[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?

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.

Its kinda silly that it doesn't. Here in Canada we have a company called Telus and they have the SIIX and it has LTE & it will connect to WIND (another carrier in Canada) which has the same AWS band as T-Mobile.

MSM8960 chip supports LTE. can someone check.
So what qualcomm chip does this Tmo S3 have? Based off this teardown link its at:
http://www.techrepublic.com/blog/cr...s-easy-open-case-difficult-to-fix-display/666
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.

[Q] Buying Advice, LTE vs HSPA+ ?

Hi guys,
I'm wondering should i go for the HSPA+ on the galaxy note 2, since i hear it's more battery friendly ?
Dose the Galaxy note 2 international version support HSPA+ 1700 ? and LTE ? i really tried to figure out the differences but i couldn't.
I'm using my simple mobile in Austin, TX and they are pretty cheap and offer HSPA+ 1700, which i'm willing to go for and trade LTE for battery. is this a good idea?
Your thoughts about the white vs gray ? ,, gray looks cool
im in the us, which is a good site to order from? ,, should i buy or is it wiser to wait?
Thank you guys in advance and please help

Fellow Austinite here also excited for the Note II! I'm gonna wait for the T-Mobile version. It's going to have support for their HSPA+ network and is future proofed with LTE when T-Mobile starts deploying that, so you should be able to choose which radio you want on.

From an article I read several weeks back when the TMobile Note2 was first leaked, the TMobile version will only support HSPA+. It won't even support TMobile's LTE, when the get around to building it. So I'm waiting to see if the ATT version will cover TMobile's frequencies or how modem flashing works out.

According to FCC
The note II on t-mobile WILL support their LTE and it will be future proof.

Get the HSPA+. It is more battery friendly like you said, and HSPA+ is actually comparable to LTE.

LTE has its MAJOR benefits. I love LTE but right now, I'm gonna jump on the HSPA int'l version first.

Guess I'm waiting for the TMobile one. Also curious how flashable the modem is. It would be nice is the differences between all the phones was only a flash.

No, but remember that T-Mo is changing their 1900 Edge band to HSPA+. If you wait a couple of years than it will be compatible with T-Mo H+.

T-mobile S4 on AT&T network not getting LTE

I have an unlocked Galaxy S4 T-Mobile version but when I put AT&T SIM it doesn't get LTE. I thought the T-Mobile version had compatible LTE with AT&T. I have entered the right APN for AT&T though, anyone can help?

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?

Not to bash or anything, but I don't see why people try to use a phone for one carrier on another. Why not just sell (or trade?) your unlocked T-Mobile S4, for an AT&T S4?
You can still get retail price for the phone if it's in great condition. Then you wouldn't have this issue.
To me, I don't think whether it supports the same bands matter. Use T-Mobile on T-Mobile, AT&T on AT&T, Sprint on Sprint, so on and so forth.

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.

Just was wondering if an Unlocked AT&T samsung galaxy s3 would work on T-mobile?? I think it would as the frequency's are the same. Also would AT&T samsung galaxy s3 get t-mobile LTE???
Sounds like a dumb question. What I'm asking: would at&t GS3 work on t-mobile LTE as the frequency's look the same?? Of course if I have T-Mobile LTE in my area. And also the AT&T GS3 is unlocked but, It was AT&T with LTE 700MHZ,1700MHZ and 2100MHZ.

If you're in a T-Mobile refarmed area (1900Mhz), then you will get HSPA+ with an unlocked AT&T S3. Also, if I remember correctly, T-Mobile LTE uses Band 4, the same band as AT&T. So if there is LTE coverage in your area, you should get LTE connection, provided your APNs are set correctly.
