Hd2 on at&t - HD2 General

I have a hd2 tmobile usa version, i need a At&t friendly Nand rom. Whats the best rom out there for At&t????
Sent from my Desire HD using XDA App

as far as I know any NAND Android ROM should work on AT&T as it is not the ROM that controls this but a combination of you sim card, APN settings, and you having your HD2 sim unlocked. Wait for more replies though as I do not use AT&T and it might actually be a ROM out there that has certain things adjusted for AT&T, but what that might be I do not know.

This is true, the ROM does not control the radio. There are methods of flashing the radio to a different version, one that may work for the AT&T 3G bands. I am looking them up, but that is how you would flash the device to change the radio.
Hardware wise, the GSM module does support all world wide bands but what makes then different from one HD2 from one carrier ot another is the firmware version that is used in the phones that make them work on the network's bands. Correct me if i am wrong though.

Untrue my friend, the T-Mobile HD2 only supports the bands used by T-Mobile for 3G. If you sim unlock the T-Mobile HD2 you can use the device with other carriers but you will only get Edge for a data signal as the hardware only supports the T-Mobile 3G bands. There is a model of the HD2 that supports a different 3G band the same ones AT&T uses in the US, it is the Australian model that Telstra a Australian cell carrier released as they use the same bands as AT&T. go to "Official HD2 T9193 (Telstra 850Mhz) Discussion Thread" and you can learn more about it. I also saw your other post in another thread about trying to help your friend out getting 3G on his HD2 using AT&T. Unless he is willing to buy a Telstra HTC HD2 T9193 or have his T-Mobile HTC HD2 T8585 worked on to switch out the hardware for the hardware in the T9193 then he will never getb 3G with AT&T.

Just to answer your question, every rom is an AT&T friendly ROM, meaning, they'll allow you to talk, text and surf the internet.
What you DONT have is AT&T 3G on your tmous HD2. You'll be stuck with EDGE speed.

Thank you all 4 your help,greatly apreciated!! I'm in puerto rico where tmobile is still on Edge. But for some reason tmobile is still alot faster when it comes to receiving & sending MMS than At&t on this phone. Currently using Coredroid 1.5

its interesting they would use different hardware GSM modules for the slightly different models. I would think the radio firmware version woudl take care of that. Thanks for clarification. I assumed that all GSM modules would be built the same way.

Sadly they are not, this in my opinion is just cellular carriers trying to keep you locked to their networks cause the know most people don"t want to have to buy another device when changing carriers if they already have a good device. So they make it were branded devices can only utilize high speed data with it's intended carriers network. I think this is unfair to consumers, but again just my opinion.

I think there is technical reason. The various carriers have very different technologies. Even AT&T uses a different 3G network than T-Mobile, despite the fact that both are GSM. Sprint and Verizon use non GSM technologies that are even more different. When a device manufacturer makes a certain model, there is only so much room inside, and unless one wants a really thick and heavy device, a choice has to be made as to which hardware goes into the phone.
I'm not saying that they don't want you to stay on their network - they do, which is why they have those 2 year contracts in exchange for buying a discounted phone. But I don't think that is why the hardware is different.

The Dream are all equal?

Good evening to all. has been a while I'm thinking of buying a Dream, and I'm looking at the prices in stores. I buy it again seems a bit expensive, so I turned to ebay and I saw that second-hand cost rather less. Now I'm wondering though: if I buy it outside of my country, like in America or in Germany (for example) can still use it in my country? or just not working. I ask this because I am about to go on holiday in America and I do not know whether to buy or not ...... You know where this goes from country to country?
be careful on eBay, lots of look alike phones are appearing! Make 100% certain it is truly a HTC phone!
No, that's ok it is that you resemble is fine, but for sure I care what you purchase, I do not want to buy it is a clone. However, then the Dream are all equal?
Ebay is ebay. People are trying to get the most money for their item. Some people will start lower prices than other. Some people are luckier and have more people interested and bidding higher. Some items are in better physical condition.
As others have said, don't accidentally buy a clone. They are VERY sneaky. You need to watch out for all the details and features and make sure nothing is missing.
But I am sure however that a German or American Dream can go well in my country?
the dream is a world phone, so it's going to work anywhere (gprs data, hsdpa data is only the frequency that T-Mo us runs, i think)
There are no differences between dream devices, other than the motherboard they come equiped with, and this can be the difference between been able to root and getting a brick if you try, but, again, afaik, they all come with the puny 192 mb ram and 256 mb nand flash.
I'm not sure which you want but they are NOT the same, the rogers dream will work on att 3g the tmo g1 is tmo 3g only, make sure the frequencies on the phone match your carriers...
All dreams should work, its a matter of how quickly (ie 3g or not)

