T-Mobile band 12 LTE spotted in California, Wisconsin, Delaware, and other locales


T-Mobile recently said that its Extended Range LTE — aka 700MHz, aka band 12— coverage now reaches more than 340 markets. Here are a few cities where it’s been spotted recently, as well as some other notable T-Mobile network sightings:

San Francisco, Calif., in the Mission District (carrier aggregation with bands 4 and 12)


Alameda, Calif. (band 12)


Rehoboth Beach, Del. (band 12)


Milton, Del. (band 12)


Greenwood, Del. (band 12)


Queen Anne, Md. (band 12)


Tysons, Va. (band 12)


Central Wisconsin (band 12, between towns of Thorp and Owen)



Rockford, Ill. (20×20)


Houston (band 2)


Thanks, Willie, Ivory, Brian, and John!

    Yet again Vegas left in the dust….. Didn’t they announce band 12 in September of 2015 for Vegas and I’m still twiddling my thumb we need it at the airport bad.

    • VN

      Maybe you people need to repent first. You never know how these things works.

    • Yeahs what’s up with Vegas? And if they could get the LA to Vegas route solid with LTE that’d be great too. ;)

    • Magenta Man

      Vegas licensing for 700mhz band 12 was was just purchased in January. The planning and development stage is almost complete. Literally as we speak the sites in Vegas are getting approved and deployment will begin shortly.

      • Dave

        So we are probably looking at about 6 month if not longer to get band 12 deployed.

  • VN

    Thanks for also reporting about Carrier Aggregation and Band 2 sightings. I would prefer more B2 and B4 network improvements in my area, and of course CA, than B12.

  • Wow, 10 MHz of band 12 in CA???

    • Justin Smith

      That is impossible currently.

      • It is possible if T-Mobile has the license or an agreement to use block B of band 12 alongside its holdings of block A. As of February, it’s possible in parts of North Dakota and of South Texas. After the many license purchase deals and agreements in band 12 between T-Mobile and other carriers or spectrum squatters, it’s not only possible, but bound to become more common.

        • Justin Smith

          … My comment was in context of the original comment. So I am correct, it is impossible in California currently.

  • Sushimane

    Is there only 2 band arrgreation for tmobile at the moment

    • Bradley Karas

      Yep and only for band 4 and 12 in those areas…haven’t seen band 2 and 4 or band 2 and 12 yet

      • Band 2 and 12 is T-Mobile’s primary carrier aggregation. Band 4 and 12 is for major cities, such as Los Angeles.

        • 9to5Slavery

          What about Saint Louis?

        • STL would likely have the latter.

        • 9to5Slavery

          When you say that, what does that mean? Can you specify, this area/location feels left out many times.

        • Ok. I take back what I said then. Found out that US Cellular owns the STL licenses. So, little to no chance of having T-Mobile Band 12 there.

        • 9to5Slavery

          No no no, i mean the aggregation of 2 & 4.

        • STL might have 2 & 4 aggregation by the end of June, I believe. I don’t know the exact timeline on that.

        • 9to5Slavery

          Can you specify source?

        • I have seen some Reddit threads, but that’s about it at this juncture. Most Redditors are focused on Band 12.

  • Jealous. I don’t think we have any Band 2 in LA? Or any carrier aggregation, or MIMO ether for that matter.

    • Justin Smith

      In LA carrier aggregation is enabled, and all LTE has MIMO. The only difference is most of your MIMO is 2×2, but they are starting to deploy Ericcson’s new AIR32 antennas which support 4x4MIMO in LA.

      • Omar Boyer

        im in los angeles and its pretty sloow on my s7 edge which supports all their lte bands , east la,montebello ,pico rivera 1-3 mbps they need to fix it spoon .. sometimes speeds get as low as 1

      • 2×2 ain’t bad! I’ve not seen 4/12 CA ever. Source?

        • Justin Smith

          Reddit posts about every ten minutes.

  • Javier Salinas

    Does anybody know why mine field test app shows unknown for download /upload bandwidth and frequency band indicator says 777912647

    • maximus1901

      Bc you’re using the iPhone 6S

  • Walt

    How do you get the iphone to show upload/download bandwidth indicators. Ie 20mhz

    • Bradley Karas

      *3001#12345#* then hit call

      • VN


      • moonoverparma

        I still can’t get mine to display the MHz

  • mreveryphone

    I’ve been working in central Wisconsin for around 8-9 months where T-Mobile is non existent… To see band 12 reach that far into central Wisconsin was an eye opener to say the least. Seems like T-Mobile is concentrating on where they are not, establish a presence in those areas and use that new money to strengthen the already strong areas… Or I’m just wishful thinking… Either way it’s a win win for everyone!

    • Bradley Karas

      That’s huge considering besides US cell there really isn’t a presence in that area at all

      • MyBetterUserName

        HWY 29 is north of USCC’s coverage area. That is AT&T land.

        • mreveryphone

          Yep… Everyone I work with that lives there has att or sprint… And neither are happy. Soon enough T-Mobile will be there stealing their customers!

