Good day,

May i know what is the firmware on the device ?

Did you tried the latest firmware ?

I can see that you are able to ping

Is the issue only with sms receiving and sending ? or there is not internet connectivity as well ?

If network state is timeout there should be no connectivity.

Are you using both the mobile antennas?

Can you share ss for the mobile information ?

What is the APN ? Is auto ? Have you tried keeping it on manual ? ( You can simply uncheck auto then the custom APN will itself appear in the field and you can simply save )

Have try to set the APN manually. But it happen again.

May i know what is ss for the mobile information?

It is recommended to use both the mobile antennas . 

Further could you check in the storage if the storage memory or sim memory is not full.

Also have you tried inserting the sim card in the mobile or other device ? Just to check if sim card is working fine in sending and receiving the sms.

Mobile information meaning Status>Network>Mobile . 

After trying all above please try to re-flash firmware in boot loader mode .

Steps for updating firmware in bootloader menu could be seen here:

I hope it helps

If you need more help please feel free to contact back.

Thanks .

Have  a nice day.
