France's Carrefour is talking to Orange and SFR about becoming a mobile virtual network operator. As well as bringing competition to France's stale mobile market, the move could give Carrefour an mCommerce advantage by increasing visitors to its mPortal. However, its choice of allies might not be the best, since the two dominant mobile operators are likely to want to keep mobile charges high. Their smaller rival Bouygues may suit Carrefour better.
