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!!

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

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.

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.

Long story short, I rooted using the Exynos Abuse and flashed the SuperNexus I777 ROM and am only getting EDGE.
My friend gave me his ATT Galaxy S2 SGH-1777. I have a local carrier that also uses GSM. So I have a non-ATT SIM card.
When I plugged in the SIM card to this ATT SGS2, only the texting and dialing worked. I didn't get any data. I talked to ATT for an unlock code (which they gave me). It wasn't until after I got the unlock code that I found out the phone was already GSM unlocked.
So I proceeded to root and flash the ROM I listed above. I am only getting EDGE data. Wifi works and as far as I know (with the minimal poking around) everything else does so far.
Am I missing something in terms of toggle switches inside the settings menu to turn on EDGE? Is this carrier specific? I don't see why EDGE would work but 3G wouldn't if I am in the coverage area.
I am doing this for a friend. I am a HTC Thunderbolt user so the SGS2 is new to me. What are these modems people are flashing? Should I flash one of these in hopes of picking up a 3G signal through the Non-ATT carrier?

Yes. Your phone is GSM unlocked; therefore it can access the Cincinnati Bell towers. However, since those are actually T-Mobile towers, you can only use T-Mobile bands. Since T-Mobile and AT&T used different bands for 3G, and the phone's radio is designed to use AT&T's bands, you can only access the 2G bands.

Sorry for bringing this up again, I was looking at the specs of the SGH-I777 (ATT's SGS2) vs SGH-T989 (T-Mobile's SGS2). It looks like both of the phones use the same bands except T-Mobile is capable of one more: WCDMA 2100. Is this the band that T-Mobile transmits it's 3G over? Otherwise they look almost identical.
Attached screenshot of comparison: http://imgur.com/8OQXftD
T-Mobile utilizes AWS (1700 MHz) band. Look better and you'll see that what you marked isn't a difference, 1700 is.

Can I unlock an i9100 to USA Tmobile services? Do I need to install a custom room to make it work with Tmobile?
I look everywhere and can't find the answer. I only see different countries rom but no USA rom.
If the i9100 is unlock, shouldn't I just put a sim card and it connects to Tmobile? I did that, it didn't ask for any unlock code and doesn't connect to Tmobile.

As far as i know it will not work for Tmobile's network because they uses a 1700 MHz band frequency for 3G. The i9100 doesn't support this band
You can try unlocking your device and try? but i think you'll only be able to just make phone calls and with the internet your gonna end up getting EDGE speeds which is really slow.
If you had the chance to trade your i9100 for the Tmobiles variant i'd do it or sell that one you got and get the TMobiles version?

Can I unlock an i9100 to USA Tmobile services? Do I need to install a custom room to make it work with Tmobile?
I look everywhere and can't find the answer. I only see different countries rom but no USA rom.
If the i9100 is unlock, shouldn't I just put a sim card and it connects to Tmobile? I did that, it didn't ask for any unlock code and doesn't connect to Tmobile.

Yes, you can use it on t-mobile. However, depending on the area you live in, you may not get a 3G signal. You may only get EDGE speeds. T-Mobile primarily uses the 1700 mhz band for its 3G signal. They are however beginning to refarm some old 1900 mhz bands that currently are used for 2G data/voice and are converting it to 3G HSPA data. Check airportal.de to see if your area will have T-Mobile 1900 mhz HSPA coverage. Hope this helps.

There's nothing to unlock in an international version. It's already unlocked.

I have similar question, I'm going to US in the next month, I have i9100 and I'm wondering what mobile network will be the best for internet to me? Is there some network with similar bands as in Europe?
