    It may be more supported than you think...

    The process described in the XDA thread regarding enabling LTE bands works for Band 12.

    I used Albirew's method and chose the values for band selection provided by an app from the play store called "Qualcomm NV Calculator".

    YMMV.

    Thanks for testing this out.

    Did you actually get to see Band 12 work? What Location?

    I am running on Band 12 right now according to the LTE discovery app. I am in the Seattle marke which seemed to have just activated the frequencies. I have been watching the regulatory approval process closely and the license transfer just went through.

    I have noticed that the phone is significantly warmer than usual in the past few days. I am going to have to figure out if the temp change is due to the ROM I am running or the radio using a different band.

    According to my research, Band 12 will not be in Denver for a while due to a station move that has not happened yet. If you have a Channel 51 on OTA television, then the band will be blocked for wireless service.
    Fortunately, it is active in Colorado Springs which is only 60 miles from my house. I will see if I can get a good excuse to drag the Mrs. down with me to see if I can do some testing.

    Yea, I'm in Denver. Channel 51 applied for a frequency change a few months ago. I herd it usually take 6 to 12 months.

    I just got it too! Currently in the New Haven County area. I was upset thinking it wouldn't support it at all but nope, here it is it seems. Band 12! There's the LTE Discovery screenshot and a speed test.

    My best guess right now is that it was enabled in the last OTA update for the OPO.

    All wireless signals use certain radiowave frequencies to communicate data. When it comes to mobile phones, these frequencies are given in the follow "bands" (range of frequencies) as listed by this article: http://en.wikipedia.org/wiki/UMTS_frequency_bands

    Basically what the OP is concerned about is that the OPO doesn't have a particular antenna that is necessary for T-Mobile's LTE service. His concerns are partially unfounded, as T-Mobile is supporting LTE over several bands and the lack of band 12 will only be noticed in areas where LTE is only available using bands 2/12 (one for uplink, one for downlink). In fact, I'm on T-Mobile LTE right now.

    Additionally, T-Mobile is slowly converting their existing bands to be more in line with the rest of the industry's bands, so the need for band 12 will be obsolete soon. Forward thinking by most manufacturers are driving them to omit band 12 hardware, as it's unnecessary cost (primarily manufacturing infrastructure & hardware design costs which most people don't consider) to include and probably won't be used in a few years. Why have two different assembly lines (2x the infrastructure cost) where one makes X units/hour and the other some small percentage of X/hour when you can have both lines making the same thing for a total of 2X /hour for 2x the infrastructure cost, or X units/hour for 1x the infrastructure cost.

    hope that helped.

    While your reply is thorough your explanation of it being due to cost is somewhat inaccurate. Band 12 is a subset of frequencies near 700mhz most phones support band 17 which is nearly the same as band 12 but it eliminates the lower portion of the band 12 spectrum. In turn means most phones already have the needed hardware for band 12 but manufacturers have chosen not to enable it.

    it looks like this could be fixed with a simple patch to the NV files to enable them. I did notice that it was showing Verizon (Forbidden) on my Network Providers page but I did not probe further. I may dive into it once the signal is active in Denver.

    I'm in the Minneapolis market where band 12 has already been deployed. I will be doing some testing but have not had time to do the NV edits yet.

    It seems that the LTE Discovery app was not reporting the bands properly.

    The LTE Discovery app was not correctly identifying the band. Much ado about nothing. Sorry guys.
