPort.Write("ATZ\r"); Thread.Sleep(2000); _serialPort.Write("ATE0+CMEE=1;+CREG=2\r"); Thread.Sleep(2000); _serialPort.Write("AT+CPIN?\r"); Thread.Sleep(2000); _serialPort.Write("AT+CSQ\r"); Thread.Sleep(2000); _serialPort.Write("AT+CREG?\r"); Thread.Sleep(2000); _serialPort.Write("AT+CSQ\r"); Thread.Sleep(2000); _serialPort.Write("AT+CMGF=0\r"); Thread.Sleep(2000); _serialPort.Write("AT+CIMI\r"); Thread.Sleep(2000); _serialPort.Write("AT+CGSN\r"); Thread.Sleep(2000); _serialPort.Write("AT+CPMS?\r"); Thread.Sleep(2000); _serialPort.Write("AT+CGDCONT=1,\"IP\",\"infoteks\",\"0.0.0.0\",0,0\r"); Thread.Sleep(2000); _serialPort.Write("AT+CGQMIN=1,1,0,0,4,31\r"); Thread.Sleep(2000); _serialPort.Write("ATD*99***1#\r"); Thread.Sleep(2000); After this sequence done I got these report

COMMAND IS AT+MIPCALL=1,"APN"/r
apn is acess point name if you give right name it will return ok and after some time 20 sec max it will return connected ip address
