Okay, a few things...

Are you using ModemManager? (My package is not compatible with it)

You also have my package misconfigured. Execute the command

uci set 3ginfo.@3ginfo[0].device="/dev/ttyUSB3"
uci commit 3ginfo

[kuyay]

Yes sir, i'm using modemmanager, thanks for your answers!

Can you give me some advice, what can I use to connect to my modem (beside ModemManager)?

[4IceG]

It would be best to uninstall MM (which takes control of the modem and makes it difficult for other packages to access the modem) and configure the connection using a different protocol, such as qmi.

[kuyay]

alright sir, thanks.
