To answer your question the SGS II only works on Edge and not 3g for T-mobile.

Works fine on 3g for me!
I am also using T-Mobile with 3G (or Orange T-Mobile as it is now called in the UK).
I assume the guys that can't get it working are in the States?

No problems here
the thread starter needs to title his thread "tmobile USA" because obviously this phone does not work with tmobile usa 3g. of course tmobile in europe will work fine.
Should have written my answer with more detail :/ The SGS II works for Orange in the UK but with T-mobile US it only works on Edge.
Perhaps You Can Help with T-M 3G?

Hello. I have a GSII from UK, on T-Mobile. Tried to work with a guy at T-Mobile to figure out how to get 3G (only Edge now). My unit is rooted. I would love (and would pay!) to get 3G working on my phone. Can you help out?

If your on T-Mobile US, you can never get anything but EDGE.
Thanks for quick reply...
...not to be a pest, but does the phone I got (UK GSII) just totally lack the hardware capability to do 3G, or is it a software/firmware issue that may some day have a solution?

The UK GS2 lacks the current bands to run on T-mobile US network, since they use different bands compared to T-Mobile UK. If you want 3g/4g, you have to wait for T-mobile to release their variant in the states or otherwise change to AT&T.

Hey BostonBob... you might what to take a look at this thread. It explains the situation in a little more detail: http://forum.xda-developers.com/showthread.php?p=16356271
Short answer... it appears one-half (the upload half) of the TMobile USA 3G signal is at the wrong frequency (meaning this phone won't support it.)
I looked around to see if there's a software hack to reprogram the frequency or a hardware thing. Best I can tell...
1) The SGS2 supports a VERY wide range of frequencies. The i9100 service manual shows it clearly supports service in the 1700 MHz range... but not specifically AWS (Advanced Wireless Service) that TMobile USA uses.
2) The service manual actually shows you how to go in and 'fine tune' the frequencies if you have superhuman soldering skills.
3) Bad news, even if you hit the right frequency, I'd assume the antenna firmware would have to be changed (well outside of my area of expertise.)
I keep hoping that someone with some knowledge of programming one of these antennas will chime it, but no luck yet.
Now that TMobile USA is releasing their bastardized version of the SGS2, maybe we'll get lucky and the telephony portion of the hardware will be interchangeable (though I highly doubt it.)
If it's any consolation, I'm in the same boat.
I wonder if the 4G network of T-mobile work on the AT&T version of the Samsung Galaxy S II.
Thank You

Look at the bands in the specs - if you don't see UMTS1700, it won't work.
And I have NEVER seen that in the specs for ANY AT&T phone, EVER.
In rare situations, T-Mobile phones supported one (but not both) AT&T bands, but I've never seen any AT&T phone support T-Mo bands.

T-Mobile's AWS bands aren't typically supported. AWS isn't even used in Asia or Europe. T-Mobile's SGS2 does have AT&T's bands but not vice versa. But it's a stretch even calling T-Mobile's version an SGS2.
How about 3G? Does Tmobile support 3G on AT&T phone, since i read both phone have 2100 UMTS.
Thanks

Vibrant only supported one of the bands (1900), so it only worked on att 3G in some markets, not everywhere. Some markets only use 850.

No. 3G and 4G use the same bands. You MUST have 1700 AWS support in order to get T-Mo 3G or 4G. Good luck with that. Only T-mo or some Canandian phones support AWS.

You'll get EDGE/GPRS speeds. Typically between 256 and 512K. To get anything higher you'll need a phone that supports 1700/2100 of which there aren't many other than the one's offered by T-Mobile itself.
Simple answer: No.
You will only get EDGE speed on any AT&T phones. There aren't many phones with 1700 band besides T-Mobile phones.
It's funny how T-Mobile's "SGS2" supports AT&T's bands, but not the other way around. But then again their "SGS2" seems more like an Amaze IMO since it's using the darn S3 & not Exynos >:l (points at tmobile). I really wished Sammy could fix the Exynos, so it could support Tmo, because it feels wrong when Sammy teams up with Qualcomm....End of rant.
The only reason T-mo version uses Qualcomm chip is because it needs the 42mbps HSPA+ radio from Qualcomm. The upcoming LTE version of GS2 will also use Qualcomm chip because it needs to use the Qualcomm LTE chip.

