[R&D] my T-Mobile Samsung Galaxy S II shows LTE bands

Hey guys i bought the Samsung Galaxy S II from T-Mobile thinking that has HSPA+ bands I, IV and V.. like the box and website says.
Here we use HSPA+ band V (850) so, i inserted my sim card but i only pick 3G bands ( HSDPA )
Checking the bands that the phone has using *#2263# i noticed that i have WCDMA, GSM but also i have LTE bands ...
I never heard that T-Mobile Galaxy S II has LTE bands..
Any ideas why it says LTE instead of HSPA+?

YES, I WAS RIGHT! Samsung was to lazy to change the modem between the skyrocket and the T-Mo SGSII, so if you flashed one of our modems, you'd technically have a functional LTE radio.
Wow, this is crazy!

You'd have to flash a Skyrocket radio, because when I was using a T-Mobile radio, it wouldn't connect to LTE.
But that means, if I'm right, the Skyrocket and T-Mo SGS II have support for 850, 900, 1700, 1900, and 2100 HSPA+.... that's a pentaband phone.
****. YES.

Go ahead and try it folks.

Now I'm intrigued... does the roaming agreement between the 2 carriers say anything about LTE?

Your talking about the post merger agreement right? It just may... and those of us on T-Mobile may be able to hijack Lte once the agreements are in place lol.
Its cool how there are so many similarities between the two phones. They are almost identical which is great for developement.

Yeah, but I don't think AT&T would allow another carrier to roam on a very new LTE network, especially when they don't even have 10% of their own customers on the network.
And it's really cool, because they are the same phone. xD
Although, I don't know why our accelerometer is flipped.

Maybe that is the only stipulation AT&T put out there between both phones?

Hey guys..if it helps I have T-Mobile galaxy s2 and skyrocket from att ..would like to test out and see if this may work. Not to sure if there's any lte support in Connecticut area..but this would be a niffty find...thanks op

Could be, but with the short amount of time between release of the 2 phones, Samsung must have developed 2 phones, same hardware, flipped the accelerometer in one, and branded one AT&T, and the other T-Mobile.
Gotta say, that's a great way to save with development.

maybe you are right. i just bought this phone so, its probably the new version.. however.. here in peru where i am at, we use HSPA+ 850 but i cant pick that signal .. only 3G ( HSDPA ).. so means, TMO SGS II is penta 3G band but only One band HSPA+ ?

No, try this.
Go to the skyrocket forums, find the radio thread, and flash one of those modems.
If I'm right, it should kick on the 850MHz portion of the radio

Even if u have hspa+ it will say 3g on this phone because ur carrier may only be supporting 21mbps and not 42. You probably are getting hspa+ speeds but ur phone just shows it as 3g

Theoretically it should work. Lol, an ode to the original vibrant, sometimes their laziness pays off! I've noticed the sensation has LTE mentioned also. Haven't dug if it but I wonder if it actuall does support LTE ? If I'm not mistaken LTE uses AWS protocol right?

AT&T GSIII On Tmobile 3G/4G

Since the AT&T GSIII) and T-mobile GSIII) are basically the same phone I wounder if the AT&T version will work on T-mobile 3G/4G. Similar to the way the AT&T Galaxy Note works on T-mobile 3G/4G. I was gone probably by the phone out right to use on T-mobile. AT&T has it for 550.00 where as T-mobile has it for 630.00.

I don't think so because att phone doesn't support mobile's aws band but idk if you could flash a modem. I did that on my note but the speeds were horrible. But yea t-mobile is expensive I just paid 680$ for my s3 today at my retail store..
Sent from my SGH-T999 using xda premium

I don't know, i'm wondering the same thing. the phones are identical. I think it's a very high possibility that there will be rom/radio/ kernal combinations in the future that will cater to t mobile radios that we will easily be able to flash. Just unlocked mine, I think i'm gonna have faith in US GSIII development, identical hardware and eventual full cross compatibility.

As far as I know, the Att has an lte modem and the tmo doesn't. I read that even when tmo launches LTE it won't work with the gs3. But, the tmo has att hspa+ support 1700mhz and should work with att 3g no problem.

The modem for lte or hspa+ is built into the msm8960. In theory they should be interchangeable
Would be interesting experiment for someone with rooted phone to try loading the alternative kernel/baseband then applicable sim.

There is snapdragon s4 whitepaper that states modem can do lte cat3, and dc-hspa+ cat24.
Elsewhere states that the rf for common freqs range 700-2600.

Sent from my SGH-I747M using Tapatalk 2

What I don't get is why t-mobile would use a different chipset if the 747's msm8960 was compatible with 1700 aws. Especially since t-mobile is spending billions to refarm right now to make all gsm devices compatible with their network. It just doesn't make sense. Until there's confirmation, there are reasons to have doubts.

There are some reports on xda that t999 variant used the msm8260 which is similar chipset but NO LTE.
I would be interested in link wrt tsp attempt at baseband flash, especially which s3 was used.
I find surprising samsung would bother with these build variants.

He spoke about trying to flash the t-mobile s3 radio in another thread earlier with no results. Returned his and ordered the t-mobile variant. I ordered a skyrocket myself. So far it doesn't look good. But of course with radios nothing is concrete. All we can do is flash their files and hope something sticks.

Has anyone tried injecting the modem.bin of T999 to the i747M CWM flash ready file and has their phone network unlocked with T-Moblie/Mobilicity/Wind sim?

