Respected sir,
This is to inform you that my name is Nandlal Chaurasia and i'm a apple iphone 5s user.i'm facing many difficulties about this product.the when ever some calls me 1st call auto disconnecting after 1 ring. I thought its SIM issue bur same SIM is working fine in other device and other SIM is having the same issue with my phone.
I had submitted my iphone more than 3 times but the problem is still not solved.this service is poor and the .i had contacted many time to the service center but they are not able to fix my iphone.
I had never expected...
