Unfortunately I haven’t been able to have a connection using the HAT.

I have bought 3 different sim cards and I haven’t had any success with them.

The only clue I’m following now is regarding this line…

+CSQ: 99,99^M

This actually means the signal is low. I bought antennas and haven’t received them. I’ll give it a try as soon as I get them.

Did someone experience this??

Thanks.

I was finally able to connect when I received the Antennas… :innocent:
