Nothing to do after hearing Apple tells me that the device is part of a replacement by defect campaign declared by Apple itself, but considering that 4 years have passed since activation, they warmly sent me to that country !! But I wonder if the defect is found by Apple itself because they put a time limit for solving the problem? Are they telling me that Apple has fallen into the same game as the competition? If so, they won't see me anymore ... ..

  • Hello, every now and then I get the problem no service (I have an iPhone 6 Plus 16 gb) the only valid way is to restore the network even 3 times if needed, so it magically resumes working.
    However before this I try with the activation of the airplane mod if it does not go through the restoration of the network, it always starts working again, however all this is due to the baseband because when it does not even go with * # 06 # to see imei is dead, it serves to secure network recovery.

  • What does the DNS of a Wifi network have to do with the problem related to the mobile network?
