Band 12 LTE spotted in a few markets, 20+20 Wideband LTE in Los Angeles


Following updates battery-improving updates for the Galaxy S6 and S6 edge as well as Android 5.1 for the HTC One M9, it looks like we’ve hit the good news trifecta today with some new band 12 sightings.

Several users on reddit have spotted band 12 LTE in Glendale/Los Angeles, New York City, and Indianapolis. More specifically, the NYC site appears to be set up at Longfellow Ave. in the Bronx, and reddit user milan03 says that more cell sites should go live next week. Meanwhile, Team Magenta members in Indianapolis can find band 12 in Southport.


Separately, T-Mo customers in LA and Burbank appear to be seeing 20+20 Wideband LTE service.


T-Mobile CEO John Legere teased back in late May that NYC would soon see band 12 LTE, so it’s nice to see that service finally live. If you’re in NYC or one of the other lucky markets that’s now seeing band 12 LTE, you should start to get better service indoors. If you are indeed able to get onto this fresh band 12 LTE, be sure to let us know what your experience has been like so far!

    Band 12 is live in Kalamazoo Michigan and Portage Michigan. The download speeds are around 4 to 8 and the upload speeds are around 1 to 3. Upload speeds seem a little flaky at the moment. I’m using the LG G4.

    • Justin Smith

      Screenshots? We can’t verify without them!

      • Luther

        I don’t need it verified. You and everyone else don’t have to beleive me. I’m simply sharing what I am seeing in my neck of the woods.

          That’s not how it works.

          If you make a claim and someone challenges it, you have to provide proof or the claim is false.

        • Luther

          Then I guess it’s false. I don’t HAVE to do anything. This is why I don’t like leaving comments. The comment section on almost every website these days turns into a big pissing war. You don’t HAVE to beleive me. I could care less either way.

        • Fabian Cortez

          If someone asks you for proof, it shouldn’t be that hard to prove your claim, if true.

          If you’re solely basing your Band 12 discovery off of speed tests then I’d be inclinded to not believe you.

        • Luther

          LTE Discovery app is where I’m getting my info from. I’m at work right now and don’t pick up band 12 here. If I’m thinking about it the next time I pick it up I’ll post a screenshot. This way I don’t have to hear it anymore. I mean really people, if you don’t live in or travel to the areas I mentioned above then why does it matter so much to you. For those that do live or travel to the areas I mentioned above you will notice better signal and coverage. So basically this whole post should only concern a select few.

        • Fabian Cortez

          Just as I suspected.

          LTE Discovery, SignalCheck [Pro], and CellMapped are inaccurate when it comes to discovering Band 12.

          It’s best to confirm Band 12 using the phone’s engineering screen as posted in the article.

          EDIT: There are other reason why accurate data is necessary so please attempt to get a screenshot from your engineering screen.

        • Luther

          I’m done with this. I’m happy with what I have seen and that’s all that matters to me. For crying out loud. I have better things to do with my life then this.

        • Fabian Cortez

          It is a fact that those apps are inaccurate when it comes to discovering Band 12. There are plenty of false positives.

          So instead of having your meltdown, why not learn to properly check if you have Band 12 instead?

        • Mike Thaler

          I’ll be getting a G4 in the next 3 days. How do I get an “engineering Screen”?

        • Fabian Cortez


        • Justin Smith

          TmoNews is usually a friendly comment section. I have to say that people such as yourself take things and make them bad sadly. I just wanted to have proof so it could be added to the 700Mhz map

        • YABD

          I trust you because I go to Angola, Indiana 3 days a week which is next to Michigan and I have the same speeds.

        • Fabian Cortez

          Really? And there were weapons of mass destruction in Iraq and the moon is made of cheese.

        • YABD

          I trust you too.

        • DStudio

          Well, that’s one good example and one very poor one. The cheese moon idea is ridiculous to start with. The WMD is quite plausible, and not finding them is no proof they never existed – especially given the time delay before they were able to look for them. I heard from an inside source they may have been moved. But even if they weren’t, you must distinguish pure fantasy from possible/plausible reality.

