So I am going to buy a probably used Galaxy S5, most likely from Swappa.com and I am going to activate it with Metro PCS, which is a GSM carrier, so I know I need a GSM carrier GS5, like from AT&T or T-Mobile. I did a bit of googling and I only ended up with more questions... Are the AT&T and T Mobile versions of the GS5 carrier locked? From what I read online, the ATT is locked and the Tmobile is unlocked, but I cant be certain from the couple forum posts I could only find. If the phone is already unlocked, I can just bring it into the Metro PCS store and activate it, right?
Now, what if it is locked? Can I carrier unlock it myself? How do I do that? Do I really need to buy an unlock code online? Seems kinda sketchy to buy these codes from random unlocking sites, but if I have to...? Also, can I have it unlocked by Metro PCS or T-Mobile or ATT?
Next part of my question is about the bootloader. Again, I did some research, but found only one relatively... relevant forum post. So I come here for direct help. I was chatting with AT&T tech support on their site asking about the bootloader.
Anyways, ATT told me the bootloader on their GS5's are encrypted locked. What about TMobiles version? Supposedly if they are encrypted, there is near to no chance of really getting that unlocked. Although, if they are not encrypted, would they be able to be unlocked? I have no idea about T-Mobile having a locked bootloader or not.
Lastly, has the bootlader been unlocked already for any GS5? I ask because ive seen some GS5's with custom ROM's and launchers and stuff, but last I heard, they were still locked.
You didn't do much "research" via Google or searching this forum or you'd already have the answers your are looking for. These questions have been asked and answered innumerable times.
Very few carriers other than ATT and Verizon lock bootloaders. TMB's bootloader is not locked. Generally speaking, TMB model has the most GSM bands and is arguably the most desirable model but you need to check whether those include the bands you need with the carrier you plan to use. Do that by checking and comparing the bands that both carriers use or simply find out what S5 model your carrier uses itself.
Most phones, incuding TMB, ATT, et al are SIM locked. But you can easily get a third party vendor to provide an unlock code for about $20 and thereafter use it on another carrier.

Sorry, this is just totally new to me. Ive never had an android device other than a Nexus 7 I was gifted that i hardly use. Ive never even had a smartphone, so Ive had to find and absorb all this info about rooting, bootloaders, unlocking. Its been kinda mind boggling. So in the meantime after I posted this I pieced together this info.. I hope I am corrrect:
-AT&T and Verizon have been locking their bootloaders for a while and everyone hates them for that
-Any GSM carrier phone can be unlocked to work with any other GSM carrier
-CDMA cannot be unlocked at all
Kinda iffy on this one, not 100% sure... -Rooting is the same as unlocking the bootloader. If the bootloader is not encrypted, the phone can be rooted and custom ROM's/recoveries can be installed.
-Supposedly Verizon and AT&T GS5's can now be rooted... (cant link to outisde links, but just search "How to Root ANY Samsung Galaxy S5 Variant (Even AT&T & Verizon) in 20 Seconds Flat" and its the first link.
Based off this new info I have gathered... I want a T-Mobile GS5 (or AT&T if they can in fact be rooted and have custom ROM's installed on them). I will have to carrier unlock it myself unless it is already unlocked (someone on Swappa.com says they are selling a "factory unlocked" T-Mobile GS5 for $480, so I guess T-Mobile also sells carrier unlocked versions). I will unlock it using a code from theunlockingcompany website for $40 (seems like a steep price, but supposedly its the best site to use). I will then unlock it with the code which should take a couple minutes after I get the code, code taking up to 5 hours to arrive in my email. I will then have to take it in store to Metro PCS (hopefully I can do it online too if I order the SIM card online to ship to me for $10) to have it activated with them and get service. Then it should be activated, have my phone number, have cell and data service, paid/pay $40 a month. All is well in the world.
Is that info I discovered above true, what about the steps I should go through in the last section, above?

