iMessage and FaceTime error in Activation

Mine FaceTime also not work.it says to activation  why? How to do it ?? Please anyone tell

Well, I did every reasonable thing called for in the replies. Thanks for everyone weighing in and trying to help. HOWEVER, Message is finally working (although it stopped again for a day), but not FaceTime. Again, both are fine on my iPhone. This problem (or similar) seems to have occurred multiple times in the past few years. And why doesn't FaceTime recognize my Apple ID which is working for every other application? So now the question is: HOW LONG DOES THIS HAVE TO CONTINUE BEFORE APPLE FIXES IT?

FaceTime got deactivated… can’t understand why. And now unable to activate. Apple is not helpful, on asking, Apple puts me to community help. Why Apple can’t help directly? Why should I go through hundreds of advises by community members?

I am also having issue with FaceTime. I did what was asked, turn off iMessage and FaceTime, rebooted the phone and I still get a message to sign in to FaceTime when trying to FaceTime someone. I can FaceTime my husband but not my bff.

Having performed all of the above, what information was shared with you by Apple Support when you contacted them?

When I send a message it keeps on saying not delivered

To use iMessage or FaceTime, you'll first need to activate them on your iPhone, iPad or iPod touch. If you receive an error message during the activation process, follow these steps.

When activating iMessage or FaceTime, you may see one of these messages:

• Waiting for activation
• Activation unsuccessful
• An error occurred during activation
• Could not sign in. Please check your network connection.
• Unable to contact the iMessage server. Try again.

Check your device settings

1. Make sure you're connected to a mobile data or Wi-Fi network. 
2. If you're using an iPhone, you'll need SMS messaging to activate your phone number with iMessage and FaceTime. Depending on your network provider, you may be charged for this SMS.
3. Go to Settings > General > Date & Time, and make sure your time zone is set correctly.

Turn off and restart iMessage and FaceTime

1. Go to Settings > Messages and turn off iMessage.
2. Go to Settings > FaceTime and turn off FaceTime.
3. Restart your device:

• • iPhone
  • iPad
  • iPod touch

iMessage or FaceTime still not activated after 24 hours? 

It can take up to 24 hours for iMessage and FaceTime to be activated. If you're still experiencing the issue after 24 hours, follow these steps:

1. Make sure your device is running the latest version of iOS or iPadOS.
2. If you're using an iPhone, contact your network provider to make sure you can send and receive SMS messages.
3. Make sure you can send and receive SMS. If a prompt appears stating: "Your network provider may charge for SMS messages used to activate FaceTime and iMessage", tap "OK" to allow possible SMS charges.
4. Contact Apple Support.

If the email address is incorrect, you can update it. Then click Resend next to the email address you want to verify.

FaceTime isn't available in all countries or regions.

My daughter’s phone just did this and I turned the wifi off and as soon as I did that, the iMessage and FaceTime activated and was working fine again. I turned the wifi back on it’s still working. Hope that helps!

FaceTime and Messages work fine on iPhone 11 (all apps/system up-to-date). Messages works on 2019 MacBookPro running the latest Ventura update. However, Facetime screen opens on Mac with "sign in to activate" with camera on but won't recognize Apple ID password (spins) accepted on everything else. Instructions say "sign out" but there is no option to sign out. "Settings"and "Turn FaceBook Off" options grayed out on pull down menu. Message after long-time spinning: Apple ID PW on FaceTime and iCloud different. Apple ID PW works on everything else(???)

My FaceTime isn’t working

And yes I did turn them both back on. I should have added that when it asked me to sign into FaceTime. It takes me nowhere.
