When I bought iPhone 5s two years back I gave away my unused iPhone 3 to my friend removing the sim which I inserted into my iPhone 5s . To my surprise though sim is removed, the contact numbers my friend storing in the old iPhone 3 which I gave him are also appearing in my iPhone 5s , causing confusion. Pl say why it's happening and how I can stop it.
Does it also happen my number also go into his phone
