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.

Hmmm. If the phones were physically identical I'd have done the i9100 in a heartbeat. For me the radio issue is annoying .

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.
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

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

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
I have the unlocked version sitting on my desk right now.
The only difference seems to be that the radios are not the same?
But I've been reading that the radio might be flashable so it can accept Tmobile frequencies.
One question though, can ROMs from the unlocked version be used on the Tmobile version? Thanks

From what I have read, the T-Mobile H1 can flash any ROM.
The radio flashing is an open question. So far attempts to get the AWS working on the dev / unlocked models have not worked. HTC says they have different radio hardware, but at this point it is anyone's guess if we will ever get AWS working on dev.
If you use the unlocked / dev on TMO, you will get 21 Mb on the 1900 refarmed band, and eventually LTE if you live in an area that has it. Right now there are maybe three areas with LTE.
If you got the 32 Gb unlocked, in my opinion it has no advantage over the T-Mobile model. The Dev edition has 64 gb of storage.

The tmobile version flashed to the unlocked ROM should retain AWS on HSPA+, correct? That's the route I will probably be taking. The additional LTE bands are inconsequential for me - mainly south america and Philippines.

I don't think anyone has tried that yet. I suspect AWS wouldn't work without some modification because the ROM would not support AWS. But I don't think it would hurt anything either.

Yes, flashing ROMs doesn't affect frequency compatibility. All GSM One variants have the same hardware and ROMs/kernels are cross-compatible (international HSPA-only, and EMEA/AT&T/T-moblie LTE). ROMs don't include radio software, and so far at least, radio software hasn't affected available frequency bands.

If flashing ROMs (not radios) to/from intl, US, EMEA models don't affect supported bands, I don't see why it would affect tmobile -> unlocked. Advantages would be no tmobile bloat, no hacks to please the tmobile overloads, etc.

It sounds like you're disagreeing with me or something, but yes, flashing an international ROM on tmo One is great because it gets rid of bloat, can edit APNs to enable tethering, and always based on latest firmware rather than waiting for tmo to push an update. Only downside I know of is no wifi calling. I'm running TrickDroid on mine and it works great.

Sorry, that was more directed at stevedebi's comment. Wifi calling can be replaced with SIP calling so that should be fine.
Warranty problems?
One potential issue with getting the T-Mobile version could have to do with the warranty. U.S. carriers seem squeamish about people modding their phones and threaten to void the warranty for unlocking bootloaders, rooting, etc. That said, I don't have specific info at hand that HTC unlocked phones are much more lenient but seems worth looking into.

Well, most of the new T-Mobile plans come with unlimited hotspot and WiFi calling. I'm not planning to unlock mine. My One is performing fine on the stock ROM, and TMO will update the software (eventually).
As noted above, I'm not sure that T-Mobile looks kindly on having TAMPERED show up on a phone. They might well deny a warranty claim.

Switching from H to 3G is just what the radio does; it's how the interface is supposed to work. The T-Mobile version works exactly the same way--and you can see this if you flash an international ROM on your tmo One--but tmo assumes Americans are idiots who a. don't know what HSPA+ is, and b. get confused if the radio idles at "3G" when they expect to have "4G" coverage. So stock tmo ROM just shows 4G all the time, but it is just themed connection icons really. Seems like they're right to do this, which is a bit sad.
Of course, that doesn't mean that you would be getting the same speeds with the dev edition, since even in refarmed areas, you could well get better UMTS coverage over AWS than PCS.

Not to mention that in many cases you get EDGE on 1900 even in refarmed markets.
yeah I was thinking of getting the DE because its 64gb but then I realize that with wifi everywhere, I can just upload pictures or videos to you box account, then delete them to make room, and keep installing apps I want and delete those you dont.
After dealing with 16gb in a Gnexus, you learn how to manage to space

You are right if you go to phone settings-about- network you could see UMTS and HSPS+ it swicthes between UMTS 3g and 4g HSPS+ and my 4g icon stays the same, this also happen to my old HTC one 64gb developer edition but it never showed the 4g icon like T-Mobile HTC one all it showed was 3g and H icons this happens in a 1900mhz refarm area. Look at T-Mobile HTC One as example thank god it has 1700mhz built-in that's why I got ridoff my developer Edition

Hi everyone,
What settings can I use to configure my phone to T-mobile? I have an ATT unlocked 920 and I only get E signal. At times it switches to 4G and it drops. I read many posts about changing connection speed but I don't have the option. Is there a firmware that I should install in order to get the most use out of my phone?

