Seems to be a common problem for many, many Android phones. Wi-Fi calling and texting is not working "Error 081" appearing in connections. Reset phone, disconnected and reconnected to Wi-Fi, can't play with setting as I am at work, not my wi-fi. Deleted Mint's provided APN and reconfigured, nothing.
Anybody find a solution that actually works? If I can't make wi-fi calls/texts I'm going to have to find a new provider