Thanks for answers. If I had to take it, take the Dream brand T-Mobile or AT&T, or directy unlocked

There is no ATT branded device.
ALL dream *except* rogers will work 3G *everywhere except* ATT/Rogers. ATT/Rogers are oddball carriers with frequencies that don't match anywhere else.
Note that asides from the frequencies, there are devices with different KEYBOARD LAYOUTS. Most will have QWERTY layout (i.e. from english-speaking places), there are also QWERTZ layout (German), and I don't know what layout is used from French-speaking places (AZERTY?).
if you live in europe it would almost make more sense to buy a tmobile g1
the tmobile version has both wcdma 1700 and 2100 bands....and 2100 should work where you are...so you won't lose 3g in the deal like you would with the rogers dream

A "tmobile g1" *** IS A DREAM ***, so your statement reads as "it would almost make more sense to buy a dream [than a dream]", which has absolutely no meaning.
And quit calling it a "tmobile g1"... tmobile is NOT the manufacturer, and "g1" is NOT the model name -- "tmobile g1" is just tmobile's way of pretending that they actually had something to do with something and tricking people into contracts and limitations on features.
As someone who is becoming rather aggravated about the continuing lack of ETA for the Tilt 2 I was wondering if a Rogers version of the Dream would be a good alternative for me?
Specifically I am looking for a smartphone with a bigger screen than my 8525, a physical keyboard, wifi, the ability to surf the web and use Logmein to access PC's, and the ability to read various ebooks (txt's, doc's, rtf's, lit's, pdf's, etc). I would also like to be able to listen to mp3's on headphones and play some bejewelled/popit style games however these are less important. I am also restricted to the AT&T network as my cellphone is on my company's AT&T plan (which is why I was thinking that the Rogers version of the Dream would be better than the other versions as from what I understand it should allow it to be compatible with the 850/1900 band?)
Anyways, I was wondering if the Rogers version of the Dream would meet my requirements or if there are any other Android phones that might do so? Thanks in advance for any information and advice and sorry if I'm not asking this in the correct place.
Yes.

My N1 gets 3G on ATT

Hey guys..my friend who hooked me up with my original N1 gave me an HD2 and another N1...when I put an ATT sim in it I get the ATT logo for service and I also have 3G. My question is what model phone do I have?
thanks.

if you get 3G with the N1 with ATT sim, then it is the ATT branded one; it wasn't made specifically for ATT (i believe it was made for one of the Canadian provider), which is compatible with the ATT 3G
btw, you have a great friend to hook you up with 2 N1 and a HD2; you should hook me up with one

No, the N1 that works on AT&T was made specifically for AT&T.
The HD2 that works on AT&T was made for Telstra... or you are thinking of any 3G phone made for Rogers.

You're both wrong? The Nexus One was made and sold unlocked, it has the bands 850/1900 which at&t and some canadian providers use, not specifically made for one carrier or another
https://www.google.com/phone/choose?hl=en&gl=US&s7e=

How am I wrong? The AT&T compatible Nexus One was approved by the USA FCC, with the specific intent of it being sold as the AT&T compatible Nexus One. It does happen to work with other carriers, just as the T-Mobile version works with other carriers as well.
But there is no reason they would pay the money to get it approved by the USA FCC if it wasn't being sold specifically for AT&T customers.
As well, the Nexus One is made and sold unlocked with the option of T-Mobile 3G bands or AT&T 3G bands... those bands happen to work with other carriers as well, such as T-Mobile working with a Canadian carrier as well, just as AT&T works with another Canadian provider, plus both phones work with any carrier outside the North America... so was the T-Mobile version made for O2? Was it made for Vodafone? No, it was made for T-Mobile, just as the AT&T banded device was made for AT&T, and just happens to have carry over support for other carriers.

maybe you are not aware of how the FCC testing process goes, but there are phones that are never even sold in the USA, like euro phones, or phones from the far east, that still go thru FCC testing, yet they dont even have the proper bands for the USA 3G networks.
so the nexus one was not specifically made to be released for ATT. i dont know where you're getting that info.

