Carrier will introduce a service that combines contacts, phone, web

Chinese telecom operator China Mobile Ltd, which has been hit by mobile instant-messaging tools such as WeChat, says it is determined to fight back by introducing an integrated communication service this week.

The company unveiled a plan on Wednesday at the Mobile World Congress 2014 held in Barcelona, Spain, saying that it aims to help consolidate the functions of the phone, contacts and messages in customers' mobile phones by upgrading them into a new format.