          Let’s review:

          Green Cheese Moon – fantasy
          WMDs were in Iraq – possible, at least

          Moon landings were all faked by US, USSR/Russia, and everyone who came back – fantasy

          Luther/Josh found band 12 in Kalamazoo – probable/yes

    Thank goodness for NYC. I was there a month ago and it wasn’t as good as South Florida coverage.

  • shamatuu

    So what about in milpitas ?

  • Arturo B

    Finally NYC has live band 12, now crossing my fingers for the next iPhone 6s to support that band.

  • dontsh00tmesanta

    Madera, CA too

  • Jason Caprio

    This is awesome! Currently using a Note 3 and I am looking forward to the Galaxy Note 5 release to take advantage of Band 12. I wonder if Band 4 20×20 LTE will use carrier aggregation with Band 12 5×5 to make 25×25?! Maybe even throw Band 2 into the mix for 3-way aggregation!!!!!!

    • Nick

      That would be frickin amazing

    • Fabian Cortez

      25×20 MHz.

  • Justin Smith

    Finally T-MoNews is acknowledging Reddit and its users as where most of the news comes from! It’s always great to see improvements, especially when it comes to band 12 upgrades.

  • Band 12 Love 4 FL?

    So where’s the action in Florida? I work at one of the largest employers in the Tampa Bay area and in my office in Tampa my Note 4 STILL drops to Edge with 1 bar when I’m next to a window… and Im lucky to be able to text without logging into WiFi.

    • Fabian Cortez

      Band 12 has showed up in Tampa in March 2015 and has been official for a while now.

      • randian

        Is Miami/Fort Lauderdale/Palm Beach covered?

        • Fabian Cortez


        • sushimane

          i was in south beach/fort lauderdale last September with a nexus 5 i maxed out at 50 something. pretty sweet.

    • GinaDee

      Probably as good as it’s going to get. T-Mobile already “upgraded,” your area.

      Verizon and AT&T have been using low band spectrum in most markets for years now and even they still have areas indoors where service is not optimal. Realistically I don’t expect T-Mobile to be any better and they have a handicap already several years in the making.

      You are probably better off with AT&T.

      • TMOTECH

        Go away


      Tampa has band 12. You won’t see it unless you have practically no signal from Band 4. Unless of course you have a phone with engineering mode and can lock onto it. T-Mobile is not done in Tampa though. And once we turn on Carrier Aggregation you will see a huge difference.

      • Cam Fas

        What’s the carrier aggragation timeframe? We need it now

    • vinnyjr

      Are you using a phone that has the Band 12 radio? If not could be your issue.

  • PHL

    Still 15×15 where I work in South LA/Torrance area. Will check my home in Riverside CO tomorrow, where I live about 500 yards from a TMO tower.

    Off-topic, but is there a way to report poor network performace to T-Mobile. I consistently get speeds below 1 mbps, even though I have 3-4 bars of LTE signal. I understand congestion, but this is really bad. Often, SpeedTest shows DL speeds 50-100 kbps. UL is a little better at 1-3 mbps.

    T-Mobile’s had 20+20 in the Panama City, FL market now for probably 6+ months, I’ve just forgotten to send it in. I don’t think it’s ever been reported.

  • Kenneth Warner

    I was in pismo beach Ca and had like 38 down and 20 up I was like omg I’m in heaven

  • Hector

    Been having band 12 for a couple of months now.. I live in Fresno Ca… However signal indoor was great but for some odd reason speeds where not so great

    • DStudio

      That’s because T-Mobile has nowhere near as much bandwidth on band 12, as mentioned below. But the key is having something usable inside. Even the other carriers are (generally) having to resort to the higher frequency bands for their fastest speeds.

      • dtam

        exactly. tmobile only has 5+5 Mhz of band 12 whereas they have 15+15 or 20+20 Mhz of band 2 or 4

  • DStudio

    In Southern California T-Mobile, Sprint, and Verizon have all been making significant boosts to their speeds, and in many spots any one (or even all) of them can provide 40+ Mbps down and 10+ Mbps up on a regular basis (with the right hotspot or phone).

