Hi. Yesterday I have purchased Moto X Style. My sim card was a micro and it must be converted to nano. I have gave my number and friend cut it with a special tool which has been created for this purpose. I have put it inside the sim card slot and it worked normally. But, after 15 minutes it has stopped working unexpectedly. It shows that "No Sim Card". I have tried to put card out and in again and again... But nothing helps
