MR6450 crashes when SIM card is used

Hi,

I have an issue with my MR6450, it works fine when there is no sim card inserted but as soon as it boots with one in it crashes?

Firmware version: NTGX6_12_74.00

    I experienced the same issue.

     

    As a workaround, I downgraded the firmware and have been using an older version without any problems.

     

    You may want to try firmware version **12.01.31.00**. On my MR6150, that version works normally in **4G+5G mode** and does not cause the reboot loop.
