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.
