Hello I am thinking of purchasing an unlocked Lumia 900 and I have a few questions.
1. Can I swap the sim card from my iPhone 3gs into the Lumia 900 or do i have to get a new sim card?
2. Will this swap mess up my unlimited data plan?
3. Do I have to contact AT&T customer support to do this?
1. The Lumia 900 will need an LTE microSIM card.
2. No, you will be converted to an LTE unlimited data plan.
3. It's best to go to a corporate AT&T store to do this.
