Location: Hyderabad, India
Operating system name and version: Centos 6.8 x64
Version of smsd: 3.1.15
Smsd installed from: sources / package repository / from elsewhere... : Source
Name and model of a modem / phone: Huawei E1731
Interface: serial / USB / some adapter... USB


I have version 3.1.15 running fine. I tried to create prepaid balance and validity check through GSM1.cmdfile under /var/spool/sms/regular_run/ folder. I am able to get GSM1.statfile as following.

I am looking for a script which can decode PDU reply. Can you please help me with this solution ?

You can use a modem setting for automatic decoding:
ussd_convert = 2

Also here is a PDU Converter available in this forum, it has USSD Entry/Display field and defaults to GSM 7bit packet format.

And the smsd can be used for encoding and decoding ( smsd -D PDU... ), if necessary by some script, but in your case modem setting should be good.
