I have a metropcs phone and an trying to et wifi calling to work. 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?
