No 4G-LTE service
I have a Verizon HTC One (M8) Windows Phone using a Consumer Cell simm card. CC btw: uses AT&T. All services work - voice, text -2g - 3g but except no 4G LTE. Looking at a web page that lists who uses what, ATT is listed as using the lower half of 700mhz while Verizon uses the upper half. Hardware wise there is no electronic differences between the Verison, ATT or any one else. What is needed is a software upgrade. Is there a way to get the software updated to enable 4G on ATT? If the phone was Android based I wouldn't be here asking, but since it's Windows based the process may not be possible. I spoke with tier 1 support and they seem to think that all I'd need to do is swap simm cards with a ATT proper simm card the the phone will automatically download and install what ever firmware or updates are needed.
Can one one validate this? Thanks
