I'm happy to report that all is good now.  I only wish T had sent a blanket email out the very minute they fixed it instead of letting us have to figure it all out for ourselves. It would have saved a lot of aggravation.

Carry on. LOL.

I still haven't had time to call them. Hopeing for good things

I just spoke with Louis at support - there seems to have been an update pushed out on 2/27/2024 (he couldn't confirm), and all I had to do is reset my modem/router and I am able to use my VPN again. I have AT&T Global Network Client VPN and the Sagemcom model modem/router.

Hopefully this saves others some agravation.

One of my problems isn't device specific. With the SIM in other modems and phones one of the lines is still throttled to 0.01mbps both up and down.

I’ll report back when I finally do have time to call.

TLDR; The guy that actually knew his stuff said there are know issues with specifically the Sagemcom unit and VPN usage. I still have yet to test his theory, but how others here have mentioned adding a double NAT router or changing your devices MTU make sense. So this seems to be isolated to the Sagemcom unit. You should be able to go to any store and request a newer (Nokia) or older unit, both other which do not have issues with VPN. You will be charged an activation when switching units, but should have luck calling into support for a credit. Note billing issues cannot be handled in the store and only over the phone or internet with overseas support.

15 minutes in, I’m on my 6th transfer to the same department that can’t handle business accounts.

So that’s 10 minutes listening to pop music on full blast.

7th transfer, got an English speaking rep in NC. But he can't help with business either. Told me the online account side of things for business had been royally messed up and they don't even have the resources to know how to contact the business center. I could tell he was really trying and did give me some useful information as to the numbers of the different lines, and what actually happened here.

So here’s what happened:

I have had a business account with T-Mobile for a long time. I had many lines on this account, all with the same exact service.

When I get the home internet units on this fully unlimited plan, I remove the SIM cards and use them in enterprise cellular modems (the ones used in military and law enforcement applications). They are used as a redundancy to VPN tunnels for voice and point of sale applications.

Whoever added the last line selected a different 100GB capped service - so that’s one issue solved.

Then he indicated there are issues with VPN and specifically the Sagemcom unit.

He warm transferred me to business billing. They then proceeded to give me access to an online business account as a master admin that wasn't even my company. LOL

TLDR because I’m tired of typing, what a joke, but after a hilarious and painful 90+ minute phone call, I myself was able to get things sorted out for T-Mobile.
