Hello, there are gsm modems that send messages to users every time the equipment is rebooted, the name of the gsm modem in / dev changes, please tell me how to fix their names so that they do not change upon reboot?

I think it's worth looking into udev rules
. Here's an example of renaming a network interface:
vi /etc/udev/rules.d/70-persistent-net.rules

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="b8:ac:6f:65:31:e5", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="wan0"
