What could be the reason that the ubirch test kit is not connected to NB-IoT?
If you have acquired and setup the ubirch testkit hardware yourself, please make sure that you have flashed the NB-IoT firmware to the modem. See the testkit readme for a link to suitable instructions. Also, make sure that the antenna is connected to the correct port (next to the RGB LED). You can also try to move the testkit to an area with better reception.
