Shuts down, no signal and battery problems only with sim card inserted
I have 3 iPhones with the same symptom. Battery goes down quickly, shuts down or no signal ONLY when you insert de SIM card. I've tested all these 3 iPhones with no SIM card, and they don't shut down, no baterry drain. I've tested with several SIMs cards that work perfectly in other devices (I mean other iPhones)
Ist dies eine gute Frage?

I also concluded the same. In my case it seem batteries got faulty as I moved to 110V country from 220V and used a voltage transformer in front of adapter to charge the phone. It did something bad with the batteries. Though phone works fine when on charging. It shuts down only when I try to place a call. Thanks for this ans
