On Monday 10 January 2011 we announced that, in line with the rest of the industry, T-Mobile would be reducing its Fair Use Policy for data usage to 500MB a month for all mobile phone customers. Following a further review of our policy, these changes will now be introduced from 1 February, to new and upgrading customers only - not existing customers.
There will be no change to the data packages for existing customers for the duration of their contract and we apologise for any confusion caused. The revision to the Fair Use Policy is designed to ensure an improved quality of service for all mobile internet users."
