[Q] Possible to Unlock?

Hi I wanted to buy this pone from amazon, but the thing is that I would buy the sprint versión with no contract and I don't live in the US, so my question is, can I unlock this pone to use it with any other company? like Movistar? I read that the pone was GSM so I thought it would be posible, however I won't take the risk of paying 590 dollars for a pone that I can't use, thanks

What do you mean if I dont know dont tell? What does that supposed to mean?
I KNOW my Cellular Networks!
Sprint is a CDMA Network!
The ONLY part about sprint that is NOT CDMA is LTE which the sim card slot is LOCKED to sprint.
They MIGHT be a fix but right now there is NOT. Some of the older phones like the Moto Photon its not LTE but its a world phone and people could flash a few things and make it work, But only EDGE in the USA anyway.
But as of right now and problay for a while its NOT going to work.

Thats right sprint CDMA provider YES! but sprint announce more cdma-gsm phones (like blackberry) now sprint sell locked phones (htcone , S4)and this man need know maybe he unlock phone for him country(i think he live in spain(movistar as i know its spain company! right now he not can use gsm in this phone but i think i found solution maybe via nv maybe via modem patch !

I expect Sprint will provide a method soon to unlock the GSM and UMTS functions in the phone to be able to use it internationally. However, I don't expect the GSM and UMTS functions to operate inside the US. Sprint has always disabld them on GSM capable Android and iOS devices it sells.

I don't see why it wouldn't work for you as long as you can get it unlocked.
Sprint is not going to unlock it for you unless you are a long time customer or have the phone with them for 90 days.
hyelton is completely wrong though.. the sim does authenticate lte on sprint but also acts as a gsm sim internationally.
you can also remove the sim and insert any international sim once unlocked providing the carrier uses the correct bands.

You are all kinds of WRONG.
Sprint's GS4 is fully capable of voice and data on international GSM/HSPA+/UMTS 850/900/1900/2100MHz networks. You have to request Sprint to unlock your phone's sim (or find a work around if you're not a Sprint customer), but once unlocked you can pop in any international sim and it will WORK JUST FINE on international GSM networks, they don't have to support LTE. Heck the only thing preventing the SG4 from working on US GSM networks is Sprint locked the Sim from using USofA GSM carrier sim cards.
As long as the OP can get their Sprint SG4 sim unlocked, they can pop in their international sim and use the GSM in their country NO PROBLEM like any other GSM phone.
SO ONCE AGAIN, Sprint's SG4 has a fully functioning GSM modem that supports international carrier GSM/HSPA+/UMTS 850/900/1900/2100MHz bands!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You would think someone with almost 2,000 posts and who made a statement like "I KNOW my Cellular Networks!" would know better. Do yourself a huge favor and actually know what you're talking about before you go spouting off again, because you really made yourself look like an ignorant fool.

Well YES you can easily use your phone overseas, But it was POSTED in the Sprint Forum which is ONLY in the USA and in which using it does NOT apply in the USA. And to get the phone unlocked I`m not sure if a regular unlocking company would be able to do it someone with a sprint account would and it would be MUCH more trouble than just to pick up a ACTUAL GSM carriers Version of the phone.( I should had just said that to begin with) Its VERY pointless to TRY and want to use the sprint Version when they are SEVERAL OTHER varrients that are GSM they could have got to use.

EXCEPT... the op specifically said they wanted to purchase it from Amazon America to use on their country's GSM network.
Why they want to do that? WHO KNOWS, maybe it might be cheaper doing it this way, but that is what they want to do and despite all your unnecessary wrongful information, the OP can do what they asked as long as they can get the sim unlocked.

I sell on Amazon and Most people wont ship out of the USA on Amazon. Mostly only Candia but Ive tried ordering a lot of things overseas and 90% I cant as they wont ship here

Amazon sells the Sprint for $599 this is probably why. I bought mine at Best Buy and had them price match Amazon for that price.

Looks like everyone here is an expert in this matter but so far haven't seen a single link to reputable sources... OP call sprint international department and get answer straight from the carrier (888) 226-7212
Even IF the phone is capable of being used in GSM bands internationally, you would have to get it unlocked by sprint and they change policies all the time so just call..

