Is SMS script working for you?

(23.05.2024, 08:31)admin Wrote: 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.

Now I have put new SIM tested on other LM and the new SIM working on ther LM.

(24.05.2024, 07:31)admin Wrote: 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.
