Galaxy Note on T-Mobile USA?

I have T-Mobile and am in US.... I really am interested in the Galaxy note and am wondering if it is compatible with T-Mobile's 3G/"4G"/HSPA+ network? I don't know what these frequency bands mean for compatibility ...

It will only work on EDGE speeds. It doesn't have the AWS frequency (1700, 2100) required for their 3G/4G network.

That is exactly the response I was looking for in terms of technicality goes.
Thank you very much!

interestingly, many sites point to the India specific version of the phone being a "penta band" UMTS phone. and as far as i know penta band means T-Mo AWS support no?

Hello all,
This is interesting. Is there anyways to confirm that Indian version will have "Penta" band?
I read that Note will launch in India on 3nd November. May be will have to wait to find out.

I'm having doubts about that article, SGSII was 34k when it was released in India. Galaxy Note has to top that.

i can't find anything to suggest any carrier in India uses the 1700/2100 bands needed for T-Mo (US) 3G to work anyway. so it must be about something else.

There are many bands for UTMS, and t-mobile USA is the only one that uses 1700.
Odds are, even if it is pentaband, it still won't support 1700. It might, but it's unlikely.

what about the modem.bin from the galaxy s2 4g on the tmobile phone

I've been researching a bit and it seems that the files are about the same on these phones, so I don't see why it wouldn't work. That being said, I am in no way an expert, but I hope someone with more knowledge will chime in on this and give us a concrete answer.

phone frequency band is hardware specific. if the crystal is not tuned for the frequency, theres nothing you can do to make the phone to accept it

I guess I'll have to wait on the Galaxy Nexus then. Thanks for dropping that bit of knowledge on us.

I think that for now is the best idea

I still want this and thinking hard about pulling the trigger and just buying. Has anybody bought this on tmobiles network yet.

You will only get Edge speeds.
There is no need to confirm anything.
Hardware IS HARDWARE.
I would not consider getting T-Mobile's version of this for the sole fact that they'll mess it up by putting a pair of 1.8 ghz Qualcomm chip in there to support their 42mbps network.
It will be garbage once that happens.
At this point, you either accept it as being Edge only on T-Mobile's network, or you don't get it altogether.

Yeah I know it only works on edge but if a million iphone users are using it then it might be usable but I kinda want a real world test of the Internet and not just specs since that's the only thing that's holding me back

You could ditch T-Mob, or not worth it? I would leave my carrier for the Note.

I made an inquiry about the Note coming to T mobile directly to someone I know at Samsung. He did get back to me and said they have figured a way around the present problem with the present chip configuration and will come out with a version that will be 1700/2100 compatible. BUT, not soon (2012) and probably will be the next version of this type of 5" + smart phone ....... So it is edge only on TMO for now..............

By the time they actually get to bring something like that out the quad core chips will be out and other makers might bring out something similar hopefully.

Howdy all?
Currently I am using Dell Streak which actually was launched for AT&T. So I was only getting TMo's EDGE speed on my Streak. Which for me was not a big deal because I would only have to deal with slow speed while I am either away from home or work.
Some might find it silly, but what I did was, removed my data portion which was with the phone and actually got TMo's 4g hotspot. And I carried both, my Streak and hotspot always with me. Which for me works out alright.

Flash radios? No T-Mobile LTE

I have yet to get T-Mobile's lte on my unlocked HTC First. Does anyone know why? ( I have had 2 AT&T unlocked handsets running on lte in my area previously.)
Are there any different radios around I can flash? I am aware that the First and One Mini have nearly the same hardware. Could I try flashing a One Mini radio?
Thanks for the help.

I've also got my first with T-Mobile but all I can get is hspa+ yes we've got the necessary radios for LTE but the phone isn't programmed in a way that it can use them. You'll need a T-Mobile specific RUU for that. But our first is a at&t only handset so none is existent. Will something from the mini work? Maybe. But it's likely that you would end up with a brick. And I don't believe that a T-Mobile specific one exists. Go ahead an try it if you want tho and mess around with stuff but... Beware

I don't think lte is worth a possible paperweight. Finding a way to enable lte doesn't seem like too difficult of a task - not that I really know what I'm talking about.

