T-Mobile launches ‘Flexible Booster’ mobile deals

New 18 and 24 month plans replace Combi and Flext


The variety of mobile phones on offer in shops can seem bewilderingly large

T-Mobile has today introduced its new range of ‘Flexible Booster’ based mobile tariffs that replace its previous range of tariffs including Flext, Combi and Solo.

The introduction of ‘Flexible Boosters’ are part of a total revamp of T-Mobile’s pay monthly portfolio. T-mobile claims its new range of plans offer mobile customers ‘an easy way to create the perfect personalised mobile package by making simple choices based on the things that are most important to them’.

T-Mobile’s tariff changes come in the wake of its planned merger with rival mobile operator Orange. The proposed Orange T-Mobile merger will shortly be subject to scrutiny by either the European Commission or the Office of Fair Trading.

New T-Mobile tariffs

The cheapest new T-Mobile pay-monthly plan costs £10 a month on a 24 month contract. The deal includes 100 minutes and 100 texts plus one ‘Flexible Booster’. On this tariff there’s a choice of four free mobile phone handsets, including the Nokia 6303. 

If you’re willing to pay a bit more, for £20 a month you can get a free Blackberry Curve 8520 smartphone on an 18 month deal, which includes 300 minutes, 300 texts and a T-Mobile Flexible Booster.

See how Blackberry mobile phone handsets measure up to other smartphones such as the Apple iPhone 3GS in Which? mobile phones tests. 

Pay monthly price plans will be available on 18 or 24 month contracts.

Flexible Boosters 

New pay monthly customers will be able to choose from a range of ‘Flexible Boosters’ including: 

  • Unlimited texts
  • Unlimited internet on your phone 
  • International calling
  • Roaming, using your phone abroad
  • Unlimited calls to landlines
  • Unlimited calls to other T-Mobile customers. 

One Flexible Booster per month will be included in customers’ price plans, and T-Mobile customers will be able to choose different boosters each month if they wish.

When will T-Mobile tariffs change?

The T-Mobile Flexible Booster deals are available as of today. T-Mobile’s former Combi, Flext and Solo plans are no longer available to new customers.

Existing customers will be offered the option of moving onto one of the new tariffs or staying on their current tariff – if you love your Flext or Combi plan, T-Mobile has told Which? it won’t force you to change.

T-Mobile also plans to introduce a new range of Sim-only tariffs from £10 a month on a 30 day rolling contract – with Sim-only contracts there’s no handset included. 

T-Mobile’s Sim-only deals also include a choice of Flexible Boosters.
