Phone overheating with SIM card

[MayB4ck]

mym s4 mini i9195 overheats when sim card inserted, doesnt matter if screen is on/off, tried cm 13,cm 12,stock rom but still same result... What can be the problem? I don't have any other phone to use right now so this is my only hope

Changing the modem doesn't seem to fix this problem, Putting it into airplane mode cools it off quickly, wifi and cellular radio drain the battery the most, please help me, i really need the phone