I unlocked my Lumia 920 at&t version yesterday. But it didn't worked with mobilicity. I don't know what's the problem. Can any one help.
It seems that ATT version, unlike Rogers version, has AWS disabled. And apparently it is not controlled by the firmware image itself, because I flashed Rogers rom. We need to find a way to turn it back on...

I still don't get this part - are phones sold by ATT and Rogers different in hardware? Because people reported using Wind/Mobilicity on inlocked Rogers phones without any issues. I was under the impression that ATT phone should also work if flashed with Rogers firmware. Is it not the case?

AWS stands for Advanced Wireless Services (wikipedia). It uses 1700 MHz and 2100 MHz bands, and only a few phones support these bands.
So there no way to enable 4g on a AT&T Lumia. I love this phone but if there no way to fix this then what the point on having a slow connection
I have it enabled after they gave me the unlock code. I haven't done anything special to enable it apart from the regular phone updates. I'm not in the USA.

Hi everyone,
What settings can I use to configure my phone to T-mobile? I have an ATT unlocked 920 and I only get E signal. At times it switches to 4G and it drops. I read many posts about changing connection speed but I don't have the option. Is there a firmware that I should install in order to get the most use out of my phone?
Thanks to anyone that can help out.

AT&T L920 has AWS 3G disabled by default. You must flash an alternate ROM to enable it.

They are wrong. They do not want people flashing ROMs on their phone so of course they'll say something like that.
Flash a different ROM to enable AWS band.

I looked through the thread and I assume this method is still possible? If I enable the AWS band will I be able to get 3g and 4g on my phone? (Currently, I have E and 4G, but my house is at the end of the 4g signal...lol.)

Yes, you will have 100% access to ALL of T-Mobile's network.
BUT the European ROM does not call HSPA+ "4G", it says H+ in the status bar. The European networks never followed T-Mobile's bull**** of calling HSPA+ a 4G network.
Look at the RM-821 column in this chart to see what each connection type will be labeled with a European ROM.
http://forum.xda-developers.com/showpost.php?p=37197816&postcount=51
If you WANT I believe you can flash the Rogers ROM after flashing the Euro Dev ROM if you want the T-Mobile connection labels. Rogers and AT&T L920 ROMs also get updates before the European ROMs, so that is another thing to consider.

I'm currently on European DEV ROM. How exactly do you folks confirm that AWS is indeed working? Can anyone please confirm that you were able to get Wind Home on unlocked ATT Lumia 920 that has been flashed to Rogers, European and then back to Rogers ROM?

If you are able to connect to an AWS network. I personally use AT&T so I can't test it out, just repeating what others have said. What I know is that people with Rogers pentaband RM-820s flashed the AT&T ROM and that disabled AWS. Flashing Rogers back didn't re-enable it. So it seems that some ROMs like AT&T reprogram the bands and some like Rogers don't. I don't know any of this for sure, though.

The most important question now is - which ROMs can reprogam these bands back. With TMo its hard to confirm you are actually getting AWS and not the 1900 MHz 3G. I'm waiting for someone to confirm that with a true AWS carrier (Wind, Mobilicity).

Yeah if you're in an area with 1900MHz 3G then it is impossible to tell I think. I do not believe the 920 has any good diagnostics app.
Reading through the forums though multiple people have stated that AT&T ROM disables AWS and that euro dev ROM enables AWS. One person stated that the euro dev ROM did not enable AWS and instead he flashed through a ton of different ROMs including some latin america ROMs before finally getting AWS enabled. It's all in the thread I linked to earlier from January.
I have an old M8 lying around that I fired up and had remembered I had rooted it and the bootloader is unlocked.. Is there a way to 'trick' this phone into thinking it's an AT&T branded phone? hboot, etc. and that will allow me to RUU something official from AT&T? I know this sounds really strange and probably stupid but.. I just can't sleep and need something to fill the time.. Can I do it?
Don't think so, radio hardware is different, not to mention the partition layout.

Absolutely not. At least not any way that is known; and your chance of failure is high (with a brick being the possible or even probable result).
As mentioned in the previous comment, the partitioning on the phones is different. If you try to run the RUU, you at best it will fail, at worst it will brick the device.
Most other M8 versions (that don't support CDMA) can be "converted" from one version to another (other exceptions being dual SIM and M8 Eye). But Verizon and Sprint are the oddballs here. Some experienced devs have been messing around with these variants from the start (to try to convert them) with no success.
Perfect! All I needed to hear! Ah well.. it was worth a shot! Just trying to get my account provisioned for LTE so I can get LTE on my unlocked devices.. I've been told, and read, that if I can get an AT&T branded LTE capable phone to just swap my SIM in it.. and let my account provision, then I'll have LTE on any device AT&T or not... Just trying to avoid a contract..

