What utter crap this author spouts!!!
"Virgin and Tesco have very successful MVNOs, but it would have been difficult for Carphone Warehouse to have operated an MVNO while claiming to be independent and selling contracts on the other networks. This problem would disappear with the forthcoming division."
Excuse me but
Talk Mobile
Fresh Mobile
Mobile World
are all MVNO's that belong to Carphone Warehouse
Try reporting the facts!!!!!
