T-Mobile band 12 sightings in Georgia, Massachusetts, Washington, and more


T-Mobile has made a point to let us know that the iPhone 6s and iPhone 6s Plus include support for its band 12 LTE, making them the first iPhone models to do so. At the same time that Apple is launching its new iPhone hardware, T-Mobile continues to work hard to roll out the band 12 LTE that the new iPhones support, hitting 170 markets with band 12 with the goal of surpassing 350 in the next three months. Here are a few of the recent additions that’ll help T-Mo reach that goal:

Northeast Atlanta, Ga.


Canton, Mass.


Puyallup, Wash.


Kansas City, Kan.


When T-Mobile announced its Lifetime Coverage Guarantee last week, it also shared a map that shows what it expects its coverage to look like when 2015 is all over. Check it:



Thanks, Jason, Mike, Wade, and R3V0LUT10N!

    No band12 in IL OR CHICAGO YET!!!! No love

    • Jb15bq

      They don’t own the license to use band 12 there.

      • Uri

        So it’s pointless to buy a iPhone 6s with band12 in IL OR CHICAGO?

        • Jb15bq

          There is some hope. AT&T has to sale the band 12 license for Chicago they picked up from purchasing Cricket. It was part of the terms of the approval of the feds for them to purchase Cricket.

        • But, they DON’T have to sell it to T-Mobile. AT&T can sell it to the hometown carrier, US Cellular.

        • Tom@L

          yes pointless for Chicago or Phoenix residents for now.

        • PFeezzy

          Not pointless for Phoenix. Phoenix has two separate 10 MHz LTE carriers in band 4. The 6s has carrier aggregation that can connect to both those 10 MHz at the same time making it almost like a 20 MHz contiguous band.

        • Tom@L

          check the 700hmz map. 700mhz is still protected for TV channel use. It will be some time before that is made available.

        • PFeezzy

          I’m not talking about band 12 700 MHz. I’m talking about band 4 AWS and carrier aggregation in band 4 ONLY. T-Mobile owns 20 MHz of AWS in Phoenix but it is not contiguous. It’s broken in two 10 MHz blocks. Carrier aggregation can pair those two blocks for the downlink making it almost like a 20 MHz downlink. Bottom line, If someone wants to take advantage of carrier aggregation in Phoenix on an iPhone, then they are going to NEED a 6s.

        • Tom@L

          carrier aggregation works on iphone 6 also upto 20 mhz …. you dont need to buy a 6s for that.

        • PFeezzy

          Yes. It does, however, the 6 does not support intraband band carrier aggregation on band 4 like the 6s. The 6 only supports interband. So you do need a 6s for that.

  • Raymond Guerrero Jr

    Still waiting for them to work out the band 12 situation here in Phoenix!

  • mingkee

    No trace of B12 in Grand Central and Fort Hamilton.

  • msohail

    Bring it to San Francisco !!

  • voLTE

    voLTE for BYOD devices should be a priority!

  • Fabian Cortez

    Those LTE Discovery Band 12 sightings should not be relied on.

  • YABD

    A question. Band 12 means where tmobile didn’t have coverage now will have? And somebody know if Indiana have that band since I saw the map and there is a big red area. Thank you.

    • SirStephenH

      They’re putting band 12 on existing towers. Band 12 will only allow for a longer coverage range and better in-building coverage.

  • SirStephenH

    At least the Dakotas will have good coverage…

  • David

    Do we have a timeline for band 12 in SF bay area?

    • JaswinderSinghJammu

      Someone said a while ago they saw band 12 pop up near Lincoln ave San Jose but personally I have never picked any band 12 at all

  • Sushimane

    Yes lowell,ma got band 12

    • williejackbrainer

      I noticed that too last week.

      • Sushimane

        Where do you live? The band 12 in my area goes off and on. I’m currently on band 4 lte.

  • substance

    Monterey, Santa Cruz, Carmel and Salinas would definitely benefit from band 12 coverage! as would the rest of the central coast and bay area.

    • JaswinderSinghJammu

      I am hoping south bay launch should extend to Santa Cruz, Monterey and Hollister area.

  • john

    educate me on these bands! what is band 12? I live in ORD. When i go to suburbs of detroit or Wisconsin, there is no signal at all. I care about better coverage! thanks

    • It basically means that in areas with towers upgraded with band 12, they’ll be able to reach further away areas. Band 12 is also better at building penetration, so better coverage indoors.

