I have no any idea to fix that. What is the difference between MC7304 and MC7544 ?

For clarity I have uploaded a file of me doing the same operation at the link below and it works so I am not entirely sure what you are doing that could be different.
Thank you, this is working on my laptop too(Ubuntu 16.04, ModemManager off). I would like to limit the connection speed.
I would like to get ‘CONNECT 100000000’ intead of ‘CONNECT 150000000’ .
Is it possible?

The speed is not really 150000000, this is just convention to have a speed after the CONNECT message (some modems do not have a speed) with the high number indicating we are past the days of hayes modems at 9600bps. You are going to effectively be limited to the speed of the weakest part of the link between the host system and the end IP server be it the serial port, resources allocated from the LTE network, processing capability of the host system, back end IP, etc.
