Awful company

Samsung handles the warranty of their products, not AT&T. If Samsung chooses to have you mail it to them for repair, that's how it works. Simple fix, don't buy a Samsung phone next time. Just as an FYI, Apple does the same thing if you don't have an Apple store anywhere nearby.

That won't work!!   The only solution is replace the phone.  After 5 months they finally relented, thank you.  It's obvious these phones were slated for Verizon.  I got the replacement and noticed several apps are different.  Text, email, iheart are all back what they used to be among others.  I thought they were upgrades, nope.  It's Verizon's specifications to Samsung.  No matter how many "fixes" tech support tries it won't work.  There is an internal conflict with AT&T and Verizon.

Utter nonsense 🤦🏼‍♀️

So you purchased a phone with an AT&T box and an AT&T boot screen and yet your insisting the phone was made for Verizon?  

Pardon a snicker on my part.

Samsung sells its phones all over the world. And what it sells in the USA is similar to what Apple does. It sells through carriers, a USA universal locked/unlockable phone. Whether it's sold through a third party like Best buy, or directly by the service provider, it is unlockable and universally accepted by another provider. However if you purchase directly from AT&T, it came with AT&T software on it out of the box.

   Once unlocked, and updated, it will convert software when you insert a SIM card from one of the other major service providers.

If Samsung repaired or replaced your device it is now refurbished it may have parts and software that are different from the original phone. It should still be a universal USA device. It may now be universal and unlocked rather than the universe lockable version. That was up to Samsung to determine what they were going to send you.

AT&T does not make phones. They sell branded phones. If there is a defect in the phone it is entirely on the manufacturer, not AT&T.  Blaming AT&T or Verizon or T-Mobile or any other retailer for a product they sell - but did not make - is utterly ridiculous

Since it's utter nonsense explain why the phone gave me the phone number to Verizon's tech support.  I still have a screenshot

No doubt that is a Verizon CS number BUT you are connected to ATT at the bottom.  Did ATT or Verizon send you the phone?  ATT visual VM does not work like regular VVM as you cant read text versions.  

Bought the phone new at an AT&T store where they installed the new sim themselves.  I've never had Verizon and never thought about using them so it's really strange for it to pop up.  My problem with AT&T on this is they knew there were S22s with this exact same problem back in September and I got the phone 2 months later.  They should have issued a memo to their tech people if this happens to someone to immediately replace the device.  I spent over a total 20 hours on the phone with tech going through the exact same process everything and someone should have known it won't fix the problem.  

  This isn't an AT&T problem or a Verizon problem It's a Samsung problem they are the ones who program the phones put them in a box marked for the carrier and send them to the carrier for the carrier to sell the customers.

If AT&T gets a batch of phones and buried in that batch of phone somewhere are defective phones that came from Samsung how are they supposed to know?  (They don't)

And since both carriers cell phones locked out of the box to that service provider it would be impossible for you to have purchased a phone that was supposedly programmed for Verizon, it would not have worked.

Fyi:  The VVM is a known phishing scam

Unless you called tech support, they have no reason to call you.  And since you are not a Verizon customer you had no reason to call them..

I've searched the differences I've described previously and what I see is it's truly what you'd get with Verizon.  There are differences between AT&T and Verizon setups.   It was a phone set up for Verizon from Samsung.
