- If you're using Wi-Fi, make sure that your local Wi-Fi network is using the recommended Wi-Fi settings.
- Sign in to your account and ensure that the primary email address and alternate e-mail addresses have been verified. If verification is pending, follow the instructions in the email Apple sent to that email address to complete verification. Or remove the e-mail addresses from the account.
- If your Apple ID isn't an email address, you can change it. The Apple ID that you're using to activate FaceTime or iMessage must be an email address. Find more information on how to change your Apple ID.
- Tap Settings > General > Date & Time. Make sure that your iPhone is set to the correct time zone. If Set Automatically is on but the wrong time zone appears, turn Set Automatically off and choose the correct time zone, date, and time.
- Enable iMessage and FaceTime while connected to a different Wi-Fi network (in a different location) if a cellular data connection is not available.
