[Q] Unlock code for SPH-L720 - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Hello guys, is there any way I could unlock my Galaxy S IV to use internationally, other than calling to sprint getting the unlock code, because Ive already tried that and the phone has to be active at least 90 days...Please let me know if there are any other ways. I tried to search the forum first but could not find my answer. Thanks...

If you really think about this question alot, I would say that no one has really given them a definitive answer. Now that I have helped you out with your question probably you can help these people with an answer to their woes.

It really has. Just people are tired of saying NO. So the questions either get danced around of ignored. If people want to use a phone internationally, they should have gotten a GSM phone. There is a reason why CDMA phones are cheaper, especially Sprint. They only work here without any hassle. And that's never going to change. End of story.

Still......... that answer is inaccurate and condescending. Forums here are to help , just as you took the time to post........ could it have been more positive than negative? Anyway to answer the OP................ SPH-l720 is indeed a CDMA device which has a UICC/ SIM port. This port, when using the phone in CDMA mode Sprint's UICC (sim card) activates the LTE side of things. However if you can get Sprint to release the UICC card and unlock the port for GSM use, then guess what? You have a GSM abled phone that can switch back to CDMA, which in my opinion makes the SPH-L720 and the SCH-i545 trully a World phone or viable international mobile. So that takes care of that bit, the phone IS capable of GSM.
What if I am already out of the country??? You can still get it activated via Sprint international...... but this is not why you are on XDA looking for a solution. The reason why you are here is for some reason Sprint will not activate the GSM function or even calling them will not make a difference and you are looking for a software solution. Well as of the date of this post, 7/5/2013, there is none. Not to say that it will not happen but there are very few with unlocked versions of this phone to supply data needed. Usually when people get their phone's unlocked there is no need to add to the online database anymore. So have faith and patience, and I hope this helps someone and in turn someone can help me.

I have to strongly disagree with you on that because:
You most definitely can use the phone internationally, albeit while paying Sprint's outrageous international roaming rates (though of course they are not the only ones who overcharge for this functionality, all carriers charge an arm and a leg for international roaming).
Sprint will unlock the phone for contracted subscribers who wish to use the phone internationally but want to avoid paying Sprint's roaming rates.
Beyond these two items, I don't see what obligation Sprint has as far as international capability on the device towards folks who are not their subscribers. I personally don't think they have any. If those folks want GSM capability, then they shouldn't buy a Sprint branded unit.
As for the other "how many of these threads are we going to have" issue... Well, I second that sentiment! What bothers me is that people are too lazy to do a search, instead opening a new thread on this question. I almost wish any time a mod sees a question like this, answer with "answered over and over before, please do a search" and lock the thread.

Nope. Sorry. When you sell subsidized phones and people take advantage of that and skip out on the contract, you have to cover your ass, hence the 90 day wait to establish a good pattern. I got mine unlocked in 30 days, but I've been a 20 line customer for 15+ years.
If you tried to get an intl phone on the cheap, then shame on you for not doing enough research. I would bet Verizon S4 a more expensive because they do come unlocked because of some fcc reg on the bandwidth their frequencies.
If your goal was to just use it internationally only, then you should very sucked it up and bought a gsm only phone. The Dubai guy never having stepped foot in the US should have purchased more wisely.

Yep. I'm a Sprint customer and I Live in the USA. I called them and they did it for me. They said press the UICC Unlock button now and it will be done. That's it. I am baffled as to why people bought a Licked CDMA Sprint phone for international GSM use permanently just because it has GSM capabilities. They just don't understand USA carriers I guess. Lol.

Another bad news for Sprint users and ...

another reason to believe that Sprint GN2 may not have SIM slot.
We already know that previously Sprint Photon Q (made by Motorola) have SIM internally and unremovable. Now we know that there is another Sprint device Optimus G (made by LG) that will have the exactly similar design as far as SIM slot goes. (source here)
With the previous picture purposely a leak of Sprint GN2 device showing no SIM slot, this is likely to be a Sprint own evil doing.
And BTW I'm one very pissed about this. I 'll definitely sending a snail mail to Sprint Executive Office about how pissed I'm as a consumer regarding turning an international capable device into useless crap once the device come out. I go to Thailand every year or so to visit family member and when I am there I would definitely want to use SIM there because of the local number I can use. With unremovable SIM this is no longer possible. I'm very disappointed.
That's sucks, although I don't go over seas that much.. It would be nice to have. Tell them you Ben kohn bah and your red shirt friends don't approve of this.