I wouldn't know where to begin. Yes, a TMB phone is ideal IMO for ATT because it covers all of the ATT frequencies and then some, plus has an unlocked bootloader. Most of the rest you have wrong.
Any GSM carrier phone can be unlocked to work with any other GSM carrier
No. You can unlock phones, but models will seldom work well on a different carriers frequency allotment.
CDMA cannot be unlocked at all
Not true.
Rooting is the same as unlocking the bootloader.
They are not the same thing.
If the bootloader is not encrypted, the phone can be rooted
Not correct. You can root phones with locked (encrypted) bootloaders.
Supposedly Verizon and AT&T GS5's can now be rooted
Almost any Android with a pre-June6th firmware build can be rooted.
so I guess T-Mobile also sells carrier unlocked versions
Nope.
I don't know how you managed to adopt so much misinformation. I can only assume that you haven't done much reading yet and /or made a lot of assumptions. You should read some of the sticky posts to get a better general understanding of how everything fits together. Then you can pose more informed questions.
It has nothing to do with being new to smartphones. You just thought that it was easier to ask than to do a proper search or puzzle out a few confusing points. It would be in your own best interests to do some reading, but whether you do or not is entirely up to you.

I am a Verizon customer that wants a current-gen bootloader-unlocked phone. Enter the US996. It retails for $800, but there are some eBay auctions that are selling them for much less (used in excellent/mint condition). However, the auctions say that they can ONLY be used on US Cellular service. I asked one seller what the deal was, and this is the response I got:
Thank you for your question. We are not selling the phone as compatible with other carriers or carrier-unlocked. We can't guarantee that the phone will work with an another carrier. We are only saying the phone will work with the carrier US Cellular. We can only guarantee that it works with US Cellular.

It sounds like they're just playing it safe, since they are a US Cellular authorized reseller, and they don't want to take on the responsibility (or policy ramifications) of selling a device that's advertised to work on other carriers. You know... maybe they're not allowed to sell phones that are advertised to work on anything other than USC.
I asked this question in another thread, and at least 1 user thought they had heard that there are US996s out there that are locked to a carrier. This doesn't make sense to me, because the model numbers should reflect conclusively what the capabilities are, and LG would have no reason to muddy those waters. I can, however, conceive that US Cellular could buy a bulk of US996 phones, and flash a sim lock on them somehow. Perhaps because LG didn't have a SKU for USC set aside. Or perhaps there's a process that, once a USC SIM is used on the phone, it's locked to USC until some subsequent unlock procedure is carried out. (Similar to unlocking a carrier-locked phone for use on another carrier) I don't know, this is all speculation.
So... what is the consensus? Who here is using a US996 on Verizon? Any chance you got it advertised as a US Cellular-only device and it ended up working? Was it an easy process? (ask me about my failed attempt to activate a USC Note 4 - beyond the scope of this thread, but it gives me some contextual knowledge on this topic) I know there are other threads about using the US996 on Verizon, but I'm asking specifically about the possibility that USC has somehow locked them to their service, and in spite of the model number matching the "unlocked version" I wouldn't be able to use it on Verizon.
Thanks for your time at attention.

Although it doesn't seem to make much sense, there are in fact 2 us996 versions. One is the unlocked US version and the other is locked to us cellular. From what I've read they are not interchangeable.
The 996 unlocked is the one that also has the official lg unlockable bootloader.
No idea why they gave 2 different phones the same number but from everything I've read since the phones came out... They did exactly that.

Ha… the only way I can fathom that this happened is that verizon got their own CDMA model number that is denied bootloader unlock, and US Cellular sim-locks the other CDMA-capable model themselves. Maybe there's a monetary cost that USC didnt want to assume associated with having an exclusive model number provided from LG.
In any case… I won't spend much more time pontificating on it if there's no way to use the USC version on Verizon.
Thanks for the response.

I can't say definitively that you can't use it on another network... Only that there's definitely 2 different versions with the same number.
Hopefully someone with more knowledge than me can give some input on that subject...

