I currently have a T-Mobile phone on the $15 monthly plan. I am interested in replacing it with a used smartphone and getting the $30/mo 100 minutes talk/5GB data plan and have some questions about the procedure for switching.
- What do I need to qualify for the $30 plan and how do I activate it? Am I forced to buy a new sim card, or can I just use my current one (assuming it fits my new phone)?
- Can I use a phone that is not unlocked, but originated on the T-Mobile network?
- What are the overage charges for minutes on the $30 plan?
- Can I use my existing prepaid balance and number?
