At work it works great. I registered my 911 adress and it connected perfect. It is when I am at home when I have the issue. Ihave a tp link arcer C9 router and a netgear dm200 dsl router. When I try to connect it gives me a REG99 unable to connect error?

Have you checked your network settings to make sure that any ports or services needed for WiFi calling aren't being blocked? I have that issue with networks that actively block this kind of traffic (like work and now, believe it or not, most hotels abroad), but no problem with 'normal' networks (my home WiFi, public hotspots, etc.).

One my OnePlus 3T I had to add wifi calling to my plan even though it's free. Then I restarted my phone and everything worked good! Give that a shot. Just contact tforce via Twitter DM for the best and quickest results!