Don't worry about it too much. Hspa+ speeds are great! I get an average of 8mbs down! But I'm in a completely refarmed area. Make sure to check on your device info whether you're getting hspa+ or umts as you might need a different APN. (Umts is 3g but shows up as 4g)

It's HSPA+. However, I live on the edge of the reframed area. In my city I get anywhere from .5 down, up to as high as 3MBs. On lte it was around 10-20 down.

Try these APN settings exactly. They got me an extra 2megs. And the refarming is extending rapidly. Not so long ago I got edge but now I've got great hspa+ everywhere. It will improve only who knows how long it'll take

Could someone test following build.prop settings on T-Mobile?
Don't forget to:
1. make backup of build.prop;
2. you must be s-off;
3. reboot after applying changes.

2. Change LTE features bits, exact number comes from HTC one mini; also there's specific number from T-Mobile HTC one, can't find it right now;
3. Enable additional LTE bands, that maybe supported by T-Mobile;
4 and 5. Specific at&t settings.

Alright my device didn't soft brick and still gets data! Sadly I'm in a 2g only area right now so it'll be a while until I can report back with any results. Hoping this improves something!

Had time to test it out now and there's no difference. Or at least not very noticeable so I returned to stock settings

I also didn't notice any difference. Thanks tho.

a little difference
i went from 10 mb up and 1 down to
15 mb up and 3 down so ill take it
now if some one can help me get 4g lte on this thing that would be great cause i cant figure it out

Could you please verify that your t-mobile sim works with LTE network in other t-mobile phones? Maybe problem in sim cart, cause LTE bands 2 and 4 that used by t-mobile are supported by this phone.

And what the reason of speed increase? Please share.

LTE-Advanced Carrier Aggregation

Since only AT&T variants of GS5 and M8 are the first devices capable of aggregating two LTE bands into a "fatter download pipe", has anyone actually seen faster download speeds? Chicago seems to be the first market with confirmed live Carrier Aggregation, so AT&T users should be able to see download peak rates in excess of 100Mbps when Band 17 and Band 2 are aggregated (10Mhz + 5Mhz). Other usual suspects should be dense urban markets like NYC, LA, SF, Detroit, Dallas, etc... Keep an eye open!
You can verify this by accessing ServiceMode:
1. dial *#197328640# and tap on "AS INFORMATION".
2. Check the first line which tells you if CA is enabled but not configured, Disabled, etc.
3. Post a Screenshot of that page.
And of course check the speedtest.net app, and monitor speeds

It'll take awhile before many of the Lte networks are updated to use this feature I assume. Mines enabled but in basic information it shows I'm only connected to the 10k 17 band while downloading from LTE.

Converting SM-N960D/Dual Sim Exynos to Full T mobile US

Hello Im pretty new with samsung devices. I like my device to be rooted so i bought the SM-N960D/Dual Sim Exynos (BRI,BRI,BRI,BRI)
I Noticed that my wides T mobile US snapdragon Note 9 signal is fantastic and also she gets LTE but with mine I don't get LTE and my signal is bad..

So it looks like the N960D is missing a bunch of bands that T-Mobile uses for LTE. It has bands 2 and 4 for sure, but it may or may not have band 12 (conflicting google info), and doesn't have band 66 or 71. This is the cause of your signal woes, and can't be fixed. It either has the bands, or it doesn't.

Based on most of the stuff I see online, the N960F / D does indeed have band 66 and 71.

http://phonedb.net/index.php?m=devi...e_9_td-lte_jp_sc-01l__sgh-n058__samsung_crown (which lists it as a snapdragon, so **** this site)
I also tried looking it up at the Samsung.cn and Samsung.jp sites, but not knowing where the phone originated from, I can't get an accurate idea of what it has or doesn't have.

So 2, 4 and 12, MAYBE 66, no 71? Yeah, 66 is huge for T-Mobile now. 71 is going to be a big deal towards the end of this year.

Since you say you like to be rooted, I'm guessing you've been rooted in the past? Do you miss anything major while rooted? What are the alternatives to secure folder and samsung features? How about banking apps and work e-mail, considering they use device management. Have you faced an issues with that?

I think you quoted the wrong person. Personally, since AdHell/SABS came out, I've lost all desire to root. Ad blocking and stock Android was my only motivation, but right now I'm digging the Samsung Experience UI.

