[Q] Bought the SM-N900 for use in the US, did I mess up?

Basically Ive had the phone for over a month now and the connection issues have been constant. The carrier I use is Straight Talk. I got a new SIM card. Ive tried every APN setting it seems. And I cannot get any help. Did I plainly just mess up and by the wrong version of the phone I needed?

Yeah. Maybe it isnt support 4g
Sent from my SM-N9005 using XDA Premium 4 mobile app

Should have gone for 9005.

When It is on GSM only mode I only get EDGE speed, and when I switch to either WCDMA/GSM or WDCMA only mode, I do get H+ but its not reliable and I frequently end up in emergency calls only mode and am frequently resending messages. What model should I get for the best results with Straight Talk does anyone know?

You need the N900A (AT&T) or the N900T (T-Mobile). GSM Mode means 2.5G (EDGE) only. WCDMA Mode means H+ (3G) only.
You can also try the N9005 if you're into tinkering and whatnot.
Your current phone most likely does not support the recommended 'fast' bands that are on US Carriers.

Do you know which one would be the best one to get? I'm into rooting and flashing Roms, so based on that Im guessing the N9005, but arent there different carrier models of that phone as well /: basically I dont want to make the same mistake
Thanks for you help

N9005 is most used internationally so more devs support this device. But the N900T also works too.
Not the N900A if you care about ROMs.

Okay then I'll pass on the N900A. Are there specific carrier branded N9005s? or are they all the same and unlocked. Sorry for all the questions. Also I barely figured out how to "thank" you >.<-

Yeah there are, and there are specific models of N9005 too with a different partition structure (Hong Kong 16GB)
You're going to have to find an N9005 not from Hong Kong just in case, even though they also sell the international 32gb version as well, and that is already unlocked SIM wise and region wise.

Also, if you come from the states, make sure the bands are supported by your phone. People have bought the n9005 from America to find the LTE bands don't work in Europe..

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.

unlock sprint

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.

Possible GSM Mod ?

I know that the sprint variant of the LG G2 was modded to work on GSM radios such as tmobile.. is there any insight on making this happen on this device ? id love to use this with tmo :good:

Discussion of this has been ongoing in the General forum. The assessment is, despite the implication that there's a GSM band in the Crystal's modem, there really isn't one, and it is impossible to use GSM on the device. Supposedly, the SoftBank model has GSM, but we can't exactly confirm that the Sprint and Boost variants are based on the exact same hardware.
http://www.softbank.jp/en/mobile/product/smartphone/aquos-crystal/ The SoftBank site says it can do international GSM as a world phone, but tests say Sprint and Boost can't. It's not exactly confirmed what's going on.
The device is set up with VoLTE, so assuming the carrier has VoLTE on their 4G signal, a GSM carrier would work just fine, but we haven't seen any luck with it yet. Software block is an assumption right now, so maybe when the bootloader is unlocked, but that's still a ways away. We've not even achieved full root yet.

Is Indian Edge+ (SM-G928G) compatible with major Canadian carriers?

I would be moving to Vancouver in 2-3 months, so wanted to know if I can pop-in a GSM sim (of one of the good carriers over there) in the the unlocked version of Edge+ available in India (SM-G928G). Which all bands it supports, any idea?
Thanks

I wouldn't be so sure. Check the band it supports for 4G. Usually Indian and Canadian carriers use different bands, so a 4G device capable in India might not work with 4G of Canadian carrier. Other than that, phone should work without a problem. If the 4G spectrum is not supported, your data would be limited to 3G.
Check what all bands are supported in your model, you can see it here I guess. Also, check here for the LTE spectrum used by different carriers in different countries.
Hope that helps!

Try pressing *#*#4636#*#*
Once you're at the Test Menu, select Device Information-> Set preferred Network Type -> LTE/GSM auto (PRL). This is how I change my network type on AT&T. If your network/device is compatible with LTE, you should see LTE symbol below 4G symbol on notification bar.

In my AT&T model, it works. And I believe it should work just fine for any other model as well as long as its S6 Edge+. Not really sure why it's not working for you. You just need to press #*#*4636*#*# quickly in the native dialer and that should open up the menu. You do not even need to click on dial button to make a call. You can search for your carrier specific model's service menu codes in google.

If you have a CDMA HTC M8 i.e. Sprint or Verizon or other handset… 4G/LTE wont work on GSM only 2G/3G

This is false information. CDMA is a completely different network type from GSM, as well as from LTE. A number of folks have gotten the Sprint M8 to work on LTE networks (aside from Sprint). However, LTE compatibility is a tricky thing. Even with the proper band support on the GSM version M8, I've seen a lot of folks not achieve LTE on their local networks. Let alone VoLTE, which is even more complicated (carrier specific deployments, etc.).

When an M8 version is called "CDMA version" it means the phone supports CDMA in addition to (at least some) GSM and LTE bands.
Sprint is a CDMA network. There is no such thing a Sprint branded device that does not support CDMA.

Well I believe that this is not possible. Because the Htc One M8 Sprint has hardware restrictions. Then the 4G network will work if your carrier has the same bands used by the Sprint carrier. I also have an Htc One M8 Sprint and M9 Sprint also tried converting M8 to Dev Edition and almost briked my device. So really settle for 3G band or sell yours and buy a Dev Edition. If you know a way to bypass those restrictions that will a help for thousands of people like us who want to have a fully working Sprint M8 n M9 on GSM 4G LTE VoLTE ????

You're talking about a couple different things now.
First of all, the Sprint M8 already supports some (not all) LTE bands, out of the box, with no modification. Maybe the bands supported (there are many used by various carriers worldwide) are not the ones required by your local carrier. Or even if it supports the proper bands, that is no guarantee you will have LTE service on your local carrier; due to carrier specific deployments of LTE. From what I've seen, LTE support on various carriers is very tricky and there is no consistency (even when the device supports the proper LTE bands).
I'm fairly certain that some folks on here have had success getting LTE to work on their local networks on the CDMA M8 (at least Verizon). But your results will vary depending on your local carrier and the factors just mentioned. Plus, the Sprint version seems more locked down than the Verizon M8, so yet more complications there.
Second, what you did trying to convert the Sprint M8 (which you did not previously mention, and a completely separate matter) by flashing RUU, firmware, or radio from any other M8 version is definitely impossible, as you mentioned due to hardware differences; in addition to different radios, different partitioning, and different kernels. This is simply the wrong way to try to change band support on a CDMA version M8; which will not work and may (as you know) possibly lead to a radio brick (and sometimes a permanent radio brick).
There are some possible mods to modify band support on the CDMA variants. However, your results again may vary. In particular, it seems the Sprint version is not particularly compatible with such mods. But here they are, in any case. As always, proceed at your own risk, if you so decide to.
