Operator claims fastest growing price plan ever

T-Mobile has signed the millionth customer to its Flext tariff just seven months after launch, claiming it to be the fastest growing price plan it has ever offered.

Unlike most other price plans in the mobile market, Flext offers an allowance measured in monetary value, not in minutes and numbers of text messages.

A customer can use this allowance on voice calling, text messaging, picture messaging or voicemail retrieval.

The success of the plan has put pressure on rivals to offer similar flexible plans. Vodafone launched Your Price Plan and Your Extras for its monthly contract customers in early September.

Vodafone claims that it now offers the most choice in the flexible plan market, as it includes music downloads and mobile television alongside voice minutes, text and MMS.
