MKR NB 1500 - no modem answer

I have seen the threads regarding that the modem is not working. But I cannot get mine to work...

Do you need an antenna and/or battery for the modem to start? I have only use the USB to power my MKR1500 without antenna.

And if anyone knows, can you connect to the network without external antenna?

Thank you in advance.

You definitely need an external antenna, as there is no antenna installed on the board and the modem will simply be destroyed without the use of an external antenna.

The fun fact is that I only know of the Arduino store, which with the MKR boards also "gives" an external antenna. Mouser, digi-key, german Reichelt etc. deliver without an external antenna.
