I didn't think the Exynos version supported USA LTE? Expansys also says is has an Exynos processor and a Qualcomm chip? Can anyone clarify this phone? I am interested in purchasing it, I just want to know if supports AT&T LTE?
Which phone do you guys recommend for AT&T? Returned my AT&T S5 today after coming to the conclusion that $700 isn't worth it for a carrier locked down phone.
Qualcomm chips would support US LTE bands.
Stick to Qualcomm version.

the one you want is a tmobile phone. G900T. it will work with ATT LTE, doesn't have a locked bootloader.
the problem is if you walk into a Tmobile store and buy one, they will make you wait 40 days before they give you the unlock code.
you could buy the sim unlock at swiftunlock, but now you are up over $800 for the phone; Tmo wants $690 plus this and that, and tax = $765. Plus $25 to unlock = $790.
$800 was to much for me to pull the trigger.
But you can then have an unlocked, flashable, LTE capable phone.
The last thing you might need would be region away from @Chainfire if you intend to travel abroad and use local sim cards upon arrival.
This last step is the one I'm waiting on; the region away. not sure if we'll see it. i hate to be a bother and ask.. i think he said he was on vacation for a month or something

Appreciate your input. I'm actually considering just switching to T-Mobile. The galaxy phones play much more nicely with their service compared to iPhones. AT&T's system switched me off my grandfathered data plan yesterday, so I'm not exactly liking them at the moment.
Hi guys,
I live in New York and I'm using Cricket wireless services (they are using AT&T's antennas),
I want to buy the s7 edge but its lock for the "big" carriers: verizon, at&t and sprint.
Is there any way that I can buy the phone unlocked from somewhere, or buy the phone from one of the carriers and unlock it so I can use it with Cricket?
Thank you!
You can buy it from AT&T or T-Mobile and unlock it we can confirm that as we've unlocked many for customers to use on other networks
but if you want to just buy it unlocked maybe check online you can buy a factory unlocked version online or at the samsung store

Thank you, how do I unlock it if I buy it from them?
Do I have to pay through one of those unlocking websites?

I bought a LOCKED Sprint S7 Edge on eBay (they don't blacklist locked devices)...... I paid $6 thru eBay remote unlock service and the device has worked like a charm for three past 8-9 months.
Unlocked on eBay are usually a little cheaper.... if sellers account/device is paid up then all you'll need to do is put in new carrier SIM to unlock. (Mine wouldn't work so I ordered that remote unlocking service.... guy was amazingly fast, professional and very helpful.
Good luck!
Hi guys.. So I bought a Samsung Galaxy S8 from Best Buy Mobile last month. I had to use sprint because at&t (my fav. carrier) would not finance me on the phone. I was told if I paid off the phone I could switch carriers. So that's what I did. Sprint even unlocked it. Now people are telling me I can't use this certain phone on at&t, or even verizon because it is a cdma phone. No one told me this when buying the phone.
Is it true that I am stuck with sprint?! I have horrible coverage in my area and I can't even use the internet and such unless I'm on a wireless connection. What can I do? Please help!
Did you try putting in a non sprint sim?
If it is SIM unlocked, just flash the unlocked (G950U1) firmware on it.

If the Sprint unlocked your phone, then it won't hurt inserting another sim in it. Theoretically speaking it should work and if it won't, then flashing is another way of making it work.

Who are these ignorant people telling you this and why are you listening to them?
1) Verizon also uses CDMA, so having CDMA is the reason it WOULD work with Verizon.
2) All the carriers in the U.S. get the same phone. All the bands needed for a specific carrier are activated when the SIM card is installed. The only reason it wouldn't work is if Sprint had not unlocked the phone after you paid it off. It would be locked to Sprint to prevent you from not honoring the purchase agreement. And even then it would be blacklisted on Sprint network, if you didn't honor the purchase agreement.
3) if inserting the SIM card for another carrier doesn't automatically change the firmware, then do what this guy said:

