WiFi calling on Warp

Been on USM for sometime. Recently moved from Darkstar to Warp on an unlocked Samsung Galaxy s25 Ultra.

WiFi calling worked fine on Darkstar but is not getting activated on Warp. When I flip the toggle, it instantly gives an error “Unable to activate WiFi calling at this time. Please try after some time”. Spent a long time working with web chat and via email and it feels like I’ve exhausted every single device side troubleshooting step possible. Did a completely brand new eSIM profile, reset network setting several times, turned off DNS, cleared network cache, reset WiFi settings etc.

IMS registration status is actively On which tells me that the phone is working fine with the network. Data works fine, calls work fine. What I’m not getting is the pop up to enter my E911 data when I try to activate WiFi calling. Not sure if this is a Verizon issue or something else. Would appreciate any help
