I already have a phone plan with T-Mobile and was wondering if I can just get an EIP for a new phone.
I would then transfer my TMobile SIM on my existing phone over to the new one.
No you must have a plan
Everything goes through your account, and you don't need to add a line or such unless you are already doing an EIP and the amount they are willing to lend you.
