So i lost my phone at a party. It had my sim card in it. The next few days, i called t-mobile to suspend my line until i get a new sim card. I ordered a new sim card from ebay and a used iphone 3G. If i call t-mobile and tell them i have a new sim card with a iphone. Will they help me activate it? or would they ignore me since i have a iphone. I need help.