    It’s really nice to see the progress they’ve made.

  • nycplayboy78

    How do we contact Alex via email to pass on to him news stories? I am not on Twitter. Is there a TMONews FaceBook page or an email address we can reach out to him?

    • PHD

      There is a button at the top of every page that says “Submit News” You can’t miss it if you are paying attention.

    • SirStephenH

      There’s a large link at the top of the page to a form. The form didn’t work for me lately but the page lists Alex’s email so you can submit to that.

  • steveb944

    Meanwhile, the last couple days my LTE is gone in the Miami area.

  • Mike Palomba

    I can’t wait to get the iPhone 6s so I’ll be able to access band 12 in NYC.

    • vinnyjr

      That is if the new iPhone picks up Band 12. The iPhone 6 and 6+ should have Band 12, they had time to implement that radio and didn’t. I bet they would have sold many more iPhones on T-Mobile if they had Band 12.

      • eanfoso

        the general iphone owner is only concerned about the apple logo, they don’t have time to check the hardware side of things.

      • You really think so? How many iPhone buyers (or even phone buyers in general) know what Band 12 is?

  • Geoffrey

    Not sure if this was already stated but Band 12 is online in Philadelphia today.

  • Jay

    Troy, Michigan has Band 12 signals captured on Galaxy Note 4 as well. Would like to upload the pictures, however no clue as to how should I do that. Screens captured are on LTE discovery app and also on Service Mode. Please guide me how to upload them.

  • I am debating getting a Lumia 640 or waiting until the 950 XL comes out.

  • Jimmy James

    The highest I’ve ever gotten on band 12 was 15Mbps. You can also tell when browsing that page loading is slower, as Band 12 does not have the same bandwidth as 4. I am in a dead zone in my metro neighborhood. It shows I should have a strong signal on the map but I don’t. It was working fine, then 6-8 months ago something changed. My band 4 will always drop off and default to 12, then go back to 4 sometimes, then back to 12 most of the time. Sometimes even 3G. Finally after a few calls of complaining, they were supposedly checking the tower (yeah right), after even buying a new phone, they finally gave me a 4G LTE repeater box, which keeps me locked onto Band 4. For that alone, T-Mobile has the best customer service.

    • So how does the phone decide between bands? Does it prefer 4 when available?

      • Jimmy James

        Yes. It keeps trying to connect to 4, but in my situation it could not hold it’s connection to 4, so it kept switching to 12 frequently. Most of the time it would only connect to 12. I use the program LTE Discovery to see which band it is on.

  • erichola

    SGV got 20 Mhz band 4 LTE today.

  • Joshua R

    My Band 12 works great in San Antonio & Austin Texas… I love my Nexus 6… I can get LTE everywhere!

  • J-Hop2o6

    Band 12 in Seattle NOW! I always had a weak Band 4 (AWS) and Band 2 (PCS) LTE signal at my work (Brick building). Noticed I had a nice signal inside when I normally had a very bad signal. My SignalCheck Pro icon in my notification bar said “LTE12” and I was confused and thought that was a error, but my signal bar kept being consistent. Then I check Samsung’s servicemode, and it confirmed I WAS on Band 12 @ 5MHz. T-Mobile is on a roll! Thank you!

    Speeds aren’t great right now, but I already expected that @ 5MHz (Band12 is for signal distance and building penetration for LTE mainly).

    Anyone else in or around Seattle noticing Band12 LTE?

    • SirStephenH

      I’ve seen reports of it popping up online but unfortunately I live on the other side of the Sound so I haven’t noticed any B12 love yet. I did forward one of the reports of B12 on to Alex before this article came out but for some reason he chose not to add it.

  • PHL

    Just checked my phone. 20 Mhz Band 4 at my office in Gardena, CA

    • PHL

      20 mhz in SW Riverside county this morning.

  • Hondaking96

    Band 12 all over Miami

  • I can’t wait for Band 12 in Downtown Los Angeles. I’m already getting great coverage and good speeds. I’m excited to see if Band 12 fills in the gaps and makes it even faster. What’s the delay??

  • Finally getting Band 12 in LA!
