From 1st May T-mobile will introducing a simple flat rate call charge for pay monthly customers when calling numbers starting with 0870, 0871, 0872, 0843, 0844, 0845 and for calls to the Speaking Clock (123).
Calls to these numbers will be charged at 40p per minute.
Previously, call rates to these numbers varied between price plans and by 08 numbers.
However, their T&C read:
"5. Our Rights to Make Changes. Your Service is subject to our business policies, practices, and procedures, which we can change without notice. UNLESS EXPRESSLY PROHIBITED BY LAW, WE CAN CHANGE PRICES, CHARGES AND ANY TERMS IN THE AGREEMENT AT ANY TIME. IF WE MATERIALLY MODIFY THESE T&Cs IN A WAY THAT IS MATERIALLY ADVERSE TO YOU, OR IF A CHANGE INCREASES YOUR SET MONTHLY RECURRING CHARGE(S) (the set amount which does not include overage, features, optional services, taxes and fees you agreed to pay each month for at least a one-year Term), WE WILL PROVIDE YOU WITH AT LEAST 30 DAYS NOTICE AND YOU MAY TERMINATE YOUR SERVICE WITHOUT AN EARLY TERMINATION FEE (WHICH IS YOUR ONLY REMEDY) BY NOTIFYING US WITHIN 30 DAYS AFTER YOU RECEIVE THE NOTICE. IF YOU FAIL TO TERMINATE WITHIN THOSE 30 DAYS, YOU ACCEPT THE CHANGES."
This should be enough to cancel the contract early without paying a fee.
