I am going to buy an iphone 4 from a friend and i plan on using it on tmobile.right now i have a samsung smartphone that uses a regular sim card.i was wondering can i buy a micro sim card from tmobile and transfer my current plan to that sim, or do i need to set up a whole new plan? if so would cutting my sim card just be helpful? or is there any other solution without touching my current plan?
