This question is a bit outside of the scope of this project, as it is heavily dependent on your operating system (and, if on Windows, your modem's driver).

In Linux, most Huawei modems are accessible via multiple /dev/ttyUSBx entries - you can use e.g. /dev/ttyUSB2 for issueing AT commands (i.e. let python-gsmmodem use this) and another device (say, /dev/ttyUSB1) for internet.

Setting up the actual PPP (Internet) connection is currently outside the scope of python-gsmmodem; use NetworkManager, wvdial or whatever your distribution has to manage this.

The device node name/port number should not change between modem connections - my guess would be that the OS isn't releasing these nodes cleanly (again: this really depends on your OS environment) - googling would be your best bet, I'm afraid.
