I recently purchased an unlock galaxy s2 i9100. It is supposed to be GSM unlock with HSPA+ 21Mbps/HSUPA 5.76Mbps, EDGE/GPRS Class 12, Quad band GSM 850/900/1800/1900, Quad band UMTS 850/900/1900/2100 hardware capabilities. since I have gotten the phone i have not been able to connect to anything but edge. Tmobile assured me i had the correct APN setting. I would like to know if anyone know what I could to to enable the HSPA+ T mobile US uses UMTS 2100 to connect. I rooted and flashed the lite'ning rom.

I am a bit of a newby and would appreciate any advice.
Nope you won't get hspa speeds on Tmobile with the current international version. You have to wait for the Tmobile variant. International version gets
3g speeds only on att.

This is correct. However, it's only used for one way traffic (either uploading or downloading, i'm not sure which). UMTS 1700 is used for the other direction of traffic on T-Mobile. This means no 3G/4G without both frequencies.
Your 2 options:
1. Get a T-Mobile phone.
2. Switch to AT&T.

thanks for the quick and concise responses. I have a clarification: does this mean that I when Tmobile comes out with the variant my phone will be able to upgrade to Hspa via a rom or radio update or that if i want to keep this model i will have to wait to swap it out for the tmobile version

The I9100 will NEVER work on T-Mobile. The SGS2 that they are releasing has different HARDWARE. There will never be a way to make the phone you have now work on T-Mobile 3G.
As others have said you'll need a different phone in order to get it to work on T-Mobile USA's 3G/4G frequencies.
You'd need a penta-band phone in order for it to work on all of them. I think Intel is curently working on that or already did but that's all there is. You'd need both 1700/2100mhz in order to use it with 3G.
I don't get how people don't research before they buy!!

I know that $60 unlimited plan with T-mobile provides me with 2gb of Data however, I can never get H+ or H or 3G at all. All I get is edge is there an issue with it? Can anyone help me?

Which Galaxy SII do you have? The T-Mobile version you get directly from T-Mobile? (SGH-T989) Or the International version you bought unlocked? (GT-I9100) It makes a difference. The International version (GT-I9100) doesn't have the hardware to pick up T-Mobile's 3/4G bands, so you would NEVER get H+, H, or 3G with that phone.
If you have the T-Mobile version (SGH-T989), you're in the wrong place. You need to be in this forum.
I have the international version but i thought that t-mobile freqs are 1700 which is AWS and 2100 IMT?
or is the 2100 band AWS as well?
edit:
GSM arena states that the t-mobile vers is 850/1700/2100 and the eu vers is 850/900/1900/2100
I know that 1700 isnt supported but isnt 2100 workable?

That's like trying to walk with one leg, not gonna happen, you need support for both bands kinda like what the gsm galaxy nexus has.

Agree with what peachpuff said. And if I remember correctly, T- Mobile uses one of those bands for upload and one for download. So you would definitely need both.

Let's say you're in the U.S. and you've got the international i9100 SGS2.
And let's say you can't get an AT&T signal in the place where you most need it.
You might well say screw AT&T's 4G speeds (which don't seem all that fast anyway), just give a freaking signal.
You might then go with a pre-paid, or a pay-as-you-go, or whatever, T-mobile 2G/EDGE data plan, because it's the only thing you can do.
The situation sucks, but you have, AFAIK, no other choices.
Hi, I have the white s2 i9100unlock version and when I put in my
Tmobile Sim card it says that I am running on E network instead of 4g. Is there anything I can do to change this? I contact Tmobile and they say it's the phone not their line. Please help me out because running on the E network is very slow
Sent from my GT-I9100 using XDA App
The international i9100 does not support 4G. Only option would be to get a 4G enabled one.
its because the international galaxy s2 doesn't have the same 3g bands as T-Mobile (assuming you are T-Mobile USA). They run off of 1700/2100 while the phone itself supports 850/900/1900/2100. While only the 2100 band matches, if you don't get 2100 coverage in your area, you will default to 2g.

So you started another thread on this, where I also answered your question. This phone will never get HSPA+ speeds on T-Mobile USA - or what they call "4G". It lacks one of the necessary frequencies for it. It will only get Edge speeds. From what I remember on how T-Mobile USA's network functions, 3G and "4G" need both 1700 and 2100 mhz to function, as it uses one frequency for download and the other for upload.
EDIT: Here's the wikipedia article on AWS, which is the band T-Mobile uses for 3G/4G. In brief, AWS uses 1700 Mhz for uplink, and 2100 Mhz for downlink. So since it only gets half of the band, it won't do "4G".

Unfortunately, the bolded/underlined part is simply not true. T-Mobile USA needs your phone to be able to get both 1700 mhz and 2100 mhz UMTS frequencies to do 3G/4G. If your phone doesn't have one of the frequencies, it won't do 3G/4G at all, and fall to Edge (2.5G).
What if I overall another ROM? Will it help?

No. The phone simply doesn't have the hardware to receive the frequency. Nothing you can do to fix this.

You need Galaxy2 HD LTE to access 4G. That particular model is not available outside Korea at the moment. If you want 4G, try Samsung Galaxy Note or LG Optimus LTE - also known as Nitro HD, or HTC phones.

That indeed is weird and inconvenient, but I guess telco's can setup their system however they like... It may have lot to do with number of people using mobile services. In OZ we have 22 million potential mobile users using 4 major telco companies, whereas in USA, they would get most of OZ population just in New York city, let alone rest of the country.
Ah systemcrasher I think they might be load balancing the hspa+ mimo across the two freqs. Telstra nextg doesn't need to coz there's allot less people here.
If that's the case still should be allowed to fall back to a non mimo mode.
Let this be a lesson to the OP, always research all carrier pre requisites before buying, also consider other carriers encased you'd like to stay open to other options.