There are at least two "versions" of the MSM8960, one with the LTE support, one without. The TMO version has the MSM8260A modem, which can be verified with getprop from the terminal. In essence, the TMO version does have the newer S4 (Krait) CPU, but it does lack the LTE hardware. So, no, the phones are not identical. The TMO version does support AT&T HSPA frequencies though, but the ATT version does not (at least in the default configuration) support TMO HSPA frequencies. Whether that can be changed or not, I don't know.
From "getprop" in terminal:
ro.board.platform - msm8960
ril.modem.board - msm8260a
What does the AT&T version say?

When Amazon first posted the AT&T version on their site I read a review about it saying it would work on T-Mobiles network for voice but not data.

What they undoubtedly meant was that you would only get plain old GSM (EDGE, GPRS, etc.) with the AT&T version on T-Mobile, due to the lack of proper frequency support for T-Mobile's network. Still voice and data, just slow as hell by today's standards. However, the T-Mobile version fully supports AT&T frequencies for HSPA (no LTE though).

hack lte on non lte nexus?

I was wondering if it's possible to flash the lte radio on my gsm nexus since it has all the 5 frequencies? I read in the Samsung note, they converted the lte radio to work as 3g instead.

What happened with the note was that they flashed a tmobile gs2's baseband so they could access the AWS bands for HSDPA+...it doesn't work the other way around since the Tmo gs2 or the tmo note don't have an lte chip. You cannot flash an lte baseband because there is no lte radio in the gsm nexus

What is it that you are trying to do exactly?
The GSM GNex does not have an LTE radio, so no matter what radio firmware you flash, you will never get LTE.

Just trying to understand if it's possible to get LTE on the regular Nexus, I guess there's more than just the frequencies or baseband involved.

the phone (any phone) has to be made specific to have the LTE chip and frequencies. if the phone doesnt mention it has it, then you cant get it.

There is a reason why the LTE versions are thicker.

Will Tmo S3 work on its future LTE network?

I'm about to upgrade my mytouch 4g to S3. But I'm wondering if S3 will support future LTE network. I've heard that in future 3G network will use 1900 band and lte will be implement on 1700/2100. Can S3 support LTE in future? If not, I'll probably wait for next year to upgrade my phone. THanks.

I think the only carriers version that does not is tmobile.
Sent from my SGH-T999

No, it will not support the LTE network. It is not included in the SoC of the phone.

Oh. That sounds pretty bad to me. But I thought tmo uses 1700/2100 for its lte network and MSM8960 has lte chip correct?

I feel bad for the horse named LTE.. js

I saw they are planning LTE implementation in early 2013. Does anyone believe that? And where? Granted, they need to be able to compete so they've got to act relatively quickly, but in my experience HSPA+ ain't bad. I'm imagining I'll be ready to upgrade my S3 by the time LTE matters (Metro West Boston). Whatchya'll think?

Yes T-Mobile is slowly adding lte, the same band at&t uses. But like others have said, our T-Mobile version does not have the hardware to support it. If anything we need to use the at&t version, but we'll be missing the h+ bands.. so it's a clear cut from edge to lte... probably going to be spotty.. i would rather just stick with h+ or use s4

Yes. That's correct. TMO is deploying LTE on AWS 1700/2100 and use 1900(from ATT) for their H+ network. So that's why I'm a little confused here.
If let's say tmo finished upgrading, would the phone without 1900 band still be able to use the hsdpa+ network? I guess I have wait until they finish the upgrade.

I'm starting to believe Samsung are pushing these S3 phones away to release a newer S3 or something. $50 for a S3 with 2 year contract is ridiculously cheaper than any other recent phones on the market. It may be cheaper than S2. Companies usually do these type of moves when getting rid of something to present something newer (maybe the Note II) but to answer your answer, no. T999 doesn't support LTE but LTE does need AWS spectrum which T999 has.

And that chip has LTE capability look at the S4 plus specs http://www.qualcomm.com/snapdragon/processors/s4/specs
Has anybody opened the phone to double check?

We've already had this discussion when the phone was first released. The short answer is no.

Make sure your account has the 4g lte package. When you login to your att account should say like.
Data pro 4g lte.
If it says data pro 4g. Its not going to give you lte.
You need to have the imei of an att lte phone on your account then it will work.

I am sure that my data plan has LTE, I took it out my iPhone5 and I got LTE on my iPhone5. I have enabled the LTE and put the right APN. Still no data connection, I have not flashed it to a different modem. So what's wrong?

How to select the right LTE band? I have only select the "Network mode" to LTE/GSM/WCDMA(auto connect). and APN is that all?

You can still get retail price for the phone if it's in great condition. Then you wouldn't have this issue.

Yeah, for LTE bands, AT&T version has less bands due to their spectrum restriction: 700 MHz (Band 17), AWS, IMT, IMT-E, while the T-Mobile version have all bands: 700 MHz (Band 17), CLR, AWS, PCS, IMT, IMT-E

Incorrect-all AT&T LTE phones support Band 4 and Band 17-AT&T is predominately Band 17 and has a small Band 4 footprint. T-Mobile's entire LTE footprint is Band 4. The real issue with a TMO S4 is whether or not you can roam on AT&T LTE network when no native T-Mobile network exists-especially since T-Mobile switched many of their legacy plans with put a serious limit or outright block on data roaming.
