How to open point-to-point SMS in China Mobile?

Point-to-point refers to mobile-to-mobile, that is, both the sender and the receiver are numbers of China Mobile. If your package fee includes free SMS, such as M-Zone online chat package, you don't need to open point-to-point SMS. If the package fee does not include SMS, you can directly call 10086 for manual customer service, or you can open it yourself in the mobile online business hall. The customer service representative of Chongqing Mobile 10086 will answer your questions.
