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.

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?

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.

Hello all,
I will need some UberGeek advice for this one...lol
I use TING as my MVNO provider. They offer CDMA and GSM networks backboning on Sprint and T-Mobile. I had to get a new phone and ordered a Sprint CDMA version G900P but received a Verizon model G900V. It works perfectly fine on the TING network.
I am just wondering if there is any reason not to get this phone and to go with a T-Mobile model instead? I normally would go Sprint/CDMA but wanted to try out GSM this time. Both have excellent coverage in my area. I also know about the ATT/Verizon bootloader being locked. I have already rooted this and it's running Lollipop just fine a sper the instructions found in threads here.
TING told me the phone is no different essentially and there should be no problems. As always their cust, svc. was excellent and informative. This phone apparently has dual radios...CDMA and GSM. I don't have to worry about warranties, KNOW tripping or Verizon's bs. As I said, I am rooted and running fine. I will either debloat this sucker or go with another ROM. Right now THE only bugaboo I see is that there are so few ROMs for the Verizon model. I am not into switching ROMs. If I ditch a debloated stock setup, it would have to be very something very clean and stable based on Lollipop. Seems like CM 12.1 could be nice but right now slightly risky and they don't have the Fingerprint feature working either.
Does anyone feel it would be smarter to return this and get a T-Mobile model? Any food for thought or advice or "Here is why you'll regret the Verizon model 6 months from now" kind of advice?
Thanks in advance!!!!!!!!
Besides the locked bootloader, the G900V is the same phone as the rest of the S5's (of course with different radios for CDMA). If you're cool with just running stock firmware forever then keep the Verizon model. The T-Mobile model would allow you to do whatever you like with it though, as the bootloader is unlocked. Virtually no possibility of losing root.

Thanks for the response. Pretty much what I figured. I have it rooted and using Safe Strap and MIGHT toy with CM 12.1 since there are many out there with the Verizon model that seem to like it. Plenty of YouTube videos too.
I crushed my S5 (AT&T) today, pretty much broke it in half. Ooops.
I've long disliked the bootloader lock and ATT bloatware but I want to stay with the S5 platform for now since I like the form factor and various features.
Which is the best S5 variant for me to get that allows the most flexibility with unlocked bootloader and loading various ROMs? I'm thinking its the T-mobile variant, but wanted to get some feedback before I bought one. I'll be using a SIM from Puretalk as my carrier, so any SIM unlocked version should work.
Many thanks!
G900F seems to be the most popular, and has an unlocked bootloader

G900T is a good choice as well. If you're in North America it might be easier to get your hands on one of those than a G900F.
I've been combing the forums and I'm still unclear on a few things and looking for help. Current AT&T customer and I plan to switch to T-Mobile soon. Any confirmation or corrections/answers to the questions/statements below would be really appreciated.
1. The 935F variant is the international model that works with all GSM carriers (and I assume without any carrier bloatware) but VoLTE and wifi calling will not work on any GSM carrier here in the US. Theres a secondary 935F model (d?)- whats the advantage there? Shopping tools that let you compare the models show no difference but always priced differently. There is something I'm missing.
2. The 935U variant is official US unlocked model for use with any carrier. Only silver. I have not seen any posts confirming that VoLTE and wifi calling works- and will continue to work if you switch carriers.
3. Lots of listings for factory unlocked 935A variants. Official AT&T version. That just means a reseller has applied unlock codes to each and resells them? I'm very unclear here. Listings always say compatible with all GSM carriers. But will AT&T bloatware, logo continue to survive? And again, will VoLTE and wifi calling work and continue to work if I switch carriers. This is also the cheapest phone to buy virtually new. But if truly GSM compatible with features that are important to me are intact among carriers- what would I get for the significant premium to get the 935U? Besides, I wanted black.
4. Black Pearl- has this been released in the US and in any specific model? I have not seen one.
Thanks in advance. Really appreciate it.
FD is dual sim. You can put 2 GSM simcards there and both are active. Can send and receive sms or calls.

You can install 935U stock firmware on att/tmobile/verizon version. If used on tmobile network, you will get wifi call and volte. For att you have to install or have att stock.

1. 935F is the European / International model. 935FD, D stands for Dual-SIM, both slots will be able to accept a GSM SIM card and are usually used, as one for work, and one as a personal number. Dual-SIM however, is not a popular concept in the US.
2. Check the 935U threads, if a CSC flash is possible, it might work. Though, I'm not sure.
3. Yes, if you have an AT&T phone, it'll still have the AT&T ROM, which will always remain the same, regardless. It will work with other carriers, meaning SMS, Data and calls are compatible, but things like VoLTE and WiFi calling might not work on the carrier that the phone isn't intended for.
4. No it hasn't. It's been released in South Korea with 128GB of internal storage. Also available in the UAE, India and some other Middle Eastern countries. Only in a Dual SIM Configuration (SM-G935FD), and with 128GB of internal storage. It's a limited edition phone, and not sure if it'll be launched in the US.

