Hey @haircre8tor, I hope you're doing well.

 

While the Note 21 Ultra doesn't exist (yet...?), I assume you're talking about the Galaxy Note 20 Ultra. If you're an AT7T user (regardless of the device being an unlocked unit, this is a known issue with the latest update. To resolve this, you will need to edit your APN settings.

 

To do this, you will need to go to: 

  1. Open the Settings app>Connections>Mobile Networks>Access Point Names>Add>
  2. Fill in all applicable fields based on the chart provided by AT&T (here). You will need to scroll down to the Android portion of the page and use the information under the "Smartphones" column.
  3. After entering all of the APN information, press the menu button on the top right>Save

You should be up and running and can send MMS messages. For good measure, I'd recommend a reboot after saving your added APN.

 

I hope this helps!

It's in the link in my post where it says "here."

If you're unable to press the link, simply Google search "AT&T APN" and select the article titled "How to program your data settings for a non-AT&T device."

This worked for me. Since this is common knowledge, Samsung should update this in the work through on the website. I almost took my phone in for warranty but gave it one last search. Thank you!
