Hello there :)

I'm having a problem that I don't quite understand and it seems no one has had it so far or it wasn't documented ... at least I couldn't find anything.

What I'm trying to do, is sending SMS messages from my notebook (as soon as it works it'll be from a server) to my mobile. The above mentioned modem is connected via USB to my notebook and gets mapped to /dev/ttyUSB0.

With my current config the modem responds to the sms daemon and tries to send the message. To create the message I use the sendsms script that comes with the source.

Now the problem:
I get the error mentioned in the title. It seems to me, that I don't deliver the right IMSI Number to my provider. I've been calling my provider and asking for the IMSI number, though he won't give it out :/
Strange is, that the IMSI number shown in the log is the same as the serial number of the SIM card, can that be?

Recieving SMS works fine by the way... when I set the incoming option in the config to 1, I can send SMS from my mobile to the GSM modem.

Any help would be very apprechiated.

Thanks in Advance,

Below you'll find my current config, a complete log for sending 1 message and an failed sms file:
(Numbers [mobile,csms,imsi] have been changed)

The problem is solved. Another call with the provider made clear, that the number of the SMS center was wrong... I'm gonna try that now on the server, but I'm confident it'll work.

Thanks anyway :)

Just came to mind, you could remove the init = ATZ setting from the configuration. It causes that "echo" goes back on. Or if your modem really needs that ATZ, define it as a start string: start = ATZ.
