UPDATE 17th sep 2019: PROJECT CLOSED, see post #147 .

Okay,

we´ve got many threads about "3g/4g" USB-sticks für Car Androids powerd by PX3/PX5.

BUT: most posts describe WiFi-Sticks and Sticks recognized as ethernet connection or ´WiFi-Hotspot Crap´ devices.....

i think we need a thread for

WORKING REAL MODEMS (detected as mobil-connection)

on this devices.....