So the answer is the link to the wikipedia article in my quote above. It's not T-Mobile USA's doing per se - they just purchased the AWS-1 (also known as UMTS band IV) band of the spectrum. That's just the way this band is set up. Wind and Rogers in Canada also use this band.

to put it plainly,
NO
the i777 does not support the required bands for accessing TMobile's 3g/4g network.
Had the merger gone through, possibly. But as of right now, no.
Tmobile is on 1700MHz and 2100MHZ while AT&T is on 850MHz and 1900MHz.
No, and this is the case for every AT&T device in existence to my knowledge.
In fact, the ONLY device I know of that is not sold by T-Mobile and supports their HSPA bands is the GSM Galaxy Nexus, which is one of the first (if not the first) phones to do pentaband HSPA.
Personnally I tested the Unlock Process with a T-Mobile SimCard...not sure if working properly due to a operation range described by the fellows

You can still get 2G on T-Mo because T-Mo uses the standard 850/1900 for 2G. What OP asks is 3G/4G.

How is that an exception to what I'm saying. The T-Mobile version is not a device sold by AT&T, and is, by definition, a device sold by T-Mobile.
It's always been a bit easier to get T-Mo phones to work on AT&T - a number of them support the AT&T bands. But it's never been easy (and with the possible exception of the Skyrocket, never even possible) to go the other way without losing 3G.

That would be the obvious answer based on the published specs, but I found an unselected listing in the hidden modem/ band settings for WCDMA 1700 MHz (Band IV) on my i777. I don't know if it works, but it's listed. From the phone keypad on the stock version, type in *#2263# and then look under Combinations. The phone lists 7 different GSM/PCS/WCDMA frequencies and only the obvious 5 are selected.
Anyone with an unlocked i777 on Tmo want to try it out?

Unlikely. Unless the phone has the hardware support for it.
I found out after extensive research on the Nexus One, that even though the radio chip inside it supports both frequency sets (pentaband, I suppose); the power amplifiers were only connected to certain frequency outputs, depending on the carrier it was advertised for. Which means even if I flashed a T-Mobile radio, the signal wouldn't be strong enough to get outside the case of the phone, let alone to a cell tower.
Your best bet is with European phones, as I believe they use the same frequencies as T-Mobile (since they're owned by a euro company).
Someone should confirm, but I would guess that the I9100 will work on T-Mobile with 3G.

No, WCMDA = UMTS = pure vanilla 3G.
2G = GSM/GPRS
"2.5G" = EDGE
3G = vanilla UMTS (WCDMA)
3.5G = HSDPA
3.75G = HSPA+
3.9G (it's not really 4G) = LTE
true 4G = LTE Advanced
Most phones, even if they support advanced modulation schemes (HSPA, HSPA+) will list the band support as "UMTSxxxx or WCDMAxxxx"
I heard (it's actually confirmed, can't find the article), T-Mo has the same 3G bands as AT&T in some remote part of the USA, I think somewhere in Washington state, not sure though? The OP might want to move there

That might explain why the Vibrant apparently supported one (but not both) of AT&T's bands.
As I understand it, unlike the N1, the international HSPA+ Galaxy Nexus is full-blown pentaband.
Tmo has roaming agreement with at&t. So it is possible in places there is no tmo tower, your tmo phone could roam to at&t tower without showing the roaming sign.

Excuse the noobish question, but to make sure I have this right - You need both 1700 and 2100 bands for the 3g or 4g to work at all, correct? Was looking into buying it once its released but that may be a deal breaker if no speedy internet.

Yes, you need both, or you will be stuck using EDGE if you are on T-Mobile US.
I want to know the same, if the intentional version will surely work on Tmobile.

I'd like to know about that as well
I think everyone here just wants to know when the hell it'll be coming out to our own carriers. I need a new phone but I'm not waiting until Fall for one.
Doesn't t-mobile uses the 1700/2100 for 3G and 2100 for 4G? so it would be EDGE and 4G.
So your implying that 4g will in fact work? I thought you needed both bands for 4g to work.
I'm in the Philadelphia area and really need to know if this will work or not.
If I can get 4g, ill be preordering the phone asap. If not.... I'm still undecided.
nope, im asking if thats the case. i need to ask the dude that know, since he is the manager at the t-mo store if thats rite. but t-mo one should be coming out in month or two.
What T-Mobile calls 4G is really their 3G HPSA network. They have not yet rolled out LTE. So for you to get the T-Mo 3G, you need the phone to support 1700/2100 band, which I am not sure the international SIII model does, but I'm almost certain it does not. Therefore, you will only get 2G (EDGE) speed, which is around 10-15kilobytes per second download, good enough for web browsing and loading Google Maps, it's about 3 times faster than 56k modem.
The T-Mobile-locked model will support the HPSA+ 42Mbps speed and AT&T version will have LTE of course. Now whether if when this phone get released for T-Mobile and somehow it will preemptively support their future LTE service (launch in 2013), then that would be interesting (which inherently the hardware does support LTE due to the Qualcomm S4 chip to be used in American models). What I predict they will do is like with the Galaxy Vibrant -> Galaxy S 4G, so first release the HSPA+ only version, then release a slightly modified version that support LTE.

If this doesn't confirm lack of 1700, nothing does.
So basically, count on the international version not being usable (besides EDGE) on T-mobile. You'll have to wait for them to up with their own version.
