Can I put two different phones (and SIMs) on the same prepaid TMobile account? Can you do this on any carriers?
On the same account, you should be able to. On the same line, however, you cannot. T-Mobile doesn't offer shared prepaid lines.
Verizon offers "share everything" plans, under which data, talk, and text are all shared among devices on said plan (in this scenario, one plan is applied to multiple lines within a single account). AT&T offers shared data plans (in which multiple lines under a single account share a data plan, but all have separate plans and usage quotas for talk and text). Neither Verizon nor AT&T offer these plans off-contract, however.
How would the same account work?
I want to have two phone numbers but share the $30/month plan.
Your account can have as many phones, each with their own number, as you want; but you have to pay a separate $30/month for each phone, you can't have multiple numbers sharing the one $30/month plan.
I've got two phones on TMO that were ported from AT&T about a week ago.. When I activated the 2nd phone I specifically asked if I could have the 2nd phone on the same account when talking to a TMO rep on the phone and was told 'no'. I've got an account and can login and it indicates "phones : 1" or something like that.. I'd like to see both phones so I don't have to keep two separate login's and pay twice instead of ponying up $60/mo for both $30 prepaid plans.. Anyone know if that is possible after the fact?
