While I don't have this breakout board, I have used that module before and I know it relies on MUX to handle multiple devices on one port. You might want to check if +CMUX has been enabled. That would cause whatever port it is enabled on to be unreadable by simply connecting to it with a terminal program. You would need to use the telit serial port multiplexer software to read/write from it properly, or simply disable it.
