D-Link DWM-222 4G on Linux.

Will work on any new Linux distribution out of the box. No need to install the 'driver's.

In case yours is an old Linux distribution, just eject the detected corresponding cdrom device (/dev/sr0 or /dev/sr1, sr2 etc...) and a modem will be spawned which can be used just as a standard modem using your networkmanager or using wvdial.

In networkmanager or wvdial, just do not set the APN (or INIT3 string), the device will pick it up automatically. Older versions of networkmanager do not allow this, so you may face issues on it. In this caseu use wvdial with a high BAUD rate.
