HTC "All New One" (HTC M8) hits FCC: likely coming to all four major US carriers
Before we examine them, though, we ought to mention that one of these six is the NM80P6B100 model, which looks like the international version of the new One with support for 4G LTE on band 7, popular across Europe, Asia and other territories.
Then, there are four different HTC “All New One” models - for Verizon, AT&T, Sprint and T-Mobile. The difference between them seems to be only in the connectivity, as they support different 4G LTE bands. Model NM80P6B120 is the AT&T one, NM80P6B200 is for Verizon Wireless, NM80P6B700 is the Sprint-bound version, and NM80P6B160 is for T-Mobile. The last version, carrying product ID NM80P6B130, supports 4G LTE bands 4 and 17, which are frequencies commonly supported by regional US carriers.
Interestingly, the FCC filings for all these models reveal that the commission has received the device samples months in advance, on October 23rd of 2013, and the actual testing of the models happened between November 25th and December 4th.
The last thing that we can spot on the images from the FCC filing for HTC’s “All New One” is the new positioning of the 3.5mm headset jack that now seems to be on the bottom of the handset. The current HTC One has its 3.5mm slot up top.
Summing it all up, we have all evidence suggesting that the new HTC flagship will arrive on all US carriers, and that's good news. HTC has set the official unveiling date for the handset for March 25th, so it won’t be long until we learn more about the company’s next big thing.
