Try with init = AT+CPMS="SM". If it does not help, use a modem setting report_device_details = yes and show those details here.

Still not working, thanks for the quick reply.

Are sure that there should be a message received in the modem?

As your modem is Huawei, you could use the following settings:



Please check what ports are provided by the modem ( ls -l /dev/serial/by-id/ ). If there are three ports, try to use the last one, for example device = /dev/ttyUSB2. Try to send a message to SIM's own number.

/etc/smsd.conf

Still not working, i'm getting this... I'm sensing that this modem is "programmed" wrong.

Was there /dev/ttyUSB2 and did you try it?

As the modem did not accept AT^CURC=0, perhaps the firmware is bad. You need to comment out init2 setting.

Have you tried to send SMS? If not, you should try to send SMS to it's own number, to see how sending works.

Yes, i tried all ports..

I also tried this, but with no success

Sending SMSs works fine, i also tried sending an SMS to it's own number but with no success on receiving it.

I will buy another modem. Thank you so much for your answers.

I bought a new 100% original Huawei E1750 and it worked. Lesson learned again.

Thank you @keke for your answers!
