What should I do if the default SMS of vivo mobile phone is exchanged?

1, if the mobile phone comes with vivo mutual transmission, you can enter the settings of mobile phone-other networks and connections-vivo mutual transmission and turn it off. 2.vivo smart phones use mutual transmission software to transmit data, and both mobile phones need to install and open the mutual transmission software connection to transmit data. Specific operation steps (taking vivoX7 and Y67 as examples): 1. Go to the app store to search and install "mutual transmission" software, open the mutual transmission software on two mobile phones, and set nicknames. 2. One mobile phone chooses to create a group rent, and the other mobile phone chooses to search to join. Pay attention to the fact that the two mobile phones can't be too far away, otherwise they won't be searched. 3. Click the discovered device and select the connection. When connecting, pay attention to whether the transmission object is correct. 4. Select the file, and then click Send. Be careful not to pause the screen of the mobile phone when sending, so as not to turn it off in the power-saving mode of the mobile phone. 5. After another mobile phone receives the file, the file is located in: mobile phone storage/mutual transmission. Pay attention to the location of the file after the transmission is completed, so as to find it later.
