Send a message to a group or business on iPad
Use the Messages app

Watch together with your friends in FaceTime
Using SharePlay in iPadOS 15.1 and later, you can stream movies and TV shows while on a FaceTime call with friends. With synced playback and shared controls, you see and hear the reactions of others on the call. The volume automatically adjusts, so you can keep talking while you watch.
Note: Some apps that support SharePlay require a subscription. To watch a purchased movie or TV show together, all SharePlay participants must have purchased the item. Some movies and TV shows may not be available to SharePlay across different countries or regions. FaceTime, some FaceTime features, and other Apple services may not be available in all countries or regions.