You're confusing "compatible" and "designed for".
Carrier 1 uses Frequency X
Carrier 2 uses Frequency Y
Just because a phone that works with frequency X doesn't mean it was created solely for carrier 1.
GSM is an "open" network unline sprint's and verizon's CDMA networks.
Take "world phones" as an example, they work on Carrier 1 and 2, but it wasn't designed specifically for either.
There is ABSOLUTELY NOTHING HW-wise in Nexus that is carrier-specific.
Nobody makes a phone for a specific carrier, carriers only brand phones. Phone is made for a range of networks, and Nexus has 2 options, basically - because it utilizes 1 of 2 chips, either QSD8650, or QSD8250, and those are adjusted for different ranges (specifically 850/1900/2100 or 900/AWS/2100). On the Google choice screen, read: "Compatible with XXXXXXXX".
There's 2100 coverage in most of the world, so both versions of Nexus can be used outside Americas and have a high probability of getting 3G signal, since they both support it. In Americas the common system appears to be 850/1900, though.
http://en.wikipedia.org/wiki/List_of_UMTS_networks
I am not confusing anything. The Nexus One with AT&T 3G banding was made with the purpose of fulfilling Google's desire to have a Nexus One with AT&T 3G banding. Or, in other words, they made it to be the AT&T version of the Nexus One. Hence, there being hundreds of news articles and even threads on this very site using the termonology "AT&T version".
http://www.google.com/search?hl=en&source=hp&q=AT&T+nexus+one&aq=f&aqi=g10&aql=&oq=&gs_rfai=
Also, from Google's official statement on the matter:
"starting today, an additional version of the Nexus One is available from the Google web store that is compatible with AT&T's 3G network. This new model can be purchased as an unlocked device without a service plan."
http://www.tgdaily.com/mobility-features/48920-google-touts-att-compatible-nexus-one
Why would they announce that they now have a version that works with AT&T 3G if it wasn't meant for AT&T?
At&t uses those bands, those bands do not belong to At&t. That's the difference.
The way to tell if your phone is the T-Mobile or AT&T version is by looking at the part number on the back of the phone.
P/N: 99HKE002-00 for the T-Mobile version
P/N: 99HKE007-01 for the AT&T version
Hope that helps!

I understand what you guys are saying, the Nexus One wasn't made specifically for any carrier, and that isn't what I am saying or did say. What I am saying is that they did actively think about which 3G bands were included in the device... and decided they wanted to make one with AT&T banding as well, and when they released it they announced they had just released their AT&T 3G compatible Nexus One, and thus it seems fair to say (and not a stretch of words, unless we want to be anal about it), that Google made it for AT&T... perhaps saying "Google made it for AT&T's 3G network" is more complete and better, but that is a potential meaning from my original statement and so forth.
And technically AT&T owns the rights to those bands in the United States. Since you like to be super specific and technical with your semantics, figured I would add that in.
They own their towers, they don't own the bands of gsm technology, those are licensed out to them.
Yes, google made a concious decision to make that phone compatible with at&t, but that's not the same are making the phone FOR at&t.

Well it was also made for the Canadian and some South American carriers. People in the USA will call it the AT&T version, people in Canada will call it for whatever carriers they have.
I think he is maybe not quite into the world of cell phones as some of us are, so when you look at it from that perspective you would think that Google made it "for ATT." That's not really the case though.

