T-Satellite 911 Signup is Saying My iPhone is Carrier Locked... It Isn't

I've used this iPhone SE 5G on AT&T, Verizon, and T-Mobile with no issue...

Currently I need it on Verizon, so I wanted to activate the $0 T-Satellite 911 eSIM.

The site is refusing, saying my iPhone is locked.

iPhone SE third gen is listed as supported. Anyone know what to do here?
