IoT Modules WCDMA Module

Hi sir/mam,
I am getting “Failed to register the network!” error as in the below attachment image. I am trying to use it with a Jio sim I have.
Can you please help me in this? And I would also like to know what does that error mean.
The Quectel Module that I’m using is UC20 Module.

Thank you!

Regards,
A Trilochan Kumar.

Hi @Thrillu ，
This issue is that your device cannot register with the network. Please check the status of the SIM card, antenna, and signal.
