I have an HTC M9 and HTC Ten that all connect on Bands 2,4, and 13. They switch between
those bands frequently. My U11 however only connects on Band 13 and is slow and occasonally
drop the signal. I've called HTC about this issue, and their reply is that that Bands 2 and 4 are
available on the U11, but not activated by Verizon software. Please can your engineers send out
an OTA that will enable WiFi calling and Bands 2 and 4?
