    Is the Time/Date correct on your phone?

    It sounds like a wifi calling issue. Did you setup your address on your tmobile account? You can do that for the wifi calling or just disable it and that should go away.

    If you don't have a valid 911 verified emergency address set on your T-Mobile account WiFi calling will not work. Easiest way to set that up is via your online account. You can also call T-Mobile customer care or go into a T-Mobile store to have it applied.
