It’s important to use the same Apple ID for Messages and FaceTime on all your computers & devices so you won’t miss an important text or call, no matter which device you have with you. And if you plan to use Handoff for phone calls and texts, use the same Apple ID for Messages, FaceTime & iCloud.
It’s best to start with an iPhone before moving on to iPad or Mac so that the mobile number can be used for Messages & FaceTime on them.
- Go to Settings and tap Messages.
- Tap Send & Receive and the Apple ID at the top.
- Choose Sign Out if it’s signed into the wrong account.
- Tap Use Apple ID for iMessage.
- Sign in with the correct Apple ID and password.
- Go back to the main Settings page and repeat for FaceTime.
