Responding to early criticism of its One unlimited plan, T-Mobile on Monday announced some significant changes, including the creation of a "One Plus" tier costing an additional $25 per month.
The standard $70 One plan -- launching earlier, on Sept. 1 -- will now offer unlimited 3G tethering in the U.S., the carrier said. Previously that tethering would've defaulted to 2G speeds, forcing people to pay an extra $15 for 5 gigabytes of fast data.
The One Plus tier will upgrade subscribers to unlimited 4G tethering, unlimited HD video, and 3G international data roaming. T-Mobile had originally planned to make HD alone a $25 add-on, but faced significant blowback.
People on the regular One plan will still be limited to 480p video, but have the option of paying $3 for 24-hour installments of HD.
One subscribers will be able to add a second line for $50 per month, and $20 for each line after that in a family plan.
