Just like on the Samsung Infuse 4G, ATT's radio on the SGSII restricts the band selection\alternate carrier selection when using different SIMs .... are there any radios yet that can be flashed to disable this limitation yet? Flying to Asia tomorrow so would be nice to have the ability.
As far as I knew it has nothing to do with the Carrier software (at least it doesn't with non-android phones I have. They have a manual selection menu hidden, it's just the SIM locks it down.

Well if a sim locks it down that's a carrier restriction
If all you want is Sim unlock, get your Sim unlock code. ROM or modem won't make that happen.
There are a few ways to unlock your phone. Do a search.

Not to be rude but there's more to it than that... I travel internationally weekly and you're correct when it comes to using country specific Sims in thosecountries bit not when it comes to using a "country x" sim in "country z" on an att phone. I went through this with infuse too and flashing Rogers radio solves the issue. Its an att imposed limitation.

That is because if you are using AT&T Sim, there is a built in preferred carrier list from
AT&T to keep the cost down, to At&t, not necessary to you.
IIRC, if you Sim unlock and use a local Sim, you will have the option to manually select network.

Right and that's why I said yo don't understand because I'm not referring to att Sims. Its a function of the radio and affects any sim hence why I had to flash the Rogers radio

Known as a PRL (preferred roaming list) but this does not effect the ability to use a different SIM. The PRL is on the SIM not on the phone. Typically, you have the option on the device to ignore the PRL and do a manual network selection but only if the subsidy lock allows it.

You should be able to remove the subsidy lock without having to change the modem firmware. As for the band selection, a modem from the international version of SGSII is probably your best bet. But do a search to see what happens when applying different modems for overseas use.

Yeah, that's the issue is I need to be able to select a carrier. The phone is sim unlocked, but it's preferring a different carrier than I need to be using. Any way to free myself from being able to get the international version? Won't the International version not have the appropriate "4G" AT&T frequency\technology?
Thanks!
As a side note, I'm in Bangkok at the moment. I just grabbed a dtac one day sim (cause using local sims work, it's just when using foreign roaming sims i have the att issue selecting a carrier manually), and whatever category of HSPA+ they're using is rockin no a mofo... I'm getting 11mbps down and 2.44mbps upload. Now THAT seems more like "4G" than anything we have back home in the US, hehe.

Not true, on the Infuse and this phone, it's ATT's radio that prevents manual selection of networks. If you take an infuse, and unlock, then try to manually select a network operator, the menu is grayed out. If you then flash the rogers radio, wa=lahh... the network selection is available.
Yea, this restriction has nothing to do with the SIM. It's the AT&T-customized radio that's in our phones. The AT&T Android also removes the 3g/2g toggle, but that has nothing to do with the radio, and is a simple Android tweak.
I think we're gonna have to wait and see if an I9100 modem will work with our GS2s and if it will support both 850 Mhz and 1900 Mhz WCDMA...

Yeah. I'm finding that it's not a huge deal anyhow w\ Google Voice. More and more while travelling I want to use my phone for internet, and thats never cost effective for using a global roaming sim like Tru anyhow. Here DTAC, the biggest carrier just turned on "4G" (funny enough they call it 4G+ haha), and I'm getting 10mbps+ down and 2.5mbps+ upload. It's crazy-fast compared to my ATT at home. And for 30 Thai Baht per 24 hours it's unlimited data and unlimited local calls. Can't beat that. Here until Friday, so for $5 I have a week of amazingly fast internet.
Question for you. Does the International unlocked version have the ability to use the same HSPA+ frequencies and work fine on ATT? I like that idea if it does, seems a lot more people developing for it. But I'm not sure I can give up having 4 capacitive touch keys having had them for 2 phones now, hehe. A physical button just looks so old-fashioned, hehe.
Thanks!

International version of GS2 has quad-band HSPA+ radio (supports all AT&T bands w/o problems) while AT&T GS2 has only tri-band HSPA+. If you travel a lot internationally and want local 3G/4G data speed, international vesion is a better choice.

That may not be the case.
The Captivate had a published "tri-band UMTS radio w/ 850/1900/2100" support, but in reality the radio supported 850/900/1900/2100. Suspect it's the same case with the SGH-i777. Further, the potentially missing UMTS/WCDMA band (900 MHz) is used in very few places, and almost no where exclusively.
But back on topic:
When I have some more time and feel like mucking around, I might run through a bunch of different i9100 modems and see what happens.

In US, i9100 is around $550 to $600 but none of them come with any US warranty, only international warranty which ironically excludes US.

This same thing is true with the i777. And turning on the 900MHz band is done with the same method. Not sure if it will stick though.

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.
Do these two phones have identical hardware but different firmware, so that flashing for example the CM9 mod would make them identical, or do their hardware differs from each other, considering different band support and lack of LTE on T-Mobile?
Thank you.
For the most part hardware seems yo be same... you may have to switch the modems though. Expect a common Cm9 base and then a zip flash for each service provider.

