Ive received 2 replacements from the Apple store. Model A1586 which is the sim free one. Both of them are doing this strange thing where it says searching even with no sim card in it. When I restore the phone it doesn't help. Anyone know what the problem is? Both my replacements from the Apple store do this. My sisters 6 which she received from Applecare does not. Both are the Sim free too. What is going on??
