Thanks for your comments Matt.
I struggled a little bit to get the output from the AT commands, because the connection to ttyUSB2 through minicom seemed to be quite unstable (that is why i preferred qmi).
Anyway, I don’t think I am registered to the network… The output was as follows:

(nothing)In the network side there is the possibility to see UE’s potential activity, and the strange thing is that nothing happens…
Anyway thanks for your help.