I got my phone unlocked for international use. I contacted sprint international services. I was initially told that you have to be activated for at least 90 days before they could unlock the phone but would forward my request to some department. After one day I got a email that my phone has been unlocked.

Yea.... but it ONLY works internationally AND you have to be a sprint customer.
The POINT I have been trying to get across is that people need to understand Sprint is a CDMA carrier and ONLY relies on GSM for LTE. I think what people think is that they are solely a gsm carrier like most of the world is but its NOT

[Q] Lost Phone, Can I use Sprint LG G2 On verizon?

I had a little too much fun on new years eve .. I set my Verizon LG G2 down on a table and apparently either I left it or it was stolen .. I probably left it hahaha..
Now i'm trying to get another one .. I really loved the phone...
I'm scouring eBay ..
I'm in a 2 year contract with verizon ..... but, I wanted to know ... Can I use a Sprint based LG G2 on the verizon network ? Will I still get verizon LTE ?
Same thing with T-mobile versions ? Can I get all the bands and function I did out of my verizon LG G2 ?
Thanks for the heads up guys.

I know that the Verizon one can use Sprint, but I am not sure about the other war around. I think the global one works on Verizon's LTE band, although I am not sure an that either. If you can afford it, get the Verizon model (VS980) off contract. You can check the bands and other specs on phone arena.
The T-Mobile one seems to share frequencies of Verizon's though.
Hope I helped.

Verizon and Sprint are CDMA carriers and run on compatible CDMA frequencies and technologies (1xRTT, EvDO) and both their branded phones can roam on/off each other's network for both voice and data.
Having said that, the fact that they're primarily CDMA carriers means that you cannot just bring a phone onto their respective networks. The ESN/MEID of the phone has to already be in their database for them to activate.
So, taking a Sprint LG G2 and walking into a Verizon store or calling Verizon to activate it will get you a big fat NO, and vice versa.
Is it technically possible? Of course.
Worth the effort/hassle? No.
T-Mobile is a GSM carrier, no CDMA, so that's out of the question, same with AT&T, or any GSM variant of the G2.
Get a Verizon LG G2. Just keep looking carefully and you'll find a good deal.
I got my Sprint LG G2 mint in box for 325, clean ESN, no funny business. Love it to bits.

You can use Sprint LG G2 on Tmobile, takes about 20 minutes

In response to this assessment I have to correct these "facts"
You CAN use Tmobile's network on Sprint LG G2 Variant. See Younggunners forum on Sprint-Tmobile rom.
http://forum.xda-developers.com/showthread.php?t=2639165
I am currently getting 4G speeds at around 14 mb on the down and 4 on the up, very workable.
I can attest that it works; I have also performed the flash on other sprint LG G2 LS980 Variants as well.

I think you missed what he was saying. He was saying that the T-Mobile and ATT variants do not support any CDMA so they will not work at all. The sprint variant supports Verizon CDMA but verizon will not activate a sprint device on their network. In any case the sprint device does not support Verizon LTE bands. Even if Verizon activated a sprint g2 on their network it would be 3G only.

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?

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.

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.

cdma. Verizon and sprint... hmmm.....

Sprint and Verizon use cdma. Will a sprint rom work on our phone? I'm almost wanting to try lt, but I've borked enough phones at this point. Has anyone tried or does anyone know if it will work?

I do believe they use completely different bands.

I'm thinking an apn would do the trick. But I have been wrong before...

i think it has to be ported but most work from my understanding but it cant require an unlocked bootloader like CM

Unlike verizon, sprint phones are sim locked for US carriers so thats a no go for LTE. On the 3G side verizon would have to allow the sprint phone to register on there network and that will never happen! Also unlike verizon with sprint you cant just pop out your sim and change phones since imei data is stored on the phone and not the sim. Oh and by the way this thread should not be in this section

activate ATT v35 on sprint or any cdma mvno

tried to run the imei number on the sprint and verizon site, says cannot be activated. Went to sprint and called verizon, says att branded phone cannot be activated. This is unlocked, works on tmo. tried searching for a solution in the forum but no dice.