U.S. Sony Xperia XZ3 & VoLTE on AT&T??

I was just wondering...........will Sony phones like the upcoming Xperia XZ3 (U.S. version, release date: 10/17/2018) be able to access ALL of AT&T's network radio bands without VoLTE certification? I know T-Mobile doesn't allow access to their 700 MHz spectrum (aka Band 12) without VoLTE certification, but does AT&T require the same thing? Or will users get FULL access, just no VoLTE?? Also, does AT&T actually require VoLTE certification??
Thank You!

I'm on T-mobile and VoLTE works fine. I inserted my coworker's AT&T sim and had the option to enable VoLTE. Unfortunately, I did not think to actually test it.

Hi.......thanks for responding!
Wait.........which exact Xperia phone do you have, and is it a U.S. version or int'l? I know it can't be the XZ3 as it (the U.S. version) doesn't get released on Amazon until next Wednesday.
Ok wait.........nevermind. Your signature logo tells me you have the 2017 XZ Premium. But is it the U.S. version or int'l??
Ok that is interesting about your phone showing the option to enable VoLTE with your co-worker's AT&T SIM card too. I'm sure if it actually showed up as an option that wasn't grayed out then it should definitely work too.
I wanted to know if a company like Sony didn't certify VoLTE with AT&T, would people who use their phones on AT&T's network get full access to ALL of AT&T's radio bands or no. If what you're saying is true, then perhaps they do? I don't know. lol

I have the XZ3. I bought it from Clove (UK), flashed with US firmware. The signature doesn't have the XZ3 in their database yet, so I can't update it. I'd love to test it for you again tomorrow when I get to work, however he's on vacation for 2 weeks.

Oh wow, cool!
So basically you're running a U.S. version then it seems, which is helpful.
Ha! Of course he is. Just my luck! lol
It's fine. I have T-Mobile, but thought that was a "dead issue" since Sony ONLY OFFICIALLY certified the XZ1 Compact with T-Mobile. When he gets back that would be cool if you could though as I have a friend who has AT&T and would like to know.
I guess I'm just shocked b/c this site doesn't have any information about really any recent Xperia flagships having VoLTE (and therefore access to Band 12/700 MHz). So you've tested your phone out using some kind of app to confirm that it can ACTUALLY access T-Mobile's Band 12 spectrum?? And I assume it stays on 4G LTE during calls too? (Please kindly answer both questions.)
Even if all this is true, what sux is the XZ3 (all versions) apparently DOESN'T have Band 71/600 MHz (under 4G LTE) spectrum programmed on it, regardless of version. And according to a recent update from T-Mobile, my area (Chicagoland region) is about to get that exact radio band by like the end of the year. Uggh.........f'ing Sony Mobile! lol

I used LTE Discovery to check what band I'm on and it's saying Band 4. And yes, it stays on LTE during calls. Refer to screenshots (attachments).

Yes, that's the app, LTE Discovery! I couldn't remember the name of it earlier. lol
Did they finally add Band 71/600 MHz to its list of bands it can detect??
So can I presume that 4G LTE & LTE+ are the exact same thing??
Ok but what about Band 12 though? That's the band that T-Mobile is supposed to require VoLTE certification for in order to access it. An LTE Discovery screenshot of that (must be during a call) would be great actually! I believe it can access Band 12 for data, but the thing I care about is having access to it for calls.
And ok your profile says you're from or in Manila?? I'm confused. lol I hope it's just from b/c if you're not in the U.S. then this info is kinda useless to me. lol
Thanks!!!!!!!

I'm not sure if they added Band 71, doesn't really say in the app. I guess you'll have to contact the developer for that. I have no knowledge of where Band 12 is deployed. I'm in the Philadelphia area right now. Signature is just where I'm from.

Oh ok. Not a big deal. I can just download it again and check it too. It would say in the Settings. When my area first got Band 12/700 MHz, I used the app to detect and notify me of every time it found a Band 12 signal. Shortly after, it began to pop up when I was like in elevators and parts of downtown Chicago, etc., which made me very happy. lol
You can check this map, though of course I think Band 12 will only get utilized when Bands 2 & 4 are not available. Philly? Ok great!! It appears you do have it too.
Well so far this is really great news!! I just can't understand why no one else is confirming this like on that site I linked earlier?? I would assume the U.S. version then will have it too since your firmware is U.S. for the XZ3.
Nice. I used to have a good friend who was Filipino too. Just lost touch over the years.
Thanks again so much!!

