Nokia saw sales rise by 18% in China during the quarter as it secured contracts from a number of Chinese carriers that are preparing to upgrade their networks. Both China Mobile Ltd. (NYSE:CHL) (HKG:941) and China Telecom Corporation Limited (ADR) (NYSE:CHA) (HKG:0728) chose Nokia to upgrade their networks. Now Nokia is looking for even more network upgrade orders so that it can increase its margins and also raise its debt rating out of junk status.
