The "manage my watches with NumberSync" page only displays my primary line, not my secondary.

Thanks for following back up, @TurkeySandwich.

Each wireless number on your account that uses NumberSync should have its own ID. This ensures that all calls sent to and from a synced device are linked to the right number.

You can use the myAT&T app to Set up your 2nd ID for NumberSync for your Razer Phone 2.

Hi @TurkeySandwich,

Thank you for reaching out. We want to take a close look into this.

In order to better assist, we'd love to know;

• is the Razer Phone 2 line in the same account as your Galaxy S10+
• is the watch you are trying to pair already paired to the Razer phone in the past
• is the line active and in good standing in the account
• how long has this been going on

Please note that Numbersync works for android and non andoid devices alike.

Let us know, so we can assist further.

The Razer Phone 2 is on the same account. The account is in good standing, the line is active. The brand new LTE Galaxy Watch 3 is bluetooth paired to the Razer Phone 2. 

I have attached a screenshot of the webpage that is opened by the Watch when I attempt to NumberSync it. As you can see only the Galaxy S10+ and the Watch 3 currently paired to it are displayed. No Razer Phone 2 or the second Watch 3. 

That was in fact the issue. Thanks for your help! 

You're welcome, @TurkeySandwich!

I'm glad I could help with the solution, & hope you enjoy both Galaxy Watch 3's.

You're always welcome to create new post's, & share in AT&T Community Forums. Take care!
