They've been selling with this allowance as a key feature...
It is impossible to see the Internet Provision as a mere addendum to the two year contract when the advertising of their internet enabled, and especially android, phone contracts makes a huge play on the included internet!
I was looking at phone contracts and bargains/deal heavily over the past few weeks and a key selling point of the _direct_ t-mobile contracts was that they gave you 3GB on a android phone (or 1GB on some others) INCLUDED in the contract price. Plus the agreed minutes/texts, and Plus one other EXTRA (such as unlimited texts). This made their direct contracts about £5pm cheaper than those from resellers AND on the better phones gave you a 3GB FUP instead of a 1GB FUP. Indeed that FUP is still here: http://www.t-mobile.co.uk/services/uk/fairuse/?WT.mc_id=fup#fup2
While they did not define the limits on the sales page the FUP was unusually clear about things, and you were encouraged to read it. That to my mind makes the FUP an important part of the contract, and one would not expect it to be reduced to 1/6th of its prior value during the contract on a mere 30 days notice. Especially if anyone bought their 2 year contract in the last month. Bait and switch indeed. That's like selling you an annual train ticket and then cancelling most of the trains.
They are trying to rely on the Internet Plus bundle being an "Additional Service" as defined in their term: " an optional/extra Service which can be added to Your Account, the Charges and terms and conditions for which are set out in..." They may not get away with this since the Internet Plus booster is not 'buyable', and is really a fundamental part of those contracts. You can only remove it and they warn you of your terrible fate if you do.
As another commentator said this may well be the fruity Orange, wagging the t-mobile dog. I had previously been shocked at _how low_ orange's FUP was with many contracts only receiving 250MB/month. An android or apple phone might eat that in days, or hours!
And remember that any above contract usage is charged by almost all the phone companies at an outlandish rate often higher than their PAYG! Even phone minutes, let alone mobile internet. T-mobile's fup actually implies that they will block or throttle net use ("If you use more than your fair use policy amount, we won't charge you any more, but we may restrict how you can use your plan, depending on how often you go over your amount and by how much"). Most switch to charging 60p-102p per day (with another FUP) or even something high per MB.
Just confirmed (8.47pm 10th January 2010) and they are still marketing the bundled "internet Plus" with 3GB FUP. I wonder if perhaps they are targeting those who are "out of contract" with this new term.... Or they are targeting business users relying on this:
"2.11.1. If You are a Consumer and the change of terms and
conditions is not of material detriment to You or You are
not a Consumer, We will send You Written Notice 30 days
before the terms and conditions are due to change. The
new terms and conditions will automatically apply to You
once that notice has run out.
2.11.2. If You are a Consumer and the change is of material
detriment to You, We will send You Written Notice 30 days
before the terms and conditions are due to change. The
new terms and conditions will apply to You once that
notice has run out, unless You terminate Your Agreement
with Us within that notice period. If You do this You won’t
have to pay any Cancellation Charge that would otherwise
apply, see point 7.2.3.2."
(Sorry that's so long. So relieved we didn't take a new contract now!).
