I've read that the AT&T version of the SGSII (Skyrocket) and Galaxy Note can be flashed with the Tmo SGSII modem and work. Does anyone know if this can be done on the international SGSII (GT-I9100)?
I have this, and was on AT&T, but now on T-Mobile. I still love this phone and want to use it on Tmo on their HSPA+ network.
I've searched, and nothing has come up. I wonder how much hardware parts these variants share with the "original".
Probably a Qualcomm Snapdragon S3 vs Exynos thing....

No. The GT-I9100 physically lacks the capability to receive one of the two necessary bands for AWS to receive high speed data on T-mobile USA's network.
The reason it works with the Skyrocket and the Note is because those two phones DO have the capability to receive both bands for AWS. (1700 and 2100 mhz UMTS)
Hey guys,
I have searched throughout the forums but have not been able to find a solid answer. I just got a Korean variant of the SG2, model M250K. I reside in Canada and am on the Fido network which is the same as Rogers. Wondering if this is a software or hardware issue. I am on the stock Korean firmware. The phone is working except I cannot acquire 3G data. Is there anything I can do to let it acquire 3g speeds here, Fido uses the 850 frequency. As far as I have read the korean firmware does not use that frequency hence I am getting edge connections. Are all of the Samsung Galaxy S2 phones built the same ie, GSM phones all have the same abilities. Would flashing to another firmware allow me to connect to the 850 frequency. Basivcally is this a software issue or hardware issue. Thanks guys.
I know it's been posted a few times before regarding whether or not the international version of the Galaxy S III will be compatible on Canadian Carriers (In my case, TELUS) but I am just wondering if it can in fact work. Here's why I ask:
I live in Kelowna, British Columbia, and my current phone is a Galaxy S II from Bell Mobility. I unlocked it back in August of last year to use it on the TELUS network. It ran on the 850/900/1900/2100 MHz bands and I had no issue with using it on TELUS at HSPA+ speeds. With the Galaxy S III it runs on the same bands, so shouldn't it work? Now I've seen people saying that it still requires the 1700 MHz frequency (same idea with T-Mobile), however in my location there is no cellular tower that supports the 1700 MHz frequency (according to Canadian Cellular Towers Map). The only frequencies in Kelowna are 850 and 1900 actually.
This being said, shouldn't the Galaxy S III work in my area if I were to continue with my pre-order for the International variant?
[EDIT]
Also, just to point out, the HTC One S, which is also just released on TELUS, also opperates on the same frequencies as the Galaxy S III International.
I think you'll be fine.
And if the international version doesn't work from wherever you buy it from, I'm sure you can return it.
That's the premise I'm going on with SaskTel.
@MaesterB: Yeah I think so too. I spoke with a TELUS rep now and he claims that the 850/1900 MHz frequencies are enough to handle up to 42Mbps download speeds, and the 1700 MHz is primarily for the LTE coverage areas (Vancouver, Toronto, etc). Of course, in my area my Galaxy S II can only hit up to 6-8 Mbps anyways so I'm not overly concerned.
Exactly.
In Regina, we have "4G" but the fastest I can get is like up to 5MB anywhere in the city.
So, the International SGS3, running on 3g/4g...should be just fine.
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.

I have unlocked (Sim Unlocked) my SGSIII I747 from Bell and it works with Rogers and all... however i do not have a micro sim from Wind or Mobilcity to test it... however i wiill go to a few stores to test it out... if it works... which i assume it should.... but there are so many factors that it might not....
However, if someone like tomin.... i cant rememebr his id can provide an interchangable flashable modem for the two phones i747 could be used on aws 1700 using the radio from t999.
See the chart on Wikipedia
Samsung Galaxy S III Model variants
I've looked at the specs sheet from samsung.com and it's the same thing.
Weve been arguing in the other thread about how t999 has msm8260 instead of a msm8960Sent from my cm_tenderloin using Tapatalk 2
Unlocked as in correect combination of software loaded on the phone to correspond with the carrier, not simply unlocking the phone. More like unleashing its potential.

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.

It would be great if we ca use the same technique to make i747 work with Wind & Mobilcity and make it just like T999
Any Luck>>>
it's good finally there's not that big of a difference in hardware and looks vs the Galaxy s2. too many variants makes it difficult to buy any accessories
The Snapdragon 800 includes a built-in cellular radio. Some phones that use this chip support all/nearly all common carrier frequencies. Other phones that use it support only certain frequency bands, usually those of the particular carrier that is selling the phone. I have seen some speculation that the chips in all of these phones may be capable of supporting the full list of frequencies, and that the carrier-locked phones simply disable some bands, possibly via firmware.
Does anyone know whether or not this is true? If so, has anyone looked into whether or not it might be possible to reconfigure which bands are available in any way? If it matters, I would be particularly interested in using the new (A86) Padfone Infinity in the U.S., but T-Mobile and AT&T 4g/LTE frequencies are not listed in the specs.
Thanks!
Moved to the right forum, thanks!