Doesn't matter if it's "unlocked", other carriers have their rules for what they allow on their networks. Most AT&T phones don't have CDMA, and Sprint, Verizon (for now) still uses CDMA.
On non-branded phones you won't get VoLTE from most carriers (T-Mobile is the exception) and without VoLTE you would need to temporarily drop down to CDMA for voice calls on Sprint and Verizon.
Even on phones that have CDMA, like the LG V30 US998, Verizon still wants you to buy their branded phones -- because end of this year when CDMA goes away, those phone still won't have VoLTE. So in a few months those phones won't be able to make phone calls. I have two relatives with LG V30/V30+ US998 on Verizon. Don't ask how, there are ways. But even of 2020 they will need new phones when Verizon kills CDMA and they can't get VoLTE on non-Verizon phones.

As an owner of an AT&T v35 I can tell you it will work nicely on the Verizon network including VoLTE and VoWIFI. You do have to jump through a few hurdles. You will need a SIM activated on the Verizon network. That may mean buying a new phone from Verizon. You also need to SIM unlock the v35 by buying a code from a site like codes2unlock.com. You may also need to cross flash to the NA rom. These things should be done in that order, and there is no going back to an AT&T rom afterwards.

Even on phones that have CDMA, like the LG V30 US998, Verizon still wants you to buy their branded phones -- because end of this year when CDMA goes away, those phone still won't have VoLTE. So in a few months those phones won't be able to make phone calls. I have two relatives with LG V30/V30+ US998 on Verizon. Don't ask how, there are ways. But even of 2020 they will need new phones when Verizon kills CDMA and they can't get VoLTE on non-Verizon phones.

Chazz, can you clarify this? I have a US998 v30s running on Verizon with VoLTE. It was my understanding that it will not be affected by shutdown of cdma by Verizon. I like the phone and want to continue using it.

My brother-in-law found Verizon store rep willing to break the rules for he and my sister's USS98 V30+ (converted from Sprint LS998). They switched from AT&T to Verizon.
This guy said "Verizon wants you to buy their phones, of course. They'll tell you this phone (US998) won't work, but it will." He activated two SIM cards and put them in their US998.
He said "If you have any issues, ONLY see me here at this store. Don't talk to any other reps about this." Wink, wink, nudge, nudge. (Monty Python reference.)
My brother-in-law and sister don't have V35 on Verizon, but you probably have VoLTE because you enabled VoLTE on another phone (Droid Turbo)? I don't know if they have Verizon VoLTE on US998 V30+, but I assumed they didn't...

If you have Verizon VoLTE now, then nothing will change.
I assumed my brother-in-law and sister don't have VoLTE and are temporarily dropping to CDMA for phone calls. But I have no way of easily checking. Neither would know what "VoLTE" is nor "CDMA".
I merely told them their US998 phones were carrier unlocked and would work on Verizon -- if they got already-activated SIM cards. My brother-in-law used his considerable sales skills and found a helpful rep.

thanks a ton @chazz for the clarification. i have already move to AMZ 9.0 which looked to be pure android. was not able to get NAO due to error(sha256 auth error). AMZ was the only one that worked from multiple different firmwares(lgfirmware /sammobile) from us region and it works awesome.
For the verizon sim card, can i buy flip phone or a throw away verizon smart phone with the activated sim card and use it with the v35. similarly can you use the approach for sprint?
Again your response is much appreciated.

You should consider features you want to have on your account when buying the phone from Verizon. Some can be toggled through the the settings menu on the v35 like Advanced Calling for VoLTE, but others can't like visual voice mail. Ask to have them activated when you buy the phone. Keep that Verizon phone, you may have to get help in the future from Verizon and it will come in handy! They won't be impressed with the v35.
I don't have proof of it and am not in a position to test, but I suspect you cannot activate a Sprint sim on a Sprint phone and then move to the v35. My understanding from reading about the open market ULM and AT&T branded v35 is that Sprint maintains an IMEI whitelist. Sprint only allows Sprint branded phones on their network. This is why the ULM model is preferred for Google FI.
Please post what you learn so others can benefit.
