Windows 10: Why can i not add my phone number?

So I have been dealing with this since I got my new phone number. It will not let me add it. I will let me go through the process of trying to add it like entering the phone number, and verfiing it, and guess what I get the verification texts, then asking for my account password again like it is going to verify the number to my account then I get hit with "This alias cannot be added to your account. Choose a different alias." in red. I do not have the number I am trying to use on any other Microsoft accounts. I pay for realms on Minecraft Bedrock with the number connected to that, and it works

Blocking Cell Phone Numbers

Here's one way to get around the problem. It's kludgy but it should work.

Get a VOIP based phone service or a magic jack. For 24/7 access, you're better off with VOIP that uses an ethernet adapter, but that's up to the user.

The important point is to find one that lets you create your own "black list" of callers. Usually they will have both black and white list options and these are usually a subcategory under the "do not disturb" or similar feature.

The provider will usually let you create a second number for $5-10 per month. You'll use this for your cell phone number. If it is ever compromised, you can change it easily without affecting the base number.

Forward the second number to your cell phone and give everyone that one as your "cell phone" number. There will be a delay of a few seconds as calls get routed, but who cares. It's not like any of us is on Obama's speed dial right?

Now when you get assholes calling you, just add them to the black list.

You can also block calls w/o caller id this way if your cell phone co. doesn't already do that for you.

 

Trouble saving voicemail number

To access my voicemail it is my phone number, a pause and 4 digit pin.



I did the following steps:

• Turned off default voicemail number
• Added a , (for pause) at end of my phone number
• Added the 4 digit pin

I get the following error message We're having trouble saving your voicemail number right now. Try again later.



Any suggestions on how to correct this?

 

Supported phones for Windows 10 Mobile Insider Preview Mobile

Your list confirms my phone is eligible, Lumia 521. The windows Insider App fails after ~ 15 seconds, restores data and gives me error 80073cf9. I trouble shot this and went thru all the steps mentioned on several websites including MS without any luck. Short of a hard reset, this is where I am now. Suggestions appreciated.