I am just baffled... You don't think AT&T owns the rights to use the frequencies they are running on? Why does the FCC auction off frequencies then? Who are they auctioning them off to? What is being auctioned off? Nothing? Is it just a big sham?
And FYI, GSM and CDMA can run on the same frequencies, there is not point to even mentioning that they don't own those bands of gsm technology... the technology aspect is whether they decide to use gsm or cdma to broadcast over those frequencies, it has nothing to do with buying gsm specific.
Also, it is fair to say, like I already explained, that they made the AT&T banded device for AT&T in that they actively decided to make a Nexus One that works with AT&T. Sure, semantically speaking, it isn't perfect... but based off what Google themself said at the launch (We are proud to announce the AT&T compatible version of the Nexus One) it is easy to see that was their driving force, not Telstra.
Dude, I guess you're one of those that don't ever read what others write, and definitely don't open links.
Go to the previous page, open the Wiki link to the list of UMTS networks, and look carefully at the "Americas" section. What will you find there?
Ah, yes. ALMOST EVERY CARRIER IN YOUR HALF OF THE GLOBE IS USING THOSE FREQUENCIES.
Then, perhaps, you should think again, why did Google choose the frequencies as they did. Or actually, you might understand that the only thing Google chose is Qualcomm's CPU to power the phone, and this CPU just "happens" to come in 2 versions, each supporting different bands, one optimized for Americas and one for Eurasia, both including the world's most common 2100MHz band (the choice of band support can be seen in any device using Snapdragon chipset, as far as I've checked). AT&T happens to use the same bands as 80% of Americas' providers use, so?
Maybe now the "driving force" is a bit clearer.
Oh well, wasted enough time trying to explain the obvious.

So you think it is obvioud Google had HTC make a Nexus One with the 850/1900 3G banding because they wanted to appease Rogers and Telstra? You have got to be kidding me. What sort of business sense does that make?
Hey, forget about AT&T and its 100 million customers, and that they are located in our home market, we want to make sure we make the Canadians and their 20 million customers happy.
I bet it is real nice to be so naive and caught up in "semantics" to believe such real world flawed ideas.

Trade T-Mobile N1 for AT&T N1?

I bought a used N1 on eBay. I totally wasn't even thinking about the fact that there are different models of the phone for different carriers. Turns out I have the T-Mobile N1, but I have AT&T service currently.
I assume that there is no kind of mod/firmware to get it to use AT&T 3G, and that it's the hardware that limits me to T-Mo? Probably more than some custom firmware or something could fix?
That kind of sucks, if so. I doubt anyone would have an AT&T model, looking for a T-Mo model, eh?
Thanks for any help, if it's even possible..
Have you looked at the seller's return policy?
No returns accepted, as stated on the item page.
I can live with it (in remorse)..
The seller didn't mention what model it was at all, either.
I don't suppose Verizon uses the same bands as T-Mo?

No, they don't. T-Mobile and Verizon use totally different radio technologies.
Go onto the Marketplace forum on XDA, and trade/sell it through there.
Put your sim card in it

Post it for sale locally on craigslist to finance a unit with the AT&T radio.

Also if you have trouble locating the AT&T compatible N1, you may also consider the Telus version of HTC Desire. Largely the same hardware, AT&T bands, but no Euro 2100 band.
Possible bonus: AT&T does not know the IMEI of Telus Androids, and might not force you to a higher cost smart phone data plan.
Thanks for your input, guys.
I'll try first to sell it locally via Craigslist.
I really think that it will be much more difficult
since they discontinued the Nexus One, and provided it through the developers only,
it has always been the T-Mobile version which is quite disappointing....
the AT&T version seem to just disappear from manufacturing all together
point I am trying to make is that it the AT&T version should be much rarer and possibly worth more on the market since there are less quantities of it
it sucks my friend I feel for you...
How is the T-Mobile N1 different from AT&T model?

Different radio frequencies and limited availability. Otherwise identical.

If you Unlock the S off on the nexus one Tmobile. You can use a At&t sm card with out a problem. I UnloCked the S off ON the mytouch 4g AND IT works on At&t s network. HMMMM. Wondering if it works.

Yes, it will function on the network. The issue is that the radio hardware is built for specific frequencies, which differ between the T-Mobile and AT&T models.
You can use one phone on the other's network just fine as a phone, but you will be limited to 2G data speeds, as AT&T uses 850/1900MHz for their 3G data and T-Mobile uses 900 1700/2100MHz.
Umm, nobody uses 900 MHz for cellular in North America... that spectrum is not allocated for that purpose here.

