How to configure sim on OpenWrt

I have a Quectel EC25 SIM module in my Phicomm K2P router. I have successfully installed OpenWRT on it. Now I want to use the Internet via SIM. I am using QMI protocol for that but there is an error coming which is network registration failed.

  • Did the modem work on the old firmware?
  • Are you sure your device does not have a carrier lock?
  • I did't tried the old firmware
  • no my device does not have any type of lock because my sim works in usb dongle

Do you have resolved your problem ? i'm with the same problem.
