Instead of using a MySQL backend you can use a files backend:

[gammu]
port = /dev/ttyUSB0connection = at19200
# Debugging
#logformat = textall
synchronizetime = yes
# SMSD configuration, see gammu-smsdrc(5)
[smsd]
service = files
logfile = syslog
# Increase for debugging information
debuglevel = 0
# Paths where messages are stored
inboxpath = /var/spool/gammu/inbox/
outboxpath = /var/spool/gammu/outbox/
sentsmspath = /var/spool/gammu/sent/
errorsmspath = /var/spool/gammu/error/