You're right, my apologies. The fact of the matter (that the hardware is incompatible between the AT&T and T-Mobile networks) remains intact though.
Correct 3G data frequency information, as best I can make it out:
AT&T uses 850MHz and 1900MHz.
T-Mobile uses 1700MHz and 2100MHz.
900MHz and 2100MHz are used primarily in Europe; a phone made for European markets will have a better chance of being fully compatible with T-Mobile's network in the states based on sharing the 2100MHz band.
Closer but still not quite
Read up on the AWS band. European phones will not get T-Mobile 3G at all without 1700.
But in the specific case of the Nexus One, models sold in Europe do have AWS.

I just got the mytouch 4g and i wanted to sell my nexus one. But i wanted to double check and see if i can sell it to someone on the at&t network. I currently have tmobile. I thought the S-Off was to completely unlock the phone. So u can switch between carriers. Didnt know the frequency would be different. thank guyz. Damn u HTC.

I bought a used N1 on eBay. I totally wasn't even thinking about the fact that there are different models of the phone for different carriers. Turns out I have the T-Mobile N1, but I have AT&T service currently.
I assume that there is no kind of mod/firmware to get it to use AT&T 3G, and that it's the hardware that limits me to T-Mo? Probably more than some custom firmware or something could fix?
That kind of sucks, if so. I doubt anyone would have an AT&T model, looking for a T-Mo model, eh?
Thanks for any help, if it's even possible..

What kind of shape is your T-Mobile N1 in?
I'm actually in the process of switching to T-Mobile, and I have an ATT model that I would potentially be interested in trading, but it's definitely not mint.

What's the very best version of the Note 3?

I'm using an ATT Note 2 and I want to upgrade, mainly because of the better RAM and ROM. But I'm confused by the choices and Knox and locking and all that.
I am going too want to root my phone for sure, and unlock to use on different providers.
Not to worried about the cost.
What's the very best version out there, in your opinion?

Since the LTE bands tend to be very different from one provider to another the differences are only relevant once you know who is your carrier - so you should probably look / ask in the OTHER Note 3 forums:

http://forum.xda-developers.com/verizon-galaxy-note-3

Also see this to get a start on the matter of portability (or almost complete lack thereof) among those:

Thanks. When I mean I will want to use the phone on 'other providers,' I really just mean the GSM-based ones like ATT/T-mo and overseas carriers. I understand that Tmo and ATT use different LTE bands, just hoping that there's at least one unlocked and rootable model that covers both sets of LTE bands.

Actually, the ATT and TMOBILE gnote3 cover each others LTE bands too. Infact, after unlocking your tmobile gnote3, achieving LTE on ATT should be as easy as popping in a sim card.
I think your choice would be between ATT and Tmo and I believe both can be rooted without tripping Knox. Even thought Tmo supposed to have unlocked bootloader, they use ATT rooted ROMs (since the name delavega root). Personally I would stick with the carrier: Tmo phone will give you Wifi calling, but only on Tmo network, so you can call home for free from anywhere in the world over WiFi. ATT is just beginning to test voice over LTE, no other US carrier has yet. And if you have call issues, are you going to call t-mo complaining their phone doesn't work well on ATT network, or you going to call ATT, that their network signal sucks with T-mo phone? And for example it would be difficult to buy new T-mo phone without at least some temporary t-mo service.

I do not have a lot of experience on the US market but my last link seems to suggest that the TMo version is 100% compatible with ATT LTE (and the other way around), so generally (given the much bigger bootloader freedom on TMo vs ATT) I would say that TMo Note 3 should be a good choice. It will also work on ATT up to the full 4G and worldwide for voice over normal GSM, maybe 3G in many places. Also that last link suggests that once you unlock it (which is IMHO rather inexpensive and worth it) you will be able to use (almost) any GSM SIM in the world.

Unlock S5 From Sprint To Tmobile?

I recently got the S5 on sprint and im beyond disappointed with sprints new spark and lte network out here in NY. Im considering going to Tmobile since there lte speeds are crazy good and connection is steady out here. My question is can i get my phone unlocked and bring my sprint version phone over to Tmobile? I was told by a Tmobile rep that my phone would go down to 2g speeds and its not guaranteed to even get lte. Which i find hard to believe since since my phone has the option to also go on GSM/UMTS. Whats your guys thoughts on this?

