T-Mobile WiFi calling not working

[colton groters]

All was well when I switched from cricket to TMobile and then I ported my number... I get a reg99 error after it tries to enable WiFi calling, any help would be greatly appreciated.

Read the following forum posts from T-Mobile support. Appears to be a WiFi router problem.