Sprint, at&t and even verizon said my phone wasn't compatible even after I told them sprint unlocked it. I had no idea about all this cdma, gsm crap when buying the phone. I have never had a decent phone like an S8. All my phones have been cheap prepaid phones since now due to the fact no one would ever finance me for one. I was SOO freakin surprised and happy when someone actually agreed to finance me, I figured I could pay off the phone and then switch. After paying off the phone is when these companies said it was incompatible. Weird thing is I went to IMEI.info and it says it IS compatible and IS unlocked for sure. I then went to at&t online and after typing in my imei number it also said it was compatible. I'm so confused. I am going to take it up to at&t tomorrow and see what happens when I buy and insert a sim card. If it turns out to be sim locked is there a way to bypass this? I truly have paid the phone off and after doing so I asked sprint (on the phone) to sim unlock it, they said they did.
Please do not listen to the idiots at the mobile companies. There is ZERO difference in the S8, ZERO!!!!! If It's not sim locked it will work on ALL carriers, both cdma and gsm.
If It's still sim locked, some people have had success paying a third party to provide a code. But I would try sprint first since They said it should be unlocked.
My guess is that it will work fine with another sim card.
I would either flash the att firmware or the unlocked firmware on it.

Should I flash the att firmware before inserting the sim or only if the sim does not work? Also is there a way and should I back up my sprint firmware or should I be ok? Thanks.

I would flash the unlocked firmware on the phone. Will get rid of bloatware. No reason to backup sprint firmware, Its everywhere.

It says this guide is only for snapdragon S8's I have an exynos S8. Is there another guide for that one? Nevermind, IMEI.info said I has an exynos, I guess it was wrong info. CPU-Z says it's a snapdragon 835. I'm assuming the CPU-Z info is the correct info?

You said you purchased that phone from Sprint directly. It's a snapdragon. Exynos is in the international version, which Sprint does not sell.

If you bought it from Sprint (or even just used it on Sprint), then you have a Snapdragon 835 S8. Only the Snapdragon variants have CDMA bands for Sprint and Verizon. Only the Snapdragon S8/S8+ variants are sold by carriers in North America -- so they can be cross compatible with Sprint/Verizon/AT&T/T-mobile/Canadian carriers. That's why whoever told you this nonsense is so ignorant.
If you had IMPORTED an Exynos variant from like England, then you would be limited to AT&T or T-mobile. But you have the "universal" Snapdragon model. Now the Exynos variant has an easily unlocked bootloader, which is a reason people import them, but that's another topic altogether.
As long as your Snapdragon 835 S8 is SIM unlocked (you have paid for it in full, and Sprint says they have unlocked it), you can take it to any other carrier or even an MVNO (like Straight Talk) and use it.

If you used it on Sprint, you have Snapdragon 835. Only the Snapdragon S8/S8+ variants have CDMA bands for Sprint and Verizon, in addition to LTE bands.