So V20 US Cellular it's already unlocked?
Hello everyone,
I am looking to upgrade from my S4 to an S7 over the next few days, and I have been trying to decide which is the better option between the Verizon model and the unlocked model. I will be using this phone on a Verizon network for now, and was leaning to the unlocked model to get rid of the Verizon bloatware. There is a chance I will be living in a different country in another year or so, so I figured the unlocked model would also give me more flexibility with my next carrier, as I had heard the Verizon model does not support all carrier frequencies. Are there any distinct advantages to going with the Verizon model over the unlocked model, or are there any other important differences I'm overlooking between these two options?
Thanks!
Unlocked how? Boot loader unlocked or carrier network (SIMM) unlocked? Verizon phones are carrier unlocked. Meaning, you can already take an AT&T SIMM and put it into the Verizon S7 and it will work.
As for removing verizon bloatware, that's only possible if you root. Unlocked is specific to the carrier only, not an unlocked bootloader. None have an unlocked bootloader that I know of.
The carrier unlocked phones also receive updates much slower than the normal ones.
https://plus.google.com/+DroidLife/posts/ENv2fH9zD7e
If you want carrier unlocked phones that get updates faster than the generic carrier unlocked phones, get the Verizon phone. As per this article, it's already carrier unlocked and it's already updated to Nougat. Might be some hoops to jump through, but it works:
http://www.androidcentral.com/yes-verizon-galaxy-s7-and-s7-edge-are-sim-unlocked
The generic unlocked ones are still on Marshmallow and there is no word on if/when they'll get Nougat. Also, the Verizon one is cheaper than the generic carrier unlocked phones. Expecially if you can find a sale going on for it.
There is a hybrid rom that is debloated and works great for all models, it is posted in the vzw amd tmo s7 forums. I'm using it on two phones myself.
The U firmware has no bloat, and has all bands available for use. The main downside is that nougat still isn't out for it, and certain apps won't work if you're from Verizon such as their voicemail app.
On the plus side you get some features that Verizon charges extra for, such as caller ID built in for free.
Regardless you can flash any firmware to any S7 so long as it's the snapdragon variant.

I've been curious about the G-930U also. If you know, please tell me if these working assumptions are correct or not: The "U" has no carrier branding on it and it has no carrier "bloat" in it (although maybe some Samsung stuff). The "U" CANNOT be bootloader unlocked because it has the Snapdragon processor and at present none of the Snapdragon variations can have their bootloaders unlocked (how I hope this isn't true!). The "U" can be flashed to carrier-specific firmware, although I don't know what the advantage would be.
I'm still mostly using an XT1575, the Motorola X Play Edition 2015. It too had no carrier contamination but it's bootloader was easy to unlock. All I had to do to get it to work with Verizon was insert my nano SIM card. Do any phones still work like that?
Hello. I cant seem to find any service that can sim unlock a verizon htc 10. I am looking for a remote unlock, or a way I can be sure it will unlock, since I am buying the phone off Ebay. I would hate to buy it, to see it wont accept unlock codes.
Will converting it to US unlocked version (s-off, change cid, flash ruu) sim unlock it? Or is the sim lock permanent on verizons?

As I mentioned in the other thread the verizon 10 is not sim locked and will work with a gsm sim card, provided that the lte bands used by the GSM network are supported by the Verizon variant. You just need to switch the network mode to Global in Settings I believe.

Thanks for your replies. I have asked the person selling it, and he says his is locked to verizon, it will not accept gsm sim. The unlocked verizons are a bit more expensive. Is there any remote unlocking services for verizon? Even if it has bad ESN.

Regarding your question sorry I don't know. And I suspect the reason you don't find much info is because it's not needed.

Yes, you can ask for an unlock, but you have to meet certain criteria, and some phones being sold dont meet the criteria, or the owner does not feel like calling verizon and asking them to unlock it even when being free. If I buy one I can not ask them to unlock it since I will not be on thier network. I have fallen in that trap before. They ask you have it activated on their network so they can send the unlock. Stupid, but its their rules.

