Sim2 goes undetected after sometime.

I tried both in safe mode and normal. The Sim2 is alive, say for  2 minutes and then disconnects, as if no Sim has been Inserted. It also kicks me out to locked screen when this swift happens. Please help.

Try changing SIM cards in places, maybe there is a problem in the map. Sony does not welcome the compatibility of the card and two sim cards, after a reboot, problems begin.

Now both the SIMs are alive.
