Be sure gammu itself is reading from a right device path, and your user profile is in dialout group.
You may need to adjust bitrate to communicate to the module, so try to initiate direct communication using as example
screen /dev/ttyUSB0 115200
and see what value fits at best.The tool
gammu-detect
is also available, for spotting an initial configuration with a device, soman gammu-detect
for more info.
