[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?

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

If that was true the galaxy note from att wouldn't get T-Mobile 4 g which it does when flashing a blaze 4g modem I also want to know if this will work on the att s3

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.

Yeah, because they live in one of the small parts of the US that uses the 1900mhz band for HSPA. It will not work everywhere else.

What about the other way? A T-Mo SGS3 on AT&T? What does that get you? I know NO LTE but what about HSPA+ ?

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

I'm hoping you fellas will help me out here.

I'm buying an unlocked T-mobile Galaxy s3 from a really nice guy. I'm on AT&T, and would like to A) confirm it will work on HSPA+, and B) I would like to know how to go about setting it up on the Medianet plan.

Someone may correct me but I don't think HSPA+ will work on ATT. They use different frequencies. If you had the international SGS3, HSPA+ would work on ATT.

OK thank you, I'll pass on the GS3, I'll just keep my iphone

It works. T-Mobile s3 has the frequencies needed. My s3 is T-Mobile unlocked and using it with at&t.

+1. The T999 supports 850/1700/1900/2100 for HSPA+. Therefore it will work on Atts H+. I use both T-Mobile and straight talk on my t999.

I assume that is something to do with at&t if so, you would have a better chance asking there.

Unlocked AT&t GS3??

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.
Thanks

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.

No tmobile lte. Bands aren't supported. But you should still get service. At least HSDPA I believe.

NO its not about having LTE its about which band the phone supports and if your area supports the same band. The Korean phone does not support the T-Mobile bands.

Ask you T-Mobile related questions here: http://support.t-mobile.com/message/283148
I posted asking about the ATT version but you can see in T-Mobile's reply is shows what bands they do/don't support. Hope this helps.
