T-Mobile price plans come with Flexible Boosters. This Internet plan is configured with the Unlimited Internet Booster.
This can be switched to any of the other Flexible Boosters such as Unlimited Texts, Unlimited Landline or Unlimited On-net (for calls to T-Mobile phones) every 30 days, however Internet charges will then apply.
If you want more from your plan, a range of additional Boosters can be added for £5 a month each, and changed or cancelled with 30 days notice. Choose what suits you.
Inclusive minutes are to UK mobiles and numbers starting with 01, 02 & 03 (excl. Jersey Guernsey and Isle of Man). Texts are to the customers of UK Mobile Networks. Voicemail isn't included. Unlimited Internet has a fair usage policy of 1GB a month.
You can purchase a package that includes 300 cross-network mins + 300 texts + Unlimited Internet Booster and a free Nokia 1661 for £160 for the duration of the contract (24 months) and after a £200 automatic cashback.