    • GersonT1000

      This is the way I understand it, and trying to keep it as simple as possible:
      Mobile phones work by tuning to the frequency of the operator antennas. The government sells chunks of frequency to the operators so that they can use it (it has to separate the chunks of frequency into different levels so that it can authorize the different chunks for different types of use so that there is no interference). Each chunk is a band. Band 12 is the one around 700MHz. This is one of the lowest frequencies available to mobile operators (it might be the lowest, but I’m not sure). The lower the frequency, the further the signal reaches and the easier it penetrates through walls, so you have better reception indoors and a stronger signal away from the tower. T-Mobile is in the process of modifying their antennas so that they emit these bands of frequency (band 12, of 700MHz), and your phone needs to have the radio antenna which can pick up this signal. Different phones have the ability to pick up different bands based on their antennas. Thus, the newer phones have band 12 support so if you are in an area where it is available, your phone will have even more bands that it can pick up on, and you will have a better chance of having a signal and having a stronger signal.

  • walt

    In that picture what are those thick cell antennas used for? i’m assuming LTE??? i’ve noticed those on a select few towers (not many) along with longer antennas on towers that around about double the size of the regular antennas that are already on the tower. any guess’s?

  • eanfoso

    Dang! Montana will finally have native coverage!

    • jay_max

      Western Montana, yes. But the other 2/3 of the state will likely be roaming well into 2016.

      • EndlessIke

        the fun part of montana

  • Cam Fas

    Time to buy some band 12 spectrum from one of the two holders in southern Nevada we would like band 12 it would compliment the 20+20 wide band we have in Las Vegas. Carrier aggregation on top of that heak but 10+10 in Vegas other then the 5+5 so we can have 30+30 just because we want the latest and greatest lol

  • Matt

    I’m a magenta fanboy but I think the map graphic shown is a bit optimistic.

    • Cam Fas

      Tell me about it the part that needs to be shown are the partner areas that’s when the lte conversion looks depressing when you see the partners a third of the map is roaming on edge

  • darwin

    I’m connected to band 12 here in Miami Gardens, FL 3 miles west of Sun Life Stadium…

  • Joen

    How do you check if you have band 12 coverage on iphone?

    • darwin

      You dont, it’s not supported, unless u have ur hands on a 6s/6s plus

  • J.J.

    Loving the coverage but recently got zinged with no penetration in a building in ne Indiana(Fort Wayne) waiting on that band 12 but it looks like there are no plans/spectrum in my area. Bummed!

    • Mercedes

      Yeah, unfortunately T-Mobile doesn’t have the license in that region for Band 12.

      • J.J.

        Sucks cause other that occasional penetration issues they have been great

  • walt

    does t-mobile have more cell towers than the other big 3? if so how many cell sites do they own/operate?

    • ⓜ@®!ⓞ G@®CI@ ™

      I know they have more than 50,000 last time i checked. Should be more now

      • taron19119

        T-mobile is useing Verizon towers to build more coverage

        • EndlessIke

          Verizon sold most of its Towers. T-Mobile is using towers owned by the big cell tower companies, just like the other carriers.

        • eanfoso

          …. you do realise Verizon uses different technology than t-mobile, thus making it incompatible to interoperate. I.E. 700 mhz frequency is on band 17 block c, t mobile uses band 12, and 700 mhz is the most abundant type of LTE Verizon uses.

        • I don’t think you understand what he is saying. There are companies out there that own the towers in strategic spots. Any carrier can put their antennae on it. These towers can hold equipment from ATT, VZ and Tmobile with room to spare.

        • VZ uses Band 13 LTE as their primary LTE network band. It’s referred to as the 750, the Upper C or the Upper Cluck Cluck Cluck (as I call it).

          And that’s the kind of insanity Mexico is getting rid of by measuring l mandating carriers to adopt Band 44 LTE as it’s primarily 700 network operations. The FCC should have required the carriers in the US to do the same and require broadcasters to vacate Channel 51 in the process.

        • taron19119

          Yeah but t-mobile verizon at&t and sprint sold there towers to a tower company and are leasing them back and the tower companies is lease space on all the towers too any carrier that wants to use the extra space and T Mobile leasing the extra space everything will verizon tower to match There coverage

  • alphanu22

    well well wont you look it that. just fired up LTE Discover here at me house in Lake Stevens, WA and boom Band 12 http://imgur.com/9GUlk9k

  • A Guy

    I live in Wichita and recently drove to Kansas City area and outside of some small patches I had 4G the whole way. Ad in my house I was on edge for the longest. I still have problems connecting even though it does read 4G which is a great improvement around here. I just ordered the new iPhone (im a fanboy) so I am looking forward to band 12

  • Kidding Me?

    So is this map native T-Mobile coverage or roaming coverage with native coverage included? I live in Michigan and I can tell you that parts of Wyoming, MI has poor coverage in homes, parts of Cedar Springs has no coverage, Greenville still roams on AT&T, and as soon as you hit past the Pierson exit on US-131, you are roaming all the way northward into the UP.

