Virgin Mobile - two carriers?

[Trapper]

Anyone know why Virgin mobile has two carriers in the UK - one as Virgin (cap V) and the other as virgin (lower case v) which seem to randomly swap between the two.

 

Being anal I want my carrier to have a captial V not a lower case! And I'm interested as to why they have two - is this two virtual networks on two different primary carriers?

A wild guess, but perhaps 'V' means you are on T-Mobile's network and 'v' is Orange's?

 

Initially, Virgin Mobile in the UK used the network coverage of Mobile Operator T-Mobile and have been doing so since their establishment, however, following the merger of T-Mobile and Orange UK to form the brand "Everything Everywhere" in Britain, customers could begin to take advantage of Orange's broadcasting signals in addition to those of T-Mobile from Autumn 2011.
