Check permissions of /dev/ttyUSB*
pi@raspberrypi:~ $ ls -l /dev/ttyUSB*
crw-rw---- 1 root dialout 188, 0 Jan 15 12:59 /dev/ttyUSB0

crw-rw---- 1 root dialout 188, 2 Jan 15 12:57 /dev/ttyUSB2
based on above details, the user using gammu have to be member of dialout group.

Luckily I am member of dialout group.
