My best buy had one of the Mate 9's in stock so I grabbed it to do some testing. I have Verizon for work and At&t for personal. The phone has the 3g CDMA2000 1xEV-DO band which I figured should work for calls and texts on Verizon just like the OnePlus 3 does. I figured Id pop the sim into tray 2 and at least be able to make a call. Verizon Wireless shows up on the notification bar and I have full signal bars but when I try and make a call it says "dialing" for about 45 seconds then says mobile network not available. Im wondering if this is a possibility to get it working like the OnePlus 3 that has the same band. If I can at least get calls this phone is a home run for me.
