Can I send text messages on other mobile phones?

If it is an Apple ID, it will be synchronized without turning off synchronization. You can choose to re-register an account or turn off iMessage to prevent synchronization. Take the Iphone6 Plus as an example. If it is other old versions of the system, the interface display is different and the operation steps are the same. First, open the "Settings" application on the main screen of Apple's mobile phone, find the "Information" column in the settings list, and click to send SMS, video, etc. , with very high security. IMessage is different from SMS/MMS service of operators. Users only need the data support of WiFi or 3G network to complete communication. Whether the other party is playing a game or locking the screen, if both parties are using iMessage, you can even see the other party's talking state.
