Not getting Text/Sound notifications on Lock Screen or when screen is fully locked/off? SOLVED!

This is insane. I spent hours chatting with apple support, then they called to "troubleshoot" and told me there was no information on troubleshooting for this issue. Ridiculous. Suggested I go to the Genius bar to figure it out.

I appreciate you putting a solution on here. Unfortunately it didn't work for me.

Someone please explain the point of muting messages when your phone is locked. The entire point is to NOTIFY you.

This is insane! I kinda have OCD tracking all of my annoying issues with apple products like these. I just spent a half hour with a senior specialist.

They were clueless. However, after some testing I finally figured it out.

You won't get the alert on your phone when it's locked or closed (black screen) if you have an iwatch and the notification settings are "Mirror My iphone". Turn Iwatch notifcations settings to "Custom" and it should work now.

My iPhone was doing the same (iPhone 13 pro max). Dead air and the lock screen wouldn't even light up when receiving a text notification... Watch would haptic and ding, but it's hard to feel and very quiet when working around any sort of noise at all.

Found the issue to be on my iPad.... This is ridiculous. The issue was solved same as above. I had to remove my icloud mail address from my iPad message settings in order to get my phone to notify me when the lock screen was on. Frustrated for 2 hours for missing notifications.

You can have multiple Caller IDs for iMessage/FaceTime on your device with iMessage/FaceTime.

This can be achieved by changing the Caller ID as shown in the GIF below. (Made on iPhone 6 iOS 12.4.5)

Change the Caller ID before making a FaceTime call. Enjoy privacy...

Caller ID is same as Reachable At IDs

In Order to add more Reachable At IDs (Refer to Picture at the bottom), Log into https://appleid.apple.com with your Apple ID credentials. Under Account Section Click Edit and Add as many as Reachable At Phone Number or Email IDs

My phone was not making a text notification sound when it was locked but did while it was unlocked. Uselecting my email address in the "Send & Receive" setting did fix this issue for me. There clearly is some problem related to message sounds and having an email address selected.

Please see the pic below for understanding what that email ID / Apple ID does for an iMessage. That email ID cannot be used for Sending SMS but surele can be used for iMessages.

Having an email address selected there does not mute messages. So, unselecting it will not unmute them.

Do you have an Apple Watch?
