Are you a heavy data user and current on one of Virgin Mobile's Unlimited Data plans? Well as it turns out, the data is not quite unlimited and its restristed. Read the quoted section of the their recently updated Acceptable Usage Policy below. It turns out that they cut the data speed after 3.5GB. They have been cutting my speed for the past few months but at least now they have the guts to back it up. BEWARE!!!
"Virgin Media Mobile Acceptable Use Policy Pay Monthly
Virgin Media’s mobile services (“our services”) are for private individual use only (i.e. not for business or commercial use). As such, you must not use our services in any way that is not in keeping with that reasonably expected of a private individual.
You are liable for all use of all accounts in your name, irrespective of use without your knowledge and/or consent.
Further, you must not use our services in any way that is unlawful or illegal or in any way to the detriment of other users. You also must not allow anybody using our services provided to you in any way that is unlawful or illegal or in any way to the detriment of other users or the network.
Data usage on some Virgin Media tariffs is for mobile internet services and data consumption actually on your handset. It does not include using your handset as a modem to connect other devices such as laptops and tablets - also known as "Tethering". Please refer to your terms and conditions and other communications from Virgin Media to check whether this applies on your tariff. This applies to all new and upgrading customers since 24 January 2013.
Virgin Media reserves the right to impose network protection controls which may reduce your speed of transmission if your data usage is excessive and not in keeping with that reasonably expected of a private individual.
For customers who joined Virgin Media after 25 June 2012 excessive use over 3.5GB of data per calendar month will result in their maximum bandwidth being restricted to 3G speeds (384kbit/s downstream, 200kbit/s upstream) on our network. For customers who joined before 25 June 2012 excessive use over 2GB of data per calendar month will result in this restriction being applied. This policy will apply until the end of the calendar month, when it will be automatically removed. We reserve the right to review these usage levels from time to time. At this reduced speed, customers will still be able to browse web pages, send/receive emails, and stream audio and video all at 3G data speeds, but peer-to-peer and large file downloads/uploads will be slower than normal.
As an example, a customer would have to watch over 16 hours of high quality video before that threshold is reached. Typically far less than 0.25% of our customers will be affected on a monthly basis."