Sprint phones cant work with T-Mobile, Sprint blocks other US GSM carriers from using their phone.
Sprint phones can only be used outside of the states

Correct. Sprint uses different frequency ranges, so unlocked or not it's just not going to communicate.
ATT and T-Mobile work due to the overlap. In fact, for a while there ATT was going to purchase T-Mobile before the FCC put a halt to that.
Glad too as T-Mobile is now shaking up the market and forcing (encouraging?) Verzion and ATT to try and adopt similar measures in order to maintain customer base.

I dont think this is correct. Albeit S5 is a different phone, but I unlocked 4 SPH-L720 S4's from Sprint to Tmobile no problem using the following thread: http://forum.xda-developers.com/showthread.php?t=2530610
If S5 could use the same methods, you would get 3G and HSPA+ on the Sprint S5 using a TMobile SIM.
I was able to get LTE using a TMobile SIM on a Sprint S4 by using DFS to edit the NV to enable AWS 1700 LTE Band in NV items, then flashing the TMobile HOS and MODEM bin files - along with copying the *ril*.so libraries to the system/lib directory. This ultimately allowed me to select the LTE/WCDMA/GSM option in Mobile Networks.
Not many people know about this but I found it in an i337 thread on how to unlock AWS on a S4.

So you can get full speeds on gsm networks with the sprint version? in the US or out?
Is that right?

Has anyone comfermed this? To my knowledge the Sprint/Verizon phones are not cross compatable with AT&T and T-mobile. Some verizon phones are the exception but basicily its a no go from CDMA phone to GSM tech.
confirm
i can confirm the sprint s4 does work on tmobile with a bit of editing and following the gsm domestic tutorial on xda, however this part about the modem.bin and hlos isnt confirmed and i have done this and ended up hard bricking my devices and had to jtag to repair them. ive tried many times and always bricked so i say no go.
this forum is for the sprint s5 and i would hope we can find a loophole to get it gsm unlocked. any ideas? ive tried a few things but no luck
Theres alot of incorrect information here. The latest Sprint phones using sim cards ARE ABLE to use T-Mobile and AT&T as long as GSM is in the hardware. I dont own the S5 but for those blinding others with frequency talk I'm tired of seeing, read it and weep:
http://www.phonescoop.com/phones/phone.php?p=4408
Sprint S5 supports GSM. Now of course no LTE on T-Mobile due to the lack of the 1700 frequency,
but your 4G will be fine. Depending on where you live, you may not even care about LTE over 4G.
Sure, Sprint locks the darn thing up to avoid it getting into the hands of other domestic carriers, but
just as the Sprint Note 3 and my Sprint LG G2, a workaround has been invented. For the G2 it was as
"borrowing" the stock T-Mobile LG G2 firmware and tweaking it to boot up on our LS980. We have
about 3 different tastes of working unlocked roms, not only sticking to T-Mobile, but other carriers
reported working such as Metro PCS and AT&T. So my guess is that the S5 may need a similar
treatment, nobody wants Sprint honestly. The first 14 days (brought in my own LG Optimus G LS970)
I was with them service was glorious here in NYC. But after the 14 day "trial period" ended I was
DAMNED into horrible service, constant 3G instead of 4G, etc. Thanks to refusing to make payments
due to the disgusting service, my GS4's IMEI is basically crap, so I sold it in the same week I got it.
I should have never swapped it out for the LG OG...
Honestly, I'll thank every OP I see that "unlocks" the Sprint version of any phone for domestic GSM
use. Their silly Sprint Spark is useless, why introduce something new when they dont even have full
4G coverage here in the USA? And their agents sound like "AI" controlled cyborgs: "Oh we're sorry to
hear that, your zone is scheduled to be recieving 4G soon." Yeah right. I feel sorry for those who suffer
in other states.
ANYWAYS sorry for drifting off topic. The recap here is that the Sprint S5 IS capable of domestic GSM with some modding.
And also that I hate Sprint.
Any Updates on this
Does anyone have any news on this? I have a S5 from sprint and want to use it with tmobile or other gsm carrier. any1 have any updates on the UCCI deal i read about somewhere? I have the spc phone is rooted what do i need to do? cant bring up the service menu to change things there.. kind a lost pls help
..
lease has anyone found a solution for enabling aws bands on galaxy s5? i have the at&t active version unlocked and rooted using on tmobile but i get only edge :/
What is the verdict? Is there anyone who knows you can use it on any network? I am getting mine tomorrow and am unlocking it. Is there a way to test if they will work on any network? I have many sim cards from diff carriers.

