Good question. I'd like to know as well. You can def unlock the TMO and ATT GSM versions and pop each others SIM's in I doubt it's the same for CDMA versions.
Isn't the bootloader on the TMO unlocked?

The short answer is no. First you divide the phones into two groups; GSM and CDMA which are incompatible networks, apart from limited overlap on the data side. Note that Sprint in particular, locks down their CDMA phones pretty tight so that it is very difficult to use them on other networks, particularly competing domestic CDMA carriers.
GSM phones, at least the higher end models like the S5 are multi band and will work on pretty much all GSM networks. However each model is optimized for a given carrier's frequencies. So your phone may roam or (if unlocked) accept a SIM from another network, it probably won't work on all of the frequencies of the other network. The effect of that may not be much in a dense urban area, perhaps a little more network congestion or slower data speeds. But in fringe areas served by only one frequency, it could mean no coverage for the foreign handset.
The TMobile model is one of the best, generally speaking, in that it is capable of operating on more frequency bands than most other models. However what is best is subjective depending on where you want to use it and what model you have in hand. The Samsung support site lists the frequency bands that each variant will work on and you can see that they vary between carriers.
Interestingly it appears that the GSM S5's are manufactured with the hardware capability to operate on all GSM and LTE bands. But the different models only enable the frequencies used on the native carrier. Which is to say marketing (or by a real stretch, perhaps cost saving) initiatives are locking us out of better roaming capabilities.

Well again what you say is only correct for certain countries in asia. Not to single you out but there is a lot of misinformation, usually assumptions on this subject and it's productive to clarify the facts.
There were both LTE and non-LTE versions of the Exynos (4 core) S3. The GT-I9300[N/T], SHV-E210K/L/S and SGH-N035 had 4 cores and LTE and the GT-I9300[N] had 4 cores without LTE support. Not to mention that various asian counties like Japan and Australia use the dual core Qualcomm S3 with LTE. So it's not as clearly delineated as you believe.
You also suggested that it costs more to add additional frequency band support to a S5 variant. But this isn't so because the S5 uses WRL-1625 transceiver chipset which has unified support for all GSM and LTE bands. So it costs nothing extra in hardware to add additional bands.
One could argue that omitting secondary parts such as an antenna in a variant intended for a region that doesn't use LTE at all (if such exists) could make unified support moot. But the reality is that increased manufacturing and logistical costs of changing the hardware provisioning on variant handsets is usually prohibitive. It's generally believed that band limitations between variants reside in firmware with the purpose of detering grey market sales and carrier churn.

No, most of the non-LTE asian carriers are using HSPA+ networks which are considerably faster than Edge. The faster HSPA+ implentations are characterized as 42 Mbps networks, which is as fast as some LTE footprints. Advanced LTE rollouts however can double those speeds.
.
I had several people ask me about real world LTE speeds. All I can say is that speeds are highly dependent on carrier networks and will vary considerably between carriers and quite a bit by location as well. One LTE network might see speeds < 5 Mbps while another may be twenty times that fast.
I am seeing 60 Mbps typical speeds with my LTE and ~ 90 Mbps with a strong signal in larger cities. Carrier aggregation which is just rolling out now (and supported by the S5) should see some networks achieving 125+ Mbps speeds.

Current Baseband Version:
G900MUBU1BOJ2 (Lollipop 5.0)
I'm wanting to roll back to KitKat 4.4.2
Does anyone know for sure if this will work with T-Mobile? It appears to have all the bands to support T-Mobile, but I guess what I'm asking is what firmware do I download if I want to roll it back to KitKat 4.4.2? A link to the firmware would be fantastic.
This is the closest thing I've found for KitKat 4.4.2 on this SM-900M S5 that I have....but it's Uruguay. All the other firmwares are for South American countries too....
Thanks in advance.

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.

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.

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.

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.

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.

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).

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.

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).

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 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???