    • Trevnerdio

      Definitely with roaming. But that’s okay, as long as it’s low-ping 3G roaming, it doesn’t even matter to me if it’s slow. As long as I can get by with it on data, make phone calls, and text.

      • EndlessIke

        It would matter if you’re capped at 50 MB on the domestic roaming. I was recently in Missoula, MT and ate through 50MBs in about 6 hours of not particularly heavy usage.

        • John Wentworth

          Yeah the domestic roaming caps are very tiny.
          I’m glad I don’t have any roaming areas around where I live for hundreds of miles.
          Kind of insane that you get better performance roaming in Canada and Mexico than you do in the states. Speaks to the problems the US has with roaming rates.

        • Tmodev

          True! ^^^

    • Fabian Cortez

      “Coverage.” So yes, roaming.

      That’s their EOY 2015 map + CCA roaming.

  • Chad Dalton

    i dont know if i’ll believe that map just yet!

    • Fabian Cortez

      That map is their EOY 2015 map + the CCA coverage map.

      Google the CCA coverage map.

      • Aaron Davis

        It also includes all areas covered by roaming through at&t apparently.

        There are no t-mobile towers in South Dakota, and the CCA map shows no coverage for most of the state.

        • Fabian Cortez

          T-Mobile is actually expanding in the Dakotas natively.

  • ArchangelRenzoku

    Where do people report band 12 sightings to?

    • williejackbrainer

      I share them with Alex.

  • Chad Dalton

    oh i just realized, that West Virginia is included, what a big surprise, you roam on ATT the whole time.

    • And parts of WV is in the National Radio Quiet Zone.

  • DominiMMIV

    Band 12 popping up here in the Mojave desert. In my office in Yucca Valley on Band 12 I have 3 bars consistently; prior had one bar of Band 4 with HSPA fallback. Battery life better. In my neighborhood a block away in the boulders used to completely lose coverage for a stretch now have 2 bars of band 12. They will have to actually put up some more towers though since T-Mobile had a habit of slapping panels on water storage tanks (not the cool tall ones found in the midwest) around here, not much height to work with. Panels 10 or 12 feet off the ground isn’t going to get you very good distance. AT&T and Verizon places their “distance” 700/850 towers on ridges and mountain tops here in the desert; T-Mobile with Band 2/4 didn’t have that option in most areas since most of the signal would be wasted just trying to get coverage to the highways. One of our main towers downtown is a flagpole they are currently working on, right now no room for the band 12 panels since it was designed for band 4. Interesting to see what they do with it.

    • The height of antennas is limited by the FCC. I doubt that T-Mobile would spend thousands of dollars to set up an antenna lower than it’s allowed.

  • Philip

    On Note 4, you do *#0011# and pop up the SeviceMode. No Band 12 in Macon, GA.

    • taron19119

      Do u have voice over LTE turned on

  • Philip

    How does Band 12 work? One tower cover the whole city? Or Band 12 need to be on each of the cell tower?

    • Ascertion

      B12 would need to be on additional sites. Specific panels broadcast it and it has better coverage than its B4 counterpart. It’s designed as a fallback band, so if you went outside of B4 coverage, B12 should kick in. It may not be on every site, but it’ll be on multiple sites.

    • Dominimmiv

      So far in my observation in my area they are adding the panels to the Band 4 towers but so far not on the Band 2 towers, which in the desert southwest is the primary band outside of the urban areas. Band 2 does propagate slightly farther so maybe that is the reason, Band 12 not a priority.

    • The B12 signal covers the area that would require 4 or so towers to cover with the B4 signal.

  • Love Tmobile, but common.. looking at that projected mad.. Do we really believe that this will actually happen in the next few months? Overly optimistic Mr Legere?

    • Chad Dalton

      Yea a little too optimistic! I dont believe this will happen for a minute…

    • Fabian Cortez

      That’s the coverage* you’ll receive as a T-Mobile subscriber.

      Understand what coverage means.

  • Bryck

    Does anybody know if the Motorola X pure supports Band 12, voice over LTE out the box? Thanks.

    • williejackbrainer

      No, it does not support Band 12.

    • Kyu Kim

      Yes it does. 4G LTE† (B1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 25, 26, 38, 41)

    • williejackbrainer

      Sorry I was wrong:


      GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)
      UMTS/HSPA+ (850, 900, 1700 (AWS),1900, 2100 MHz)
      CDMA (800, 850, 1900 MHz)
      4G LTE† (B1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 25, 26, 38, 41)

    • Bryck

      Thanks for the feedback. I guess I didn’t phrase my comment correctly. I know that the phone does support the band, but I heard that’s it’s disable until a future update. CAN ANYONE CONFERM IT? Thanks.

