When you subscribe to this service and use this function, your main number and sub-number will switch automatically according to the network accessed. When you register with CMCC or a third-party’s network, your registered number is your main number; and when you register with the partners’ network, your registered number is the sub-number.

Mobile phone customers in Guangdong, Shanghai, Beijing, Fujian, Jiangsu and Zhejiang can enjoy this service.