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
I was thinking about buying the International unlocked Galaxy SIII GT I9300 and saw how it would be cheaper in the long run, but my main motivation was being able to move from carrier to carrier if I wanted to and not having a contract. I seem to be reading though that the international version is only compatible with AT&T and T-mobile at 3G and is not capable of 4G speeds at all. Also, that even American versions are not always compatible with eachother. So am I correct in thinking that if I get an international version I'll be stuck between T-Mobile and Sprint at 3Gs. And that nothing can be done to the phone to allow an International phone to work with Sprint or even an American Sprint to work on a T-Mobile network? I'm starting to think it might be easier to just get an American phone and jailbreak it.
The international one will never work with sprint or Verizon, the AT&T and t-mobile versions will never work with sprint or Verizon.
The difference is hardware, Verizon and sprint are cdma, the rest are gsm.
The international one will work with AT&T with 3g and 4g(actually its hspa+ which is technically 3.5g) and will work on T-Mobile only in 2g for now, in a few months it will work on 3g and 4g when they refarm their 1900 or 1700mhz (can't remember which) band to 3g.
No matter what you do to either the international or US gsm versions they will NEVER EVER WORK ON SPRINT OR VERIZON.

I see, that's what I was afraid of. The AT&T and T-Mobile option still seem attractive, but in your opinion will the Verizon/Sprint with a jailbreak route be better in the long term since the LTE is by far the superior option(from what I've read)? I've seen AT&T has LTE but the International version wouldn't be able to work on a LTE network anyway, would it??? I plan to download most things on my laptop and move them to the phone anyway, the only important thing to me internet speed would affect and my main concern would be live video chat, would the 3G or HSPA+ be sufficient for that? Other than talk and text the phone will be mainly used for games, movies, music and the superior GPU in the International version I think would be better for that? Are there any other phones comparative to the Galaxy III you know of that might have both the CDMA and the GSM, the "world phones" as I've seen them called?

You can't/don't jailbreak Android phones. Hard to even know what you are talking bout trying to accomplish? It's very simple.
1. Buy a phone from a carrier and use it on that carrier. That's the easiest option.
2. Buy an International GS3 and use it on AT&T 3G or 2G.
3. Buy an International GS3 and use it on T-Mobile 2G.
If you try any other options you are just going to confuse yourself.
Definitely don't get the sprint or Verizon ones, you are stuck on cdma then. The at&t one has LTE and the T-Mobile one has dc hspa+ (theoretically up to 42mbps) the international one has standard hspa+ (up to 21mbps) and I regularly get between 5-8mbps down and 2-3mbps up and I live in the country.
The gpu and cpu on the international one are better too.

I have a bad habit of using the words root and jailbreak interchangeably, I meant root the phone. I guess I have to decide how important LTE is to me. It'll either be AT&T or the International version. The superior GPU and CPU are attractive, but so are the LTE speeds. But I guess with the limited data maybe not. But thanks for your help, this clarified a lot for me.
Frequency Concern
I have the exact same problem!
I am planning to buy a Galaxy Nexus, which works for UMTS (850/900/1700/1900/2100MHz) and GSM (850/900/1800/1900MHz). I read from wikipedia that the 3G and 4G networks from Tmobile are carried on the frequency of both 1700MHz and 2100 MHz. Does that mean Galaxy Nexus can use 3G and 4G on Tmobile network?

Oh really?! Then I should sell my international version of Galaxy S II for a Galaxy Nexus. S II doesnt receive 1700MHz. I read from Wikipeida: This band (Tmobile 3G and 4G) was an area of wireless spectrum, half in the 1700 MHz (1.7 GHz) and half in the 2100 MHz (2.1 GHz) frequencies. SO I was thinking: Hey, how about getting a phone with both 1700 and 2100MHz to work on Tmobile 3G and 4G.
So you can actually use 3G? or even 4G on Tmobile? Is it so slow or weak that makes you want to change carrier?