    • dtam

      not really confirmation, but moto disabled band 12 on their lower cost phones because getting VOLTE certification is supposedly a long process. since the moto x pure is higher end, you would think they would put in the effort to go through that process. speculation at this point though

      • bryck


  • John Galt

    Any sightings in Vermont or NH?

    • williejackbrainer

      I will know by this evening for NH, however last time I check in the city of Nashua it did not have 12 band.

      • Devin Klinger

        Would you be able to check the Durham, NH area where University of New Hampshire is?

  • Chad Dalton

    They need to push out this advanced messaging quick across the board…i’ve waited like three minutes for a text to send. NOT COOL!

    • williejackbrainer

      Curious what phone are you using Chad?

  • Rupesh

    Is there a place where one can see the list of cities that have band 12 activated? I think there are about 170 markets or so and according to John Legere, they will be @ 350 markets by the end of 2015. I reached out to T-mo on Twitter and the rep sent me the list of wideband LTE cities – Lol!!

    • Tom@L

      there is a 700mhz LTE map link at top of this website. Check that.

      • Rupesh

        I saw that but I don’t think that’s up to date. Do you know if it’s up to date?

        • Tom@L

          yes it is mostly uptodate. At least NYC looks updated.

        • taxandspend

          I think what’s not up to date is the number of band 12 towers displayed. If it is up to date for those areas that have had it for a while, this is bad news.

        • From Conyers, Ga. to near Talladega Superspeedway has verified Band 12 as well.

        • dtam

          it’s very up to date because the map is crowd sourced.

  • Chadd

    Can we please get band 12 in Lubbock, Tx?

  • No More BS

    That map is bull. Total bull. It shows roaming coverage as native coverage; zoom out on TMO website and you’ll see it’s the same thing.

    John Legere purposefully is purposefully misleading people by putting that map in an article titled “The new iPhone features radically expanded LTE coverage on T-Mobile. So we’re launching the first-ever Lifetime Coverage Guarantee!”

    Furthermore, TMO doesn’t have 700 licenses everywhere.


    • Joe

      Yeah I agree this is complete bull. The end of 2015 native coverage that they expect to reach is much less than this. Its pretty much all of their current coverage converted to LTE + expanding a bit on that and a bunch of new coverage in MI and TX and a few other states. Not low and behold all roaming becomes native.

      • Fabian Cortez

        Where was it ever stated that this map was native coverage?

        • Joe

          No where. The problem is the average customer will get deceived by this.

        • Fabian Cortez

          No where. The problem is the average customer will get deceived by this.

          Where’s the deception?

          I believe the map is as clear as Verizon’s map.

    • slybacon08

      T-Mobile did state in their report that they will cover an additional 600,000 square miles of the US (lower 48 I assume) with Extended LTE (band 12) by the end of the year. That is about an additional 19% of the land area of the US. They will get their biggest land gains in the Midwest and plain states.

    • A better map would have been a state-by-state coverage map for all states except Alaska and Hawaii.

    • Fabian Cortez

      Where was it ever stated that this map reflected native coverage?

      • Shawn

        They didn’t, All I see is a lot of reaching from naysayers, lol.

    • moonoverparma

      700 mhz brings new and more coverage

  • mreveryphone

    I’m working in Buffalo NY for a few weeks specifically the town of Lewiston and my coverage is in constant battle with Telus. Supposedly I’m right at the Canadian border… How do you locals deal with this? My phone is constantly on E..

    • Steve

      Lewiston isn’t great with any carrier except verizion AFAIK, hopefully that changes soon. I’m in North Tonawanda and service is pretty good, but in Niagara it seems a bit lacking and could definitely benefit from some more towers and B12.

  • emcdonald75

    I wonder how long it will take for T-Mobile to get roaming coverage activated in areas where they use rural carriers apart of the CCA Data Hub? I know C-Spire is one of them. I am afraid T-Mobile is waiting for C-Spire to get off their behind and implement VoLTE, which will take forever.

  • Over 183 days late and millions of dollars short. T-Mobile should have done the buyouts of squatters during the winter. They knew Apple was going to include Band 12 when the FCC ordered AT&T to start using Band 12 LTE for interoperability purposes.

    • emcdonald75

      The FCC should require bidders to have a plan of action in place to use spectrum or sell it after 3 years of purchase. Spectrum squatting should be outlawed.

  • Aaron Davis

    They are going to have a hard time covering North and South Dakota by the end of the year, considering that they have zero towers there and rely entirely on at&t for coverage.

    • KingCobra

      They already have LTE in some locations in the Dakotas.

  • Jayson Rodriguez

    Any word on Marysville, Wa having band 12?

    • alphanu22

      Not sure. Its nice having full bars all the time instead of bouncing between 2-3.
