I want to buy a new phone (first time). Also I want it to be a additional line meaning it will be add on a family plan.
First, should I buy a phone directly from a Tmobile store, Tmobile online, or other online store (ebay, etc.) ?
What do I need to do so it will be add on a family plan?
Will there be any complication on doing this?
I don't know much on this especially my mom.
Phones I am thinking about to buy:
Nokia 3660
Samsung E315
Samsung E715
Motorola V600
