http://www.virginmobile.com/vm/gener...r.sm068#Virgin Media Mobile Acceptable Use Policy Pay Monthly
For new & upgrading customers from 24 January 2013: If your tariff includes data, then this 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".
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 between midday and midnight. 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.

"We currently don’t offer tethering service. If your tariff includes unlimited data, that will cover mobile internet services and data consumption of the handset. It does not include using your handset as a modem to connect other devices such as laptops and tablets."
