Hello JH

If SerialOptions defaults (parity, csize, flow, stop) are good for you

SerialOptions() : device(), baudrate(9600), timeout(seconds(0)),
            parity(noparity), csize(8), flow(noflow), stop(one) {}

then try to add \r to the end of your AT command
- serial<<"AT+CGDCONT?" << endl;.
+ serial<<"AT+CGDCONT?\r\n";

AFAIR, AT commands, use it as line end (ref
https://en.wikipedia.org/wiki/Hayes_command_set), but on Linux
std::endl only LF(0x0A).
Maybe this is your case.
HTH.
