+Boy ka Sorry, these are the same videos. The first one is connected to wifi, look at the symbol. The other videos are Android 4.4.4, not 5.1. This is what I got via Email: "The 3G network connection does not work on this latest android 5.1 version, it is the unit's defect, we are updating the system, once updated will send you new firmware."

Herr Oekonomierat I think it can compatible and work on android 5.1 version, but some dongle doesn't can work.
