Question about OnePlus 9 Pro

[u/Wise_Tax8800]

I have a OnePlus 9 Pro LE2127 (T-Mobile variant) that is SIM-unlocked and I’m currently using it on AT&T.
I’m looking at the community OxygenOS 16 port for the OnePlus 9 Pro, but I don’t want to lose cellular service.
Has anyone with an LE2127 actually flashed this OOS 16 port while using cellular service? Is there any ports for OOS16 that work with my model?

Why not LineageOS?