There have been a lot of threads about this, so clearly few are even bothering to search the forum for existing threads and the wealth of information in them.
Sprint is a CDMA system like Verizon & USC. CDMA per se is incompatible with GSM, which is what most of the world uses. The Sprint S5 only supports some of the most common GSM frequency bands and moreover will have a locked bootloader and SIM.
Sprint will not unlock the SIM (actually SPC code) to allow using it with other domestic carriers. You can find third party vendors that will "SPC unlock" your Sprint phone. But then you will find that Sprint's S5 won't support any of the LTE bands on other CDMA or GSM carriers and misses some GSM bands too.
Nor can you use custom ROMs, kernels or recoveries in the normal manner due to the locked bootloader. You could probably use the Verizon Safestrap method to emulate a limited palette of custom ROMs, but you would have to do your due dilligence there and look into the details.
In short, if you jump through enough hoops, you can use a Sprint S5 on another carrier like TMobile. But it will always be marginal. You won't get LTE data speeds, you will see more congestion than those using native handsets, due to your reduced number of bands. And you may have no coverage at all in some fringe areas served by a TMB band that your handset doesn't have.

The limitation of what "bands" the radio will cover are software defined. if you look around. you can find a way to modify those defined rules.
to allow it to use 1700 LTE. although the legality may be questionable as the FCC approval for that model was not tested with the LTE. The baseband chip/radio still supports the band with the software changes

What in the heck? Who fed you this bologna? Do you work for Sprint? Cause I have various complaints for you if you do. My SPRINT G2 running a T-Mobile G2 stock rom which is unlocked DOMESTICALLY works perfectly fine with T-Mobile's 4G. I don't think many people care about LTE, getting off of Sprint alone is a huge leap for mankind (in this case G900P owners). And as it was mentioned, there are ways to get that nice LTE band for various devices with simple mods, problem is that it is NOT widely recognized yet and very few people know that the possibility exists because of various misleading posts that "its all in the hardware" and fingers being pointed at Qualcomm's techniques. Yes there is a possibility for a domestic unlock, sure there might not be LTE for it, but most people will be content with the fact that they can use their expensive locked down phone with another carrier. Honesty Sprint devices would be better off being sold for less than carriers that actually DO allow domestic unlocks. Why do we pay over half a "K" for a phone that in reality we do not completely have full rights over? Why do other carriers alow domestic unlocks and Sprint wants to be greedy and lock in all of their customers with shady contracts and decieving bills?
Thats why many of us including myself would be beyond grateful if we even get some 3G with another carrier. We have CDMA capabilities, we have GSM capabilities, all we need is some sort of domestic unlock.
There is NO third party unlock code of any sorts that will unlock a phone that is unlocked OTA. Check around for many posts from various foreign users who have gotten stuck with a useless Galaxy S5 that can only be used with wifi thanks to Sprint. Is it their fault? No. It is purely Sprint's fault for being so damn greedy. Thankfully I am hearing news that by February of 2015 all devices will be GSM and have the capabilities to be unlocked for domestic use.
Custom roms, honestly most of us are just unsatisfied with the average and like to go to the unique side. But is Cyanogenmod going to allow us to use Air Gestures and all the other cool features of the S5? Not really. Custom kernels would be nice, but many people only seek then in order to overclock their device, which this device is in particular really doesn't need any more added power (or battery drain) than it already has. Optimization tweaks might be worth it but I dont see it helping. If someone could fix the delayed multitasking transitions (switching from one app to the other at times is delayed a second or two) or the crashing browser without custom roms or kernels, then it is best not to waste time on the development of such things. But then again there are those who prefer stock android in combination with other features such as the AMOLED screen technology, but it is best to look for another device.
