Unlike T-Mobile‘s current Price Lock pledge which shields you from price hikes within the carrier’s control as long as you make no changes to your plan, the new version makes no mention of keeping existing prices. Instead, it will only bind T-Mobile to pay your final month’s bill in case a price hike makes you want to leave. You will have to notify the company within 60 days after a rate increase to make it pay your final month’s recurring service charges.
If you are not planning on removing or altering your current plan, T-Mobile will keep its previous Price Lock promise. The new guarantee will apply to those who add new lines on or after January 18 and those who make changes to their current plan or switch to an ineligible plan.
If you don’t like the new policy and see yourself opening a new account or adding new lines in the future, you might as well do it now before the current Price Lock pledge is phased out.