Hopefully there will be some good collaboration between the ATT/Tmo (and possibly some parts from Sprint/Verizon) devs since the hardware is so similar.
It opens up the possibilities for a lot more ROMs!
Actually my question was more about the possibility to use the devices across the networks using custom mods (e.g. to use the I747 on the T-Mobile network).
Thank you.

You can do this without mods but you won't have access to the 3g band on TMo just like TMo won't have access to the LTE 4g ATT Band...flashing a diff modem/radio won't give you the missing bands unless the hardware actually supports them and its just locked out...which currently isnt known.

It's a very valid question… the AT&T Galaxy S III is $550 out of contract; the T-Mobile version, $630.
If you're paying out of pocket, $80 less for what amounts to the same device (arguably, the AT&T one is better since it has an LTE radio) is nothing to sneeze at.
I am having the same question as well.
The situation here is the same to what I have as Rogers/Bell/Telus vs Wind/Mobilicity
I'd like the flexibility to use the phone across the network since the new carriers charge way cheaper than the big 3....
I suppose the hardware between the two model are identical. All support the same band 850 900 1700 2100 (AWS/LTE). Only the AWS version has the LTE radio disabled and HSPA 42 enabled???
It should work, the phone is locked to att thou. You will have to have it unlocked. But the skyrocket and the hercules were interchangeable between networks. But the international will not work on lte or Hspa.

So you are saying that that radio modules of these two phones are identical. Meaning that T989 supports LTE, and I747 supports the 1700 band (they just have to be unlocked).
I'm gettin mine unlocked and using it on straight talk t mobile. I need to get that hspa 42 workin. It's just software. From what I gather, once t mobile rolls out their LTE they may just release a firmware update enabling LTE on the t mobile galaxy sIII's. This phone is a seven band monster world phone. To such an extent that carriers are turning features off.

All the radio modules on this phone are integrated in the S4 processor. And the processor is identical. One would have to conclude, that yes, that is the case.
From a strictly electrical background the modem is software running on transistors which can handle being pushed to the frequencies T-mobile requires, so I would think that it would be doable with the right software. When a transistor has the ability to handle the current and frequency the rest would be a matter of software, I assume.
As for LTE I have no knowledge as to the hardware or if there its something missing in non LTEs.

It is interesting as its normally a possibility with Galaxy devices. This is a bit different since they have used slightly different models. We won't know until we get flashable radios and someone is brave enough to try to flash it on their device. I know with the Skyrocket I was able to flash a T-Mobile radio and get a 3G signal on wind (same type of network but in canada). The only limit was that you couldn't take a t-mobile version, flash at&t's radio and get LTE.

Do you guys think the devs will be able to enable AWS HSPA bands on the ATT / Rogers / Bell / TELUS devices?
Many of us in Canada use Roam Mobility (T-Mo MVNO) when we roam in the USA. Having access to AWS + 1900 HSPA would be great so that we're camping on 2G less often.
It is in there, the problem is unlocking it. ATT may have required an efuse based lock that cannot be changed once set at the factory.

Interesting thing is htc has listed data speeds for canadian version via hsdpa is up to 42mb and it's the same for t-mobile USA, only At&t has different one. This could mean, that Canadian version might be similar to T-mobile version. But, this could just mean at&t's network doesn't support speeds of 42mb on hsdpa. I'm leaning toward network limitations.. But, I'm hoping I'm wrong haha

That's great, but Samsung's lock was superficial, incredibly easy to bypass. Maybe flashing TMOUS radios will do it, but there's no guarantees and it requires S-OFF.

We know, but the hack or mod will allow us to keep the latest radio's released modded for all frequencies.

Honestly I don't think this is something worth investigating until S-OFF is achieved. Then we have to figure out whether or not the lock on AWS WCDMA can be removed with software means.
The iPhone 5 had the same exact problem. For T-Mobile they released a phone with the same model number as the ATT version but with AWS WCDMA unlocked. Apple was unable to do anything for the ATT users because the lock went so low level that no software could change it, so they had to just change the software from the factory instead.
The same thing may be happening here.
Has anyone figured this out yet using the QPST method in the Qualcomm software like we do with Samsung?

Does anyone know if the AT&T HTC One has the 2600 Mhz 4G/LTE band?
The International model does, but not sure if after converting the AT&T one changing the MID, CID and RUU will unlock the band.
I'm using an at&t sim in this phone but it won't use their lte. Is it possible to enable their band on the Verizon chipset? Is the chipset simply software limited or is it a completely different chip?
I'm wondering if flashing the AT&T modem is an option.
It depends upon what your phone is capable of and what services are in place where you live if you have a 4G phone and still no lte try a signal booster it will refresh your connections and refresh your network

Never flash another modem from another carrier. By searching this very topic you will see that you may not get a signal again after trying, or a brick.
Also no. Radios on hardware level don't support the att frequencies and bands for their lte. Att lte uses 700 and 1700 for the freqs with bands 17 and 4 respectively. The schi605 only has lte for 700 mhz on band 13.
