China Unicom expects ARPU for its mobile and broadband services to drop in 2H09, but hopes income from its 3G data services will offset part of the decline, reports Reuters. The operator had 138.83 million total mobile subscribers as of April, up from 137.69 million in March. Unicom, which holds the sole license to operate WCDMA technology in China, officially launched 3G services on 17 May.
