   Legacy smartphone unlimited data plan: If you have a grandfathered smartphone data unlimited plan, you can keep the plan you have. This applies even if you upgrade to another smartphone or extend your contract. If you move to a new plan, you won’t be able to go back to your old unlimited plan. For new activations or smartphone upgrades, you have to choose from one of our current plans.