From Verizon's website:
We do not lock most phones or tablets that are activated with our postpay service, either during or after the term of your service contract or*Device Payment Plan*installment sales agreement.
We do not lock our 4G LTE devices, and no code is needed to program them for use with another carrier.
This is their official policy written on their site, so if the seller is trying to sell you phone that's somehow locked you should beware.
AT&T claims to unlock their SIM locked device for US networks only, but not Europe?
Hi people, I'm new in US Samsung models world, so I have a couple of burning questions.
Long story short, my friend lives in US, has bought AT&T S7 Edge last year off contract, paid the device fully, so in theory he should be free from their will, except the device being SIM locked to AT&T. Now he has S8, and wants to send me his S7 Edge here in Europe, however upon contacting them about removing the lock, they have claimed that at least a year has to expire from the day of purchase for the phone to be fully unlocked and used globally, and as for now, they can only unlock the phone from their network so it can be used (on all networks) in US only, but it can't be used in Europe (until a year expires which they indicated).
Now, from my very limited knowledge I smell BS here, since only thing they can do is block the usage of certain bands through their software thus limiting usage of the device across all networks, but that can be avoided by flashing a fresh firmware, or better yet U firmware, since I've read that its Samsungs firmware with unlocked bands for a global use.
So, as long as there is hardware capability, they can't limit it really permanently, or for certain amount off time if you bypass that with U global firmware.
Or am I wrong here? Is unlocking through 3rd party websites better solution?

1) As soon as the phone is paid off (no balance owed) and you have been a customer in good standing for either 2 months (post-paid) or 6 months (pre-paid) you can request a SIM unlock code. Yes, this is BS, but it is what it is. Note that it is important to do SIM unlocking BEFORE removing your old device from your account, as you will guarantee a bad time trying to do it afterward.
2) The SIM unlock is global and should allow any APN to be used with the device. AT&T doesn't really care where you use your unlocked device because T-mobile is just as much not AT&T as any European carrier.
3) If you can get it from AT&T for free, why not? Otherwise, get it where you can. So far, every time I have requested an unlock for an AT&T device I have had to escalate, and for some devices they don't even offer unlocks (AT&T branded hotspots, tablets, etc. aren't unlockable through AT&T)
4) Using U firmware doesn't help because it is the baseband processor (and related firmware) that handles network locking. Simply switching to unlocked software doesn't alter the baseband at all. Changing the modem/baseband firmware won't help EITHER, because that processor has it's own non-volatile storage. Carriers take SIM locking very seriously at a hardware level.

1) All those conditions have been met, so there shouldn't be a problem about requesting SIM unlock code, and they did say the phone can be unlocked and be SIM free but it will work on US networks only, and not on European, until 1 year expires.
2) Since the G935A has GSM 2G bands and HSDPA 3G bands, it is already compatible with European bands, or specifically with bands on my carrier here, I don't see how are they going to unlock it to work on US networks but not on EU, that's what confused me. SIM unlock should be global that is how it goes anyway.
3) Yeah that's what I thought, but since they mention limiting the unlock (if it is possible) for US usage only (maybe tampering with the device in hand) it might be better to go for 3rd party unlock.
4) Thanks for the explanation, that seems serious, not sure why so serious though.
Anyway as a conclusion, since both 2G and 3G bands match with my carrier's, if they do unlock the device (AT&T) it should work in EU, despite their claims that it won't for a year? How would they "unlock" it after a year when the device is not in their hands :S
I suggested to my friend to request a code through 3rd party anyway, unlock it and send me the device, since he was already pissed off with the response from AT&T.
I have a Samsung tablet E that is locked to T-Mobile. How would I be able to unlock it for At&t?
I feel for you as once, years ago, I had to jailbreak an AT&T iPhone to get it to work on T-Mobile, so I know the feeling of wanting to change what the phone can do but which the carriers locked you out of doing.
Hence, I would like to see you get that tablet unlocked where I have been on T-Mobile in the USA for over a decade and they've unlocked EVERY device I ever asked them to unlock for me.
There are a few caveats, of course, which you didn't mention so I have to ask you.
a. Do you own the device (or does T-Mobile still own parts of it in your contract?).
b. Have you been on T-Mobile for more than two billing cycles?
c. Do you owe T-Mobile any money (e.g., unpaid bills)?
Depending on the answer to a,b,c above, did you ASK T-Mobile to unlock it for you yet? If you did ask, what did they say?
In addition, many people have asked T-Mobile for a temporary unlock when they travel from the USA to Europe but it doesn't seem like you want just a temporary unlock.
