sorry,english isnt our mother language here.. and im also bad with it lol. So it doesn't affect the iPhone at all? It will not ask me to use the original sim I had first put and everything? thanks! great help🙂 The micro sim here is less than a dollar so I might as well buy those instead of putting so much effort in cutting a sim card. the only thing i needed to know is, if it will affect my phone if I swap sims even though it unlocked😛