I checked and LTE Discovery does NOT currently offer Band 71 detection at this time. So I e-mailed the developer a few hours ago and requested it. Hopefully they add it soon so I can detect Band 71 when it hits my area in the next few months.
Thanks again for all your input! Much appreciated! I will check back with you in a couple weeks. In the mean time, I'm honestly CONSIDERING buying the U.S. XZ3 off Amazon (gets released next Wed) and testing it out myself. LOL I get Band 12 in my condo elevator and parking lot too sometimes, so I should be able to get a screenshot of the phone in Band 12 DURING a call via LTE Discovery when it's detected. But I doubt I'd keep it up cuz no Band 71. FML! lol Still, I'd wanna know for myself so that perhaps when the XZ4 comes out (or XZ3 Premium) if it will have Band 71 and VoLTE confirmed, I will most likely buy & keep it.

Yeah, the XZ3 is a really nice phone. Comparing it with my XZP, I believe it's a nice upgrade. Not a required upgrade, but still a nice one. You can also just wait for it to be available in Best Buy or something so you can try the phone out without buying it. If it comes out in Best Buy. I assume it will, since the XZ2P was.

I just got mine from clove as well - I'm on ATT and I don't see the option for VoLTE. Can you tell me where you found the US firmware and how to flash it? Thanks

Yeah, it won't show since you're still on UK firmware. Download the US firmware from Xperifirm, then use newflasher to flash it. Flashtool doesn't support the XZ3 yet.
After I used newflasher, things didn't feel right, so I just used the Xperia Companion to do a Software Repair. Basically the same thing as a full wipe, but it'll just download the latest firmware from the region you're currently on.

Yeah I would agree. Yes the XZP has a 4K screen, but not HDR (which of course the XZ2 P got both). The XZ3 having 2K + HDR is really something. Yeah plus it's 18:9 which I DEF prefer over 16:9, and yeah 845 processor.
Typically both Best Buy & Amazon get the newest Xperia phones. But for some reason, even at this point, it appears ONLY Amazon will carry the U.S. XZ3.
So...........even though it won't have Band 71/600 MHz when released, I decided to STILL go ahead and pre-order the U.S. XZ3 off Amazon (release date: next Wed) JUST to confirm for myself what you said and showed me................that with the U.S. firmware, the XZ3 WILL get VoLTE on T-Mobile and therefore will STAY in Band 12 & 4G LTE/LTE+ while on a call as well. If I can confirm this, that is HUGE. HUGGGGGGGGGGGGEEEE!!!! lol
I will of course keep you posted. In the elevator for my condo building b/c the reception is bad there, my phone always at one point switches to Band 12..........and THAT is when I'll strike. When my LTE Discovery app detects Band 12 being utilized, I will make a call right away, and if it stays in 4G LTE, then it's confirmed. If not, F U Sony Mobile!!!!!! F U and die! lol Then for XZ4 or XZ3 Premium, as long as they add Band 71/600 MHz (which my area will get activated on T-Mobile's network by about the end of this year), I'm 99.9% buying it. lol
Thanks again!!

Good luck RockStar2005, I am not optimistic, I hope it works with T-Mobile VoLTE.

Hey hnt20.......thanks! lol
How ya been?
Well I hope it works too! But if not, it will be nice to say I got to try out the newest and even greatest Xperia phone in years!
Hope all is well with you.

Are you sure VOLTE works on T-Mobile? It used to switch "H" on calls. How about wifi calling?

Yes, 100% sure. Are you running the US firmware?
Can't seem to find wifi calling in the settings.

Unfortunately, I'm running into some errors while trying to flash via newflasher:
no usb device with vid:0x0fce pid:0xb00b !
Press any key to continue . . .
Am I missing something? I have the XZ3 in flash mode (green led, no screen on) and the newflasher.exe in the firmware directory. Am I missing something?

Did you install the gordon gate drivers? Also make sure that you installed the XZ3 drivers too. (https://developer.sony.com/develop/drivers/)
