Rang up today to move over to sim only contract having seen the current Virgin 20gb/£15 offer. No faffing, said I needed more data than my current 2gb, that I'd seen the virgin offer. They offered up matching this and adding an additional 5gb data. Includes eu data and bt as other recent deals have. 12 month contract, though you can upgrade at any time. Couldn't have been simpler, all done in three minutes.
