X-3000 with the latest FW switch SIM card slots automatically

I have noticed that on reboot it will automatically switch the SIM card slots, therefore loosing network connectivity, because I have only one SIM, is there a solution for this? Thanks

Do you have this turned on? If yes, try turning it off.

That was the first thing I checked, It is not enabled, weird behavior

Do you mean that after reboot, it will switch to sim2 and not back to sim1?
