Adding a new member to a grandfathered plan

bourbon111111

    The three of us are currently grandfathered into an unlimited talk/text/2GB data plan, but a fourth wants to join our plan. Can she be added into the grandfathered plan, or would we all have to switch to TMobile One if she joins?

        This is a really good question and thanks for posting. It depends on how many plans your line can have. For example, if you've got a plan that allows up to 6 lines, and you're only using 4, then you'd be able to add an additional line with the same plan. Keep in mind, it wouldn't work the same way for grandfathered features, like data.
