Earlier, we covered fixing the “Waiting for Activation…” issue in iMessage after our triumphant (we're not going to be humble about it!) success with it. And then came the FaceTime thing. On one of our iPhones, we're still trying to activate FaceTime but where it has gotten activated, these are some of things we had to try.
Getting rid of FaceTime's activation errors or “Waiting for activation…” problem isn't all that fun. While it sure is going to go away sooner or later, you will have to try a dozen different things to set them right. We're just trying to put out pointers here as to what you can try to get rid of the problem.
The first thing you'll need to check – if FaceTime isn't working – is to find out if FaceTime's blocked in restrictions.
Go to Settings -> General -> Restrictions and then Disable Restrictions. If that's not possible due to certain other reasons, make sure FaceTime is turned ON in the list of ‘Allowed Apps'
Try a hard reboot. Hold the power and home button for a long time till the screen goes blank, and then power on in the usual way. This will restart the iPhone. This has the capability of fixing Wifi issues, network jams or sometimes, carrier network problems.
Sign-out Apple ID / Sign-in
Within FaceTime, sign out of your Apple ID and sign in again. In many cases, this is known to fix the FaceTime activation issue. But we've had no luck with this. In fact, in one of our attempts, this created another problem: we couldn't sign in to our Apple ID again.
Reset Wi-fi settings
You might need to reset Wi-Fi settings if in case there's an issue with your network. Now, how do you find out if there's an issue with your Wi-Fi? Normally, you don't. You just try.
Go to Settings -> General -> Reset -> Reset Network Settings. The iPhone should reboot and then bam! If you're lucky, FaceTime will send the activation message and after a while, it should get activated with your number and Apple ID listed underneath.
Phone Number details
Oh, make sure you've got the right number listed in your ‘My Number:' feature under Contacts. To set this, you'll have to navigate to Settings -> Phone -> My Number and enter the number you use on the iPhone.
Date & Time, Country Settings
Furthermore, make sure your Date & Time settings are in proper order. If the Date & Time is set to automatic, make sure the time zone is rightly selected and the time displayed is correct. If not, set manually.
Within iMessage and FaceTime, you have the option of changing the location of your Apple ID account profile. Tap on the “Apple ID:” field and then tap on ‘Change Location'. Set this to the correct location.
Well, this is not unorthodox even if it sounds so, but remove that SIM card and place it again. If it doesn't work, change that thing and check with other SIM cards (if you've got an unlocked iPhone). In many cases, the carrier has been the culprit, blocking the activation/confirmation message from being sent or processed.
Ah, that old story again. If nothing works, restore. Make sure you take all the backups necessary and then restore from iCloud or iTunes as you see fit.