It appears that this is the route they are going now. I wonder why that is? Does using the embedded SIM force you to use a Sprint International plan, for out of country use?
pardon my ignorance, but isn't the "international" version GSM...and sprint's, obviously gonna be CDMA? and as such, no SIM card?
---at least i've always assumed that SIM cards is something GSM phones use, while CDMA phones do not.

You're right, but some CDMA phones have radios that support at least EDGE on GSM so you can still text and make phone calls overseas (and if you unlock, you could run them on Tmo and AT&T).
However, the question is if the radios will even support the EDGE GSM bands... probably not though.

All of Verizon's LTE phones have a SIM card slot and all of their recent phones also have GSM/HSPA radios for global roaming. I believe some can even run on T-Mobile and ATT's frequencies if you are lucky. But LTE will be Verizon only.
would it be possible to flash a Verizon Note 2 to Sprint in order to have one with a SIM card?
There are so much of competition in market, they skipping features users can easily find alternative. Bad for users but too bad for manufactures. They should understand
Not sure if you saw, but someone has figured out how to remove the embedded SIM in the Photon Q and replace it.
http://forum.xda-developers.com/showthread.php?p=32593285#post32593285
Yea, but whose brave soul gonna do that on not even a month old GN2. And that's beside the point. Seriously, to me it seem like it would cost the manufacturor even more to make the SIM embeded than regular one.

my guess Is That and it decreases fraud. I.e. new accounts created simply to obtain discounted phones that can be used overseas ...then the accounts go bad

I mean how many sprint phones even support GSM EDGE bands?
I don't use Sprint, so I don't know for a fact, but don't their phones usually only run on CDMA (I've only ever heard of Verizon CDMA "world-phones")
I know that the old Touch Pro 2(wm6) and Photon 4G both have dual GSM/CDMA chip in them and they both have SIM slot.
whats the significance in not having a sim card cause it seems like a good thing to me. unless its like tmobile and att network where you can get gsm phones
The significant isn't about whether it have SIM or not. I mean for most people in the US I think we can get by w/o it. I mean it's like once every year or two that people would go outside the country and can make use of it. So it wouldn't be like a final decision whether to get one w/ or w/o SIM. And you are right there are also AT&T and T-mobile. But I can say the for some people it's about the network in their local, while for other it may simply be about not going back to the service they have bad experience with. To me it's about cost, since I'm a Sprint SERO Premium account owner. But very, it's more about why walking the low path? The phone would have been technically capable of it, the chipset, modem, antana support it. This is more about why purposely redesign it to lock it down to a specific network, greed, basically.

Yes, the Sprint HTC Touch Pro 2 most certainly had a SIM card slot. I had a few of them before making the jump to android with my EVO 4G. It was a nice feature to have on a "Business" phone, which is what the TP2 was geared towards. The productivity of the Note 2 also can be geared for Business users, a SIM slot would be of great use.
Ohh okk that makes sense. Cause I never go out of the country so its not that big of a deal for me. But I guess I'd you travel a lot it would be better to have one

Apparently Verizon figured out how to do it properly as they previously have had CDMA, but now allow removable SIM cards for their LTE world-phones. Sprint is now the only provider that locks their phones down like this- it's very frustrating. I am paying for a brand new device that is inherently compatible as a world-phone, but I must buy a separate device to use over seas so that I don't get raped with Sprint's international calling/data plans. RIDICULOUS! These kind of tactics are out of the apple playbook- limit the options of your customers, so you can squeeze em.

[q] unlock code for samsung phones

You can call Sprint and have the SIM card officially unlocked. If you are a new customer you have to wait 90 days before they let you do this though, if you're an old customer it shouldn't be a problem.

From what I understand Sprint has to do something on their end to unlock the SIM. It will only work on overseas networks too, they aren't unlocking it for domestic networks.

