T-Mobile started offering its new tier of data plans, with completely truly unlimited data, today. The previous unlimited plans were capped and throttled at 2GB. To sweeten the deal T-Mobile is offering it's second top seller for free while an online retailer is offering free activation and discounts.
The first announcement was unclear and we contacted T-Mobile to find out how the upgrade process works. Say for example you already hide a 2 GB unlimited data plan and you wanted to upgrade to the truly unlimited data plan here's the official statement:
“New and existing T-Mobile customers will be eligible for T-Mobile’s new Unlimited Nationwide 4G data plan. Existing Value and Classic plan customers can simply migrate to the new Unlimited Nationwide 4G data plan without extending their two year contract. T-Mobile customers on grandfathered plans who choose to migrate to the new Unlimited Nationwide 4G data plan will be required to sign a new two-year contract,” said McLaughlin."
