Can peer-to-peer SMS on mobile network only send SMS to one number? thank you

Peer-to-peer SMS refers to the SMS between ordinary numbers, such as mobile phone number, Unicom phone number or PHS, and Dalingtong is a peer-to-peer SMS. The short message in the network refers to the mobile phone number sent to the mobile phone number, which is the short message in the network.
