Don't know exactly how to go about it, but can Crackberry Kevin and his team put an on line petition together so that AT&T will "whitelist" the Keyone so we can use full features, including Wi-Fi calling and not have to spoof IMEI to get VoLTE and LTE?
The Keyone is a great phone but without this access, it is crippled for those of us who have bad reception at home or work.
