had iphone a while now, and to be honest cant really remember how I transferred my contacts from my sim. But its really starting to annoy me . First of all even though theyre in your contacts , their texts come up as unknown numbers? Furthermore when you "add to contact" the problem still persists. Its quite a nuisance because you'll get a text and not have a clue who it is! whats the best way to transfer contacts from sim? and please don't suggest the manual option.
