I bought this modem model. The main reason is to ability to send sms from debian 11 server machine console or script
First of all I tried to check if sms sending is working under windows I tried to use manual sms send But not successfull I'm not expert in gsm networks I tried some commands to understand if modem registered in gsm network All commands history you can see on screenshot I got error My Operator is Latvia Tele2 PIN code asking is removed from sim card
On debian 11 machine modem is detected but minicom cant connect to modem I tried all ttyUSB ports but minicom show offline status It will be next question For linux is smsutils package which allow to send sms via gsm modems connected to usb port
Can somne one assist how to check if modem registered in gsm network and why ot cant send sms?
