Hi there, My old phone fell out of my pocket and shattered on Wednesday, the screen no longer works and i am going to replace it. My old phone was the Samsung Galaxy Ace 2 x which has a normal sim card. The phone i would like to replace it with is the samsung galaxy s4 mini which has a micro sim card. My question is, if i bring an unlocked samsung galaxy s4 mini, can i buy a micro sim and transfer my number and plan from my old sim to the new one? Thanks!!
