I have been with Virgin since there days as blueyonder and i am really happy with the service, I switched to Virgin mobile on a 2 yar contract in April 2010, 400 mins, unlimited texts etc etc all for £20 a month, i asked for an upgrade last week and lo and behold i had the Samsung Galaxy 2 smartphone within 24 hours, they had to sort my contract to suit but i am paying £26 monthly for 600 mins and 1g of internet and unlimited use of Spotify. I would definately change, they piggyback (use other networks) with t-mobile and now Orange at no extra cost if you find yourself needing to use 1 of the other so you are invariably always able to use your phone. hope this helps you make your mind up.
