How to read incoming sms message python via modem?

Question

Python

I have a Huawei e1550 modem with sim card and rasberrypi. I need to make sure that if a message arrives on the SIM card, then the function is executed. I tried to do it through the gsmmodem library, but it throws an error TypeError: a bytes-like object is required, not 'str' and it does not fix in any way. and it's not about my code, since I took the code from the library's github. I also tried using pyserial, but it only displays the number from which the SMS came. Please help, I haven't been able to find a solution to this problem for a week now.

Answer 1

TypeError: a bytes-like object is required, not 'str'

Well, process it as a string already.
How many bytes are left?
I'm probably the only one here who fumbles with TPU and controllers.