A couple of followups if thats ok:
1. So if I purchase a "factory unlocked" 935A, before I insert any SIM, I can immediately flash the 935U firmware and it will remain unlocked? I couldn't find a single post that said VoLTE or Wifi calling worked with the 935U firmware on T-mobile (AT&T- what do you have to install?)
2. Flashing to firmware is not considered rooting the device? My work will not let my device connect to the network if it is rooted.
Seems like there is no reason to spend the extra money for the 935U variant. I can save hundreds and purchase an unlocked 935A and flash the firmware. I've rooted devices before and the process looks similar.
Thanks.

According to other people in verizon 935u thread and att 935u thread, volte and wifi call works on tmobile. For att wifi call and volte, it must be a ATT carrier firmware. ATT only let their branded phones have wifi call and volte while tmobile allows any phone to do this. That's why with 935U wifi call and volte will work fine on tmobile.
Every time you insert a new sim the phone will adjust settings, so there's no relation with what you can install.
Flashing is done through Odin while phone is in Download mode. There no root involved.
I see this BOGO offer direct on Samsung's website for Galaxy S8's. In the past, all Galaxy S phones were SM-G920T (T for T-Mobile) SM-G920V (V for Verizon, etc) and then Best Buy sold that piece of crap SIM unlocked SM-G920U that was bootloader LOCKED and couldn't do anything with it.
I'm trying to find out here if the Bootloader is locked on any variant of the Snapdragon 835 S8's, and which version I should get. T-Mobile has the same BOGO offer on the S8 in the form of a rebate as well, but I can't confirm anywhere the specific model number. I'm so jaded by the fact that T-Mobile left the bootloader locked on their S7 that I can't imagine them leaving it unlocked.
The G6 is also BOGO right now as well, but I don't know if that bootloader is unlocked like all my previous LG phones from T-Mo we're.
I'd really appreciate any kind of confirmed answers you might have!
Cheers!

All the carriers have "U" devices in the U.S. this year. The SIM you initialize the phone with is what carrier's features are added. A "U" from Samsung apparently doesn't take on the carrier whose SIM is used features and remains virgin. So "U" could be considered "universal" or "U.S." It's still a S-835 device which means "U" definitely doesn't mean unlocked bootloader.
I'm not an expert at all but I really doubt that ANY Samsung bootloader will ever be unlocked again. Pretty much after 2013 all bootloaders were locked [AFAIK] at least for the Galaxy series. I really like Samsung devices but my Galaxy Tab S (late 2014) isn't even going to get the Nougat upgrade - this actually pisses me off greatly.
When you see 'unlocked' concerning a phone/device it means CARRIER unlocked, not the bootloader. The 'unlocked' means that you can use it with any carrier that the device supports - so just about most of the carriers/providers in the entire world. Still not sure about this concerning CDMA (Verizon/Sprint) as some things may not work (different bands). Tried using GSM phones on CDMA a few years back and wasn't able to use 4G/LTE & also MMS.
Good luck.
EDIT:
Was typing this as BarryH_GEG replied to your question. Yes the letter following the model corresponds to the various carriers (Verizon, Cricket, Sprint, etc) and are also different for international versions.
EDIT2:
On another note I own a Galaxy S7 Edge (international) that has the Exynos processor that is unlocked. At the same time this is the only device I've never rooted because it works so well for me, no carrier bloatware. Also the only device I've ever purchased without a removable battery. Until the latest updates I was able to go 2 days without charging (not anymore unfortunately). The international S8/S8+ also use the Exynos processor so you might consider this option. However the cost will be high as it was for me when I purchased my GS7edge as you'll need to purchase it directly without any US discounts or such. I paid out just over $700 for my GS7edge directly, though at the same time my AT&T bill is much lower because of this.
I've researched the GS8+ international and it's looking to be around $800. Compared to trading in my GS7edge international for an unlocked US version I can get for $375 (with trade-in) if I do this within a month or so... I can probably get $400 for my GS7edge (since it's international) but how long will this take? If I only get $300 for it for a quick sale I'll still spend $500 for the new 8+ so is this worth it?
Only stating these issues so that you understand my thinking concerning an unlocked bootloader. These are [mostly, still SS stuff] bloatware free, have incredible power, etc, etc. I miss rooting my device but is it really worth it for the cost? I really want the international/Exynos S8+ but still not sure.
Let me know your thoughts, later.
