does anyone currently have Metronet / Tmobile internet in the USA and using Opn

[DEC670airp414user]

I have been a Opnsense customer since i purchased my DEC670 appliance.  and each year purchased the business license as a home user i believe i am on my 3rd license.
long story short when i first signed up for Metronet fiber the Nokia ONT and my DEC670 would never stay connected.   I ended up Needing the service to work so i read that a static IP address would be the fastest route, so i signed up.
Metronet is now moving to Tmobile Fiber internet, and rumor is static IP addresses are going away.    which could cause me issues.

is anyone on this forum in the United States and fall under this same scenario but using the non static IP service/  CGNAT?    and is your service working with no alterations to Opnsense?
thanks