Sorry, I didn't know about the Blackberry. Maybe because Blackbaerrys are somewhat unusual devices they made an exception. In any case, that would make it the only Sprint GSM device that I have ever heard of that was capable of operating in the US. All iOS and Androids have always been blocked for usage in the US. That said though, there have been hacks to some of them which enabled US use, though sometimes at the expense of not being able to use the device with CDMA while the hack was in place (meaning they couldn't be used on Sprint).
Hello, guys.
Who looking to unlock own Samsung S4 Sprint - please send to me PM. I have one way which shall to be checked. I'm still don't havemy own Sprint's S4 on hands to check if this way will works

Yep... it was a fruitless venture.
it would be great if we could get the sim unlocked for domestic use.
I'd be happy with unlocking it for non US GSM providers at the moment, I find it ridicules that I have to wait 90 days after having the account with Sprint for 2 years. It is a new phone and I need to travel now.
Anyways if there is any way to unlock it I'd like to know.

[Q] Possible to Unlock?

Hi I wanted to buy this pone from amazon, but the thing is that I would buy the sprint versiĆ³n 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

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.

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.

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] Domestic Unlock of Sprint G2

I broke my sprint phone, but I can upgrade to a new phone now on Sprint. I want to use the Sprint One Up Plan for a bit, then leave the contract since I don't believe it has a contract. I plan on using the G2 as my replacement. I want to move to T-Mobile later, and I know the G2 can be used on Sprint. I also have read here that the G2 comes factory locked by Sprint, and Sprint will one unlock it for international use. Is there something that I could flash to the G2 to allow me to use it on T-Mobile when I switch?
Basically, how can I use domestic USA GSM on a Sprint LG G2?
I will at least root and unlock the phone internationally first anyway, since I need to use outside of the country. Flashing ROMs and things like that is not a problem for me.

Is it possible, after I finish with Sprint, I could flash the firmware and modem of T-Mobile's G2?
Would any of those unlock codes for the IMEI work, since it supports GSM?
Thats risky due to the fact that tmo uses different bands than sprint plus the radio waves are different and sprint is gsm and tmo is cdma

Sprint is CDMA and T-Mobile is GSM...
Anyway, I know the G2 supports all of the bands, so I don't see why this can't happen. Sprint has just locked away the domestic GSM capabilities. Why is flashing theT-Mobile modem such a risk then? WOuld I be able to flash it back?

Sorry always get that bavkwards the issue is with two things the radio, which you said you could flash the modem no problem. Then the biggest issue is the sim card now im not sure if the sprint variant has a sim card slot. But from what my buddy has told me who is a tmobile phone tech they dont have away to enable your service with out the sim card. For some reason they dont do their services like most carriers and just use the phones imei number to set service. If im wrong im sorry and hopefully you can get everything switched. And thank you for the imformation i did not know the g2 has all bands hidden inside the phone. I was just worried that the radio bands would get you. And to answer your question yes you can always just flash them back.

No problem. If I helped give me my first thank you. I'm going to go to the Sprint Store soon and see what they say. The Nexus 5 seems to be compatible with any carrier, but I like the G2 just a bit better. Sprint has a help topic regarding replacing the SIM , so that is not an issue. Hopefully someone else can tell me if the G2 can have a different modem flashed.
I don't want to take any unneccessary risks flashing, because that is what broke my last two Sprint phones lol.

Ok so i was wrong it looks like the spring g2 does have a sim spot so all you have to do is 1 get unlock.from sprint 2 flash required firmware and modem and radio files 3 go tothe phones dailer and dail*#*#4636#*#*. This will bring up the menu shown inscreen shot. Switch your current band from evdo to what is shown in the screen shot and bam sprint branded tmo phone if i help at all pls return the favor with the thanks.

So where do I get the files? And can you confirm this has a good chance of succeeding?
It will not work.. Sprint doesn't unlock the phone for domestic US GSM carriers and the 2 models for Sprint and T-Mobile are completely different. You flash anything like the radios and you'll have a massive brick. If you want to move between carriers, get the Nexus 5.

You will not get domestic GSM service with Sprint atm. Hang it up until a solution if any will come. Even after that, it will never be fully compatible with Tmob bands. I love/hate Verizon.