The Korean Celox, on which the TSGS2 is based, is an LTE device and using a Qualcomm chip. The two recently announced Korean SGS2 models will be LTE and using a 1.5Ghz version of the Exynos chip. Samsung went with Qualcomm for the TSGS2 and Celox either to shorten time to market or the projected quantities weren't sufficient to modify Exynos. Evolutions of Exynos will continue to power Samsung's flagship phones and tablets starting with the G-Note and G-Tab 7.7.
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.
Hey whats up erybody?
Im new to the forum as well as the android flashing/modding scene as i've always had an iPhone but recently gave in to this Galaxy sII as it looks and performs amazing. The only issue I have currently is I own an ATT Galaxy sII that is unlocked and I am using for T-Mobile but cannot get any 3G/4G network at all.
This phone is rooted and running cyanogen mod on ICS 4.0.4. I have read online about people flashing there ATT Note's radio to force your phone to accept 3G/4G for T-Mobile and I was just wondering if this is possible for the Galaxy SII? I tried using the same method but no luck, can anyone possibly point me to the right modem to install if one is available? This phone is great but I cant stand this slow ass EDGE signal.
Thanks :cyclops:

First off, you're in the wrong forum for your device.
This is the forum for the i9100, the international Galaxy S2.
You say you have the AT&T Galaxy S2... Which is the SGH-I777.
Second, since ATT and T-mobile use different frequencies for high speed mobile data, most devices for ATT will only get Edge on T-mobile. Vice versa, most devices for T-mobile, if unlocked for ATT, will only get Edge on ATT's network. SOME devices you can flash a different modem, because they have the requisite antenna hardware to get the necessary frequencies.
Unfortunately for you, the SGH-I777 isn't one of them.
Unless, you actually have the Skyrocket, which is the SGH-I727. (check the label under the battery to get the exact model number) That phone, you CAN flash a T-mobile modem to it and get high speed on T-mobile's network.
Ahhh I see. When I power on the phone it displays the international model however in the menu settings it does say SGH-I777 which is why I was a little confused since there are so many differen't models aparently.
Looks like im screwd until later this year when/if T-Mobile does go good on there word that they will be acquiring new towers to promote the other frequencies for ATT devices. Thanks for the reply.

The boot screen and indeed, the about phone screen can change depending on what is flashed to the phone. So if you flash an i9100 firmware to an i777, it will then display the wrong model when booting. Which is why I said to check the label under the battery to be sure.

Not as of now. T-Mobile in the US uses AWS currently for 3g and "4g". This band requires both 1700 & 2100 mhz for data to get these speeds. The phone doesn't get 1700, do it won't get higher than Edge.
There are rumors T-Mobile will be re-purposing 1900 mhz (which the phone DOES get) for data, so if and when that happens, the phone will probably get high speed mobile data. But until then, you're out of luck for T-Mobile with this phone, and will have to use ATT to get high speed data.

Hi ctomgee and others, I'm using a Galaxy S2 GT-I9100 that was bought unlocked. I'm also getting only 2G speeds on T-mobile. Could you tell me what is flashing the T-mobile modem and how it is done? Can I try to do this so that I can get 3G speeds? If this is not possible, would I get 3G speeds if I buy a S2 from T-mobile?
On the sidelines: What do they do to the phone that the phones bought from T-mobile would work but the others won't? Is it something done to the hardware or the software? If the change is in the software, can't we try to do it ourselves - are there any online tutorials on this?

Flashing a modem is essentially changing the software drivers for your antenna. This does not, however, change what frequencies your phone is capable of receiving. This is a hardware limitation.
The T-mobile USA Galaxy S2 is model number SGH-T989 - a totally different model than the GT-I9100. The hardware is completely different. The size itself, the CPU/GPU/SoC, the antenna hardware - all different. This isn't something you can fix with flashing a modem.
If you are patient, as I stated above, T-mobile USA is in the process of re-purposing a frequency the I9100 DOES get so it will get 3/4g on T-mobile. When that happens in the market you are in is up to T-mobile.

I spent hours online chatting with support trying to get this information and they couldn't provide it. 10 minutes of internet searching and you said EXACTLY what I needed to know. Thank you sir!! Helped me a ton.
Also, just a heads up. At the end of this year (2012) T-Mobile is going to launch their 1900 mhz band towers (see: newsroom.t-mobile(d0t)com/articles/4GNetworkEvolutionVendorsSelected) so AT&T phones that use that 4G band will work with T-Mobile once unlocked and moved over.
Thanks again!

You can set the network mode to WCDMA only... but I think there's a problem with that. If you wander into an area where T-mobile doesn't have "4G" coverage on 1900mhz, then I don't think you'll have any signal at all. When it is set to GSM/WCDMA (Auto mode), it switches automatically to Edge if you don't get the "4G" signal.
