I'm picking up B26 in Indian Land right now, and the connection is steady, but it keeps trying to revert back to B25. I thought B26 won't happen in NC for awhile, but Indian Land is in our SC suburbs.
I get LTE along US 521 often. I used to able to get a decent LTE along Fort Mill Highway up to the Honeywell location, and where those new apartments are being put up, but within the past two months, nothing at all.
I go to Planet Fitness off of University City Blvd often and the tower is on the other side of I-485 going towards Harrisburg, and I always get a decent LTE signal, but tonight there was no LTE. I'm probably wondering the same thing as you are.