T-Mobile Nexus 6 works on all carriers CONFIRMED

Hey guys,
I just purchased a nexus 6 from t-mobile and popped in a sim from att, sprint, and Verizon. I can confirm all 3 worked flawlessly with no problems.
At the device start up, i did skip the part where it tried to activate on the network the sim was from.

Unless something has changed with CDMA technology, the Verizon phones shouldn't be able to use data while on an active call. I know they are working to get that working with some new LTE standard but I haven't heard anything about it being here yet.

I'm considering switching to TMo anyway, so I picked up 30 days of pre-paid with the phone for 45$. I plan to try both carriers on my commute, see how signal is on both carriers on the train ride, downtown at work, etc. before making up my mind, and this device makes it as easy as swapping the SIM out!
The issue I had, was I didn't have a nano-SIM. Verizon rep at the store told me there was nothing they could do... I told them if he got me a nano-SIM, that customer support could active it... He gave me a SIM and let me use their phone to call Support to activate it. The support person did a "SIM swap" for my existing device, even though my Note3 obviously doesn't use a nano-SIM.. but that's all it took to activate the nano-SIM, and it works perfectly.
I may be misunderstanding your question... I believe the confusion is that you don't actually activate the phone... you activate the SIM IN the device. You should be able to take the phone out of the box, and drop in an already activated SIM and all will work fine...

I know it works. My question is. Would Verizon block the imei or device I.d.s later down the road to where it doesn't work and only the imei that's been sold on Google play works.

Lol. Yea that's what I was worried about. I didn't want to buy it then down the road oh yea this I.d. doesn't work anymore.
I did not register my device on T-Mobile at all. Just popped the other sims in.
What I'm told is that carriers only care about imei when activating for the first time. If you just put your own sim in there they just can't see the device type which really doesn't matter unless you're looking to call them for support.
T mobile store gave me **** about buying the phone out right. I had to get a friend to add me as an authorized user on his account to buy the phone OUTRIGHT. So stupid...
Also, at T-Mobile the phone out right was 649 where everyone else is like 50 or 40 bucks more which was also sweet.
I also did not get bloat Ware on the phone from the carriers.
The devices CDMA identifier (MEID??) needs to be in the carriers whitelist so if the OP didn't place a voice call over either the Sprint or Verizon networks itnis not "safe" to to say it works on all carriers.
This is supposed to be one model for all of the US with 4 SKUs for the variations, and it should work but there is still the question of whether the CDMA carrier. Allows the phone on their network.

I can confirm I've activated my nexus bought directly from moto on both sprint and T-Mobile. Both voice and data worked with each carrier. Sprint takes a little more when than just putting the Sim in. They need to activate the MEID in their system. You can't just put an active Sim from another phone in and have it work.
Interesting..
Other users have reported the exact opposite.

Buying from T-Mo living in a non-T-Mo area
Yes. I must be one of the only people on here in the U.S. not living in a T-Mo area.
I just ordered from T-Mo (64GB MB). After much conversation and clarification, I've learned that one can buy a Nexus 6 from them outright, which requires also buying a $10 SIM activation kit. Since I do not live in a T-Mo area, I will have to call and cancel my 'yet-to-be-activated' plan, which also required a $50 deposit. By utilizing T-Mo's "buyer's remorse", I will be able to keep the phone, since I bought it outright, but will be refunded my $50 deposit for the service, without ever having to activate it on T-Mo's network. From there, I will pop in my AT&T SIM card, and be on my way! The only thing I'll be out is the $10 SIM activation kit.
Also, the rep's did acknowledge that the Nexus 6 is one of the few phones they have that are already unlocked.
Please do critique this if you foresee any problems I'll have popping in my AT&T SIM and using my existing service with them.
EDIT: Yargh. T-Mo had zero 64GB phones, and have since called me back to tell me they are on back order. But hey... at least I have an order in now. Beats what I've accomplished so far on the Play store all to hell.

This is incorrect, it has been working for 3 years now. Data while on a phone call has been working since LTE came out. It worked on my Note 2, Note 3, and currently works on my Galaxy S5. Also works on my families HTC M7 and M8.
However, it no longer works on the Droid Turbo, and now I believe the N6.
But the original assumption was incorrect, data + voice has been working for years. They did something now that it is not working on new devices coming out.
