What would happen if I put another sim in my iphone?
I have an iPhone 5 for verizon which is unlocked for all other carriers. And it is a SIM card phone. I'm going to Mexico and I was wondering of I put a mexican SIM card in my phone will I lose all my info? Or what is the situation? Also I might switch to att and if I put an AT&T SIM card in my iphone will I lose all my contacts?