Since you phone is paid off, when you go to AT&T, try AT&T Prepaid (formerly called GoPhone). It's really for people who already own their phones.
Same high speed data off the same low-lag data servers used by "contract"/postpaid AT&T customers (with one exception, which I'll warn you about),
same in-store AT&T customer service as contract/postpaid AT&T customers,
same AT&T SIM card as contract/pospaid service. (The store may have SIM cards labelled "AT&T Prepaid", but underneath it's the same AT&T SIM card. If they try to charge you for one, tell them you want the FREE AT&T SIM card. It's the exact same thing.)
Make sure you go to an AT&T corporate store, not a "franchise" store. At the AT&T corporate store they will even give you free AT&T SIM card to use for AT&T Prepaid. (Franchise stores will try to sell you SIM cards.)
The advantage is AT&T Prepaid is much less expensive service than "postpaid" AT&T (contract service). Since you already own your phone in full, all you need to pay for is monthly service. You don't need to pay extra each month so you can get a "free" upgrade to a new phone in 2 or 3 years. (Not free, you are really paying for it with extra fees each month.)
You would want the $45/6GB plan on AT&T Prepaid. Do not fall for the $60 "unlimited" plan. The $45/6GB plan gives you plenty of UNCAPPED high speed data/unlimited calls/unlimited texts. Whereas the $60 plan caps your data speeds at 3mbps to compensate for it being "unlimited". AT&T Prepaid uses same data servers as their AT&T postpaid customers and I get ping speeds often less than 30ms, most often 26-29ms, which is fantastic low lag speed. (Lower pings are better, lower ping speed = less lag). If you go to even a service like Cricket (owned by AT&T, but you won't see any AT&T logos anywhere), they use proxy server farms and you often get triple digit ping speeds (high lag). This is also why Cricket has to use a DIFFERENT SIM card from regular AT&T. Higher ping speeds make it seems like your download speeds are much slower than they are.. due to LAG. Plus Cricket caps ALL download speeds at 8mbps. Until AT&T Prepaid (formerly called GoPhone) introduced their $60 "unlimited" plan, ALL their plans were uncapped high speed data. They didn't cap download speed at all. But now they have started capping speeds with the $60 "unlimited" plan. So STAY AWAY FROM THAT.
With the $45/6GB plan, if you autopay each month, you can save $5 and only pay $40 per month. So, $40 per month for 6GB data, with UNCAPPED low lag data straight from AT&T. Don't let them charge you for a SIM card! AT&T Prepaid uses the exact same SIM card as "regular' AT&T.
If you decide you don't like it, for whatever reason, you can switch to "regular" postpaid AT&T. But since I always pay for our phones in full, I like to save on monthly service. Although there are tons of MNVOs with prepaid service, they all use proxy servers with high lag (high ping speeds). Even AT&T's own Cricket is configured as an MVNO, to compete with MNVOs like Straight Talk. But AT&T Prepaid is not. It's "pure" AT&T, but at budget prices -- which AT&T uses to compete with actual carriers like T-mobile and Sprint.
You can "bring your own phone" , which in this case is your fully paid for Galaxy S8.
How do I know which ones are the corporate stores and which are the franchise stores? I'm looking at the St. Louis map now. Some say at&t authorized retailer and then some just say at&t.
I have a sprint model and I unlocked it.
It works with T-Mobile and gets LTE
It works with att and gets LTE
It works with Verizon my current carrier now and also gets LTE
Highly recommend flashing the unlocked software if you go this route the sprint software with non sprint SIM cards is very annoying.

It worked! Thank GOD! In my room now I get -90/-100 with att and had -100/-125 with sprint. It is using HSPA and I can't find LTE on here to switch over. It stays on 3g, it never goes to 4g or LTE, how can I fix that?
So please tell me what I need to do to delete the sprint crap on here and put att on it. Thanks guys.
Not being rude, but you've been told many times on here What to do , reread the posts.
Follow the directions, we can't spoon feed every little thing.

Ok, so I want to do the prerequisites - check.
Then just do the carrier switching part and I'm done right?
Do I do all this with the sim card installed or not installed?
Sorry, this is my first time doing this.
Ok, I did what the guide said. During the flashing standard firmware part after clicking start is said FAIL! SHA256 is invalid. I ended up going back into ADB, rebooting and trying a different att firmware download and now the phone works. Weird thing is, I don't see alot of the apps that I had on an old phone with go phone and 4g LTE is not working, it's not even an option. What should I do if I want to wipe clean the phone to stock samsung android, not stock sprint as I bought it. Then I could insert the new go phone sim and it will install those apps and turn on 4g LTE? I'm learning guys, slowly but surely. I love this kinda stuff, so please bear with me here.

Authorized retailers are code for "franchise stores". They are not owned by AT&T nor run by AT&T. They do not have actual AT&T employees and they will nickel and dime you for every little item, like SIM cards. Whereas "corporate" AT&T stores will give you free AT&T SIM cards.
When AT&T Prepaid was called GoPhone, event the AT&T stores sold a GoPhone SIM card "kit" that had various sizes SIM cards with plastic shims for $15 -- which was totally unnecessary. I just told them, "NO, I want a FREE AT&T SIM card which fits my phone." And at the corporate stores they have to give it to you. AT&T and AT&T Prepaid (formerly branded as GoPhone) uses the EXACT same SIM cards. It's just they had some "labelled" as GoPhone but underneath it was the exact same thing.
3or 4 years ago, I had a friend buy a brand new Samsung Galaxy phone "on contract" INSIDE an AT&T corporate store, then immediately paid it off with his credit card, and switched to GoPhone -- all in the same visit -- and they did NOT even touch his AT&T SIM card inside his phone. It's just an internal AT&T accounting change. Now GoPhone has been re-branded as AT&T Prepaid to make it less confusing.
