The minimum call charge is now 10p, up from 5p (which was introduced two years ago). What's more, they have changed the rule regarding the first five minutes of each day (which are billed at 15 p/min, before the charge goes down to 5p): Only calls to UK numbers (mobile and landline) will be considered.
It seems Virgin, under its new ownership, wants to make its prepaid service less attractive, now that it also offers contracts. There is also still no mention of the new EU roaming rates.
