Home Page Forums Raspberry Pi Shields 3G/LTE Connection Issue Reply To: 3G/LTE Connection Issue



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

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.

Let’s stay in touch… @pedrodiazsos on twitter.