Help, I have an I9300 and I have tried for a week to get AT&T GO set up for data. I can talk and text fine, but no luck with data AT&T says it is my phone. Under mobile network state it says disconnected. any help would be greatly appreciated. It is an unlocked international GSM phone.
I have a Samsung GT-I9300 unlocked Gsm phone. I have started AT&T GO $60 data plan. I have tried for a week now to get data with no luck. I can talk & text fine, and it works great off of WI-FI. AT&T has tried everything they can do and says it is a problem with my phone. I was previously on Straight Talk but was stuck with EDGE speeds and not good coverage. Any help would be greatly appreciated.
Hi,
So I've read the FCC documents located here: LINK
Page 1 and Page 5 are the most interesting! These state that the Verizon model SCH-i545 will have AWS band 4 (of course 13 too) which does support T-mobiles LTE network right? It never states 1700/1200 frequencies.
Thing I want to know from the pros is will this phone indeed offer LTE support for T-Mobile or and I'm just seeing things?
Also, for all the other people that are wondering if the ATT model will offer LTE support for T-Mobile as well? It will since it supports both bands 4 and 17 But wait is that AWS band 4?... the jury is out on that! -_-
Many Thanks

If I am correct, Verizon phones do not use sim cards (CDMA) and AT&T and T-Mobile are GMS (sim phones). So even if the bands are supported, I don't see how a Verizon phone would work on T-Mobile or AT&T unless they are CDMA / GSM dual phones. And even then they would have to be unlocked.

All of the major Verizon releases over the past year have come GSM unlocked. They are world phones that contain GSM and CDMA radios. I'm using a Verizon iPhone 5 on the Straight Talk (AT&T) network currently.
All lte phones have sim cards as it is a gsm technology. My girls verizon gs3 has a sim. As far as it being compatible that is a hell of a question.

Yes! I sold my iPhone 4s to get Samsung galaxy s4 and it sold to someone over in the UK world (Ireland) that says it works! Lol.
I've also seen threads about sim unlocking the Verizon S3 for domestic and international use. Some people use HiAPN as system app along with other steps and viola... Working on whatever network you want
Question is... Am I seeing right that Verizon S4 will support AWS Band 4 for t-mobile?

Hey this is one question i have lingering on my mind. How is the StraightTalk connection? Is it any good? Are there call drop issues? And do they have data plans?
if i buy a tmobile s4 will it work on verizon??
I know most things are under the catagory of speculation/rumor but i was wanting to to check out tmobile network for a bit.... the no contract is appealing. If i bought the phone outright and ending up not liking tmobile i would switch to verizon. Short of selling the tmobile and getting a verizon phone i was wondering about just activating the same phone on verizon?
Will there be "one phone" in US or would they all have thier own modem chips i guess is the real question....
thanks for the guesses and speculat'n!
You have to consider its Verizon and they have 700Mhz LTE and you can't roam on AT&T's 700Mhz so I would not expect to access Verizons AWS spectrum on T-Mobile or vice versa. Remember when they said LTE was the unifying spectrum to allow for easier use across networks and carriers, well that was a pile of BS.
Great news, but I heard verizon was purposely going to burn in their logo onto the amoled screens.

Wrong: those "700mhz" frequencies are different bands. Both T-Mobile and Verizon are building out LTE on the same band: 4 (AWS). They will be interoperable device-wise.
AT&T also owns a lot of AWS, and though they're currently running LTE on it only in one market (somewhere in Oklahoma IIRC), all their LTE devices do come with band 4 enabled.
The more I read about the differences, the more I'm convinced that the Verizon model is more cross compatible with all other services. It's still the only CDMA model. But it's also gsm unlocked if you know how to program APNs. Any thoughts?

if we ever get to the point where we don't need 3g at all any more (CDMA) and we can get VoLTE and use the LTE band exclusively that will eliminate a lot of the incompatability between Verizon and GSM carriers .

When we get to that point, Verizon will basically be a GSM carrier. Considering LTE is just an evolution GSM, both developed by 3GPP.

When it gets to that point, the question is will LTE then become open so Google can sell a Nexus that works on every network without carriers involved?

Not just Google...all the manufacturers could do it. But...don't get your hopes up. That situation is not in the carriers' nor major manufacturers' interests, and they sit on the standards bodies. No one represents the users/customers.
