"SME address book" service refers to a value-added service provided by mobile to enterprise users, which can integrate the internal address book of enterprises and facilitate internal communication. When using this service, enterprises need to pay a certain service fee to mobile according to certain standards.
"Group V network" is a voice communication service, which can classify the telephone numbers in an enterprise into a group number and realize the advantages of internal free dialing and external unified dialing. Enterprises also need to pay a certain service fee to mobile when using the "group V network" service.
The specific charging standard may be different due to factors such as region, enterprise scale and service content. I suggest you consult your local mobile business hall or call customer service for manual consultation.
