[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?

It works great, but only shows 3G for AT&T, no 4G as it shows when it's on T-Mobile sort of 3G/4G network..
Actually quite honestly, I don't see much difference in 4G/3G difference is there when we go to LTE

No teh radio on the att version has the T-Mobile bands replaced with the lte bands so T-Mobile on a att gs3 will only werk on edge...

Can i get Tmobile 3G/4G working on Unlocked ATT

I got a ATT S3 a Gift but i am on tmobile network, i was wondering if i can unlock it and use it Tmobile Nework along with Tmobile 4G, Is it possible if i flash the tmobile radios from Galaxy Note forum ?

No. Only edge network will work. 3g and 4g work on completely different spectrum and radio frequency

That may be true about the Note 2, but an ATT S3 does not have the T-Mobile 3/4G frequencies.

Yes this guys right. Take a look for yourself:
ATT Galaxy Note Specs
T-Mobile Galaxy S3 Specs
ATT Galaxy S3 Specs
Notice how the Note and the T-Mobile Galaxy S3 have that 1700 Mhz frequency? Thats what T-Mobile broadcasts their 3G/4G spectrum on. If the phone doesnt have those frequencies, then it wont work no matter what you do.

That's different. It is a whole different phone with a whole different SoC.
Let's not say things that we cannot prove.

Don't shoot this guy completely down. It will get T-Mobile 3g/4g as soon as T-Mobile refarms their network.

Yes, HSPA+ will be fine. But as you said, no LTE.

Is the international GS3/quad core compatible with T-Mobile?

I assume the quad core gs3 is GSM? Will it work with T-Mobile 4G HSPA+? My friend is on T-Mobile and is planning to get the gs3 off contact. He wanted me to find out if T-Mobile 4G will work with the quad core version or should he just buy the T-Mobile version instead.

It will work but you will be stuck on Edge.

I'd check what frequencies it has. I'm using a T-Mobile version on at&t and get 4g data. If the international version has T-Mobile's frequencies then it should work.

Are you getting 4g lte or hspa? I don't think t-mobile s3 can do lte
Sent from my SGH-T999 using Tapatalk 2

Would this work?
Tmobile uses Band (frequency): 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band V (850)
Device Additional Information tab on that site says "Service 900, 1800, 1900, 850, 3g 2100"
But at the top of the page it says "Band:GSM 850/900/1800/1900"

T-Mobile UMTS/HSPA+ (3G/4G) mostly runs off 1700/2100 and the international model i9300 does not support the frequency we use. The quad band GSM/EDGE will work (and therefore voice/text and slow internets).
AT&T uses a more normal 850/1900 for everything but LTE, making them more "Normal" along with our Canadian neighbors.
T-Mobile is weird :-o.
If you've got access to any make of GSM based + unlocked iPhone, stick your T-Mobile SIM in it and see what speed you can get. An unlocked AT&T phone may work for testing also. We're supposed to be getting better coverage in this kinda frequency range for that but it will likely be a long time before we get sufficient coverage to enjoy a i9300.

Well put. It will be a long time before we see decent coverage for AT&T/UK phones.

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.

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.
