Greetings
I changed the SIM and mounted a tested working one on a phone, my problem is that it does not receive IP from the cellular network, even if the signal is there. Latest firmware version available What can it be? Thank you

Check that you have correct APN and dial number settings.
Post what you have in System config > Status > System log.

Default dial number is *99***1# but it might be different, check with your operator.
Also post what you have in System config > Status > System log.

Dial number is set in System config > Network. But you don't need to specify it if the default one is used.
Is SMS script working for you?

If SMS script is working then the hardware is ok. This means that your configuration is wrong. Maybe a username or password is needed. Your operator should provide all settings - APN, user/password (if applicable) and dial-up number.

It's not a user script, it's an init sequence of the 3g/4g services. Usually this error means that the configuration is incorrect.
If you are sure that all settings are correct then the only option is to replace the SIM card.

Disable SMS script and 3g/4g connection then run this script once and post what you get in Logs. Don't forget to change apn variable value.

Keep the dial number default (dial = '*99***1#') and try again. This number is never your SIM number.

Connect script fails because of "NO CARRIER" message meaning that there's no mobile connection.
