Debian Squeeze / oldstable:
smstools 3.1.14-1.2:
Smsd installed from: from Debian Wheezy package repository
Name and model of a modem / phone: Cinterion MC55i
Interface: /dev/ttyS0

After replacing SIM with one from a different mobile network we get "CMS ERROR: 29"

Is there any information I can get on how to troubleshoot this ? Thanks
