Yahoooooo…

Received the new MiFI today, and installed the “old” radio on it.
Update the MiFi with: openwrt-mifi-20160120.bin, added the needed data for my 3G provider and set it to use COM3

Guess what…

And yes.... Internet is also working over 3G :-)

I guess that the 1st MiFi I received did have a problem with the SIM card reader.