As long as the phone is SIM unlocked (Verizon version is) then you should just be able to put an AT&T SIM in, and enter the proper AT&T APN for service, as long as the phone supports the proper bands. Its irrelevant whether the phone is AT&T branded or not.
Now the underlined bit in the paragraph above is the main issue. The Verizon M8 only supports one of the four bands (Bands 2, 5, 4, and 17) used by AT&T for LTE (Verizon M8 supports Bands 3, 4, 7, and 13). So depending on what band is used in your area, you may or may not get LTE.
But GSM (2G) and HSPA (3G) should work just fine on AT&T.

That's the odd part.. My main phone is the S6 Edge from Verizon.. it's on the AT&T network and I assume my APN is correct.. But it's not picking up LTE and I am almost certain the S6 Edge from Verizon will pick up the correct band for AT&T LTE .. But it's only using the H+ speed.. What's even more strange?? When I throw my SIM into the M8? I get LTE on AT&T and verify with 30+mpbs speeds.. I have no idea what's going on...

Yeah, that is strange. According to the specs for the S6 Edge here, the Verizon version supports the same LTE bands as the VZN M8, and actually some additional bands (2 and 5) that also happen to be bands used by AT&T.
One thing I can think of, is that the VZN M8 in actuality supports some bands that are not advertised/explicit in the specs. It wouldn't be unheard of, as members here have reported some versions of the non-CDMA M8 as supporting some bands not indicated in the specs. And that band happens to be what AT&T is using in your market region. In this case, that band would seem to be Band 17 (the only band that AT&T is known to use, that isn't listed on the S6 Edge specs).
Or the other possibility, is there is just some issue with the S6 that is preventing connection to LTE (but on the same supported band that the M8 has).

Yeah.. I'm not worried about it.. I've been told that all I need is an AT&T branded LTE capable device hooked up to the account and that my account hasn't been provisioned for LTE .. I've seen this in a few places so it's worth a shot.. I ordered a junk LTE phone branded AT&T to test it out.. ordered a OnePlus 2 and will likely unload the S6 Edge (if it never picks up the LTE from AT&T)

As I've already mentioned, its not really necessary to have an AT&T branded device. I suspect the reason you've seen people say this, is that AT&T branding means by definition the phone has all the bands used by AT&T for LTE; since obviously the phone is intended for use on AT&T's network. Since AT&T uses a number of bands (4) and LTE bands being used worldwide has become very un-standardized, its somewhat difficult to find a non-AT&T phone that has all the bands. But they do exist, such as the US unlocked M8, Dev Edition M8, and Nexus devices. Also, I've seen folks used other non-ATT branded phones, which may not have all 4 LTE bands used by AT&T, but the one(s) needed in the particular user's region. Not ideal, but sufficient for some folks.
Another reason why some may say the phone needs to be AT&T branded, is that AT&T tech support won't provide you any support if you have a non-ATT phone. But honestly, I've used non-branded devices (and plenty of folks here have), and this is very rarely an issue. The folks here on XDA will usually provide you better support, anyway!
Of course, your ATT account needs to be provisioned for LTE in order to have that service. Its a simple matter, and doesn't cost anything (just need a smartphone data plan).

I've dug deeper and have to not only have an AT&T branded phone, I have to register the IEMI on my account, then swap the SIM card back into the other phone. I've got the phone but can't find a way to do this online so I'll have to call tomorrow...

Absolutely NO.
What I mentioned above (Post #3) for the Verizon variant, also applies to Sprint (both versions support CDMA - the fact you don't use it is irrelevant). If you try to convert to another version won't work, and will probably result in a brick.
Also, even if you didn't have a CDMA version M8, you typically can't convert using an OTA, it has to be an RUU.

Absolutely NOT. As already thoroughly discussed on this thread, if you attempt to install another version's radio on the Verizon version, it won't work, and you may radio brick the phone (permanent damage possible).
Different radios, different partition layout.
Don't even try it. Experienced devs have tried to "convert" by various methods and mods, and failed.
But there may be other ways (besides flashing another version's radio) to enable the band(s) you want, read on:

You can take a look at the following method, as it claims to enable Band 20: http://forum.xda-developers.com/verizon-htc-one-m8/general/lte-band-7-2600mhz-finally-guide-t2992523
Read the thread, and proceed at your own discretion. I'm not knowledgeable with changing NV values (it doesn't work on "GSM" M8 variants, so does not apply to me). I simply know this thread exists.

Far from a genius, and I don't create any of these mods. I just contribute by passing on knowledge I've gained here. Really, that is part of what XDA is all about.