      • mreveryphone

        Very huge… It’s only a matter of time…

  • Bradley Karas

    Talked to my T mobile rep yesterday and in Tampa they are prepping for 4×4 MIMO and 3 band CA they have been upgrading towers between Tampa and Orlando since January. They are also very close to launching multi phone SIM where two phones can share the same number. T-mobile is going after Verizon in a big way

    • disqus_DFnvXJ7c9h

      And it’s working! I would have never considered Tmobile 2 years ago. But since their improvements I jumped ship back in Oct. 2015 and have had almost the same coverage. Better in some parts, worse in others but nothing that would make me regret my decision. In fact I couldn’t be happier! Hold onto your plan tight as once they have coverage similar to ATT and VZW plan prices will definitely increase.

      • More likely is that T-Mobile will add more plans and increase the price of their unlimited plan.

  • StevenM

    We need it. Data has become very slow in many parts of town with speeds less than 1mbps becoming common during peak hours.

    • Anonymouse

      true. my usual spot in Kingwood where i test speeds has slowed down. i used to get as i fast as 80 mbps now i can’t even get half of it. And I’m testing on the same spot and the same time.

  • Sean

    How is this news? Half these places have had Band 12 for a long while now.

    • carl

      That’s what I was thinking. What if some are repeats or even fakes?

  • David

    Nexus 5x user here, how do I see the band frequency information?
    Do I need to download a special app to see it?

    • Stefan Naumowicz

      LTE discovery

  • dontsh00tmesanta

    B12 is already overloaded in sf

  • Jay Holm

    Sure would like to have some Tri-Band Carrier Aggregation here in Houston please, like now. No such thing as too much speed!

  • Walt

    What CA does t mobile currently use? Band 4 and 12 only?

    • Calgrav24

      In the major cities they use B4/B12 CA and in some cities and rural areas they use B2/B12 CA.
      Soon in major areas we should start to see B2/B4/B12 CA together which should improve speeds.

  • Patrick McLaughlin

    Does the iPhone 6S use Carrier Aggregation?

    • Yes. It uses Band 2 + 12 (mainly) and 4 + 12 aggregation.

      However, you can disable aggregation on the IPhone 6s and 6s plus.

      • Walt

        How do you disable it?

        • *3001#12345#* And then press call. That’s for the IPhones.

        • keasycase

          How do you disable it from there

        • Use the field test from there, I suppose. I’ve never owned an IPhone.

      • 9to5Slavery

        Why would you want to ? Can you explain?

        • People who have Lumias and IPhones want to disable carrier aggregation occasionally to see if T-Mobile added new LTE spectrum. That’s what you see on those screenshots.

        • 9to5Slavery

          I see. Thanks

      • Sean

        You cannot disable it. You can only see network information.

  • Al

    What about Chicago???? Band 12 was slated to come here for over a year!

    • I don’t know who told you that. Chicago has never been in any Band 12 discussion that I’ve followed. I’ve been following that discussion since Day One.

    • You’re out of luck. Band 12 is licensed to a spectrum squatter which never had the intention to use it, just to sit on it waiting for a profitable offer. That’s the FCC for you, reaping profits at the expense of the taxpayer.

      • guest

        So what, if you want to be “spectrum squatter”? It’s your money, your investment. What are you, a liberal?

        • On the contrary, that’s why i loathe state sponsored “investments “, or crony capitalism.

        • guest

          What would be your utopia then, no states? just anarchy?

        • My utopia would be the Internet without trolls like you.

        • guest

          Most people push their own utopia, knowingly or unknowingly, and of course some utopias are more realistic than others, easy to understand. What I don’t understand is “crony capitalism”.

        • disqus_DFnvXJ7c9h

          Because spectrum is a public commodity. It’s a public good sold in exchange for producing a product for the public. It’s not a stock or private commodity. Same reason cable companies were given exclusivity by region in return for building out the expensive network. But that’s also why they can be regulated. Unfortunately the timeline given to use the spectrum and ability to resell or license it makes it possible to squat. That should change

        • guest

          I agree, if the “squatters” are not doing anything outside the “rules of the game” then it’s okay to squat. But if people want change to happen then the government should adjust the “rules of the game”.

  • Hiro

    While I can’t confirm it’s band 12, it appears that stronger LTE coverage/signal appearing on I-75 in SW Florida compared to even a month ago. Anyone else down in this area notice that as well? Fort Myers-Naples stretch.

  • 9to5Slavery

    Status updates of beautiful St. Louis / St Louis / Saint Louis Missouri carrier aggregation ?

  • Got to see Band 12 in action over the weekend heading to Ocean City, MD from Harrisburg, PA. Had it along Route 50 in some areas. Saw it again on the way home through Dewey, Rehoboth, etc. Pulled over 20 down on Speed tests. My girl’s phone does not have Band 12 and we got to compare. Worked great!

  • J.v

    Somewhat new is the 20mhz(happened just a day ago) band 4 in Tyler tx(eastern TX). They have a select few sites with band 12, and a few outlier sites with band 2. Both at 5mhz. Have screen shots if you would like. Also got Carrier Aggregation on band 4/band 12 on those select sites with both active.

  • Jim M

    When are they going to bite the bullet and just buy the Chicago spectrum, this is getting ridiculous.

    • John Legere

      Today. They announced it today, 5/25/16. It will officially close Q4’16 and it cost them $420M.
