Based on what I read so far, only unlocked version of AT&T will work only with GSM provider. Would like confirmation of this. Thanks!

Optimumind... can you provide any explanation for your answer?
Unless something has changed, Sprint is CDMA, not GSM.

An unlocked AT&T GS8 will work on other GSM networks but not on Sprint b/c Sprint won't add the AT&T GS8 IMEI to their system.

The hardware on all the s8's are the same so technically it will work but the imei isn't white listed so you won't be able to activate it on sprint but the sprint version can be activated on att or any other gsm provider.
Sprint galaxy s8 works with tmobile and verizon

Hey there. I have an S7 Edge unlock from t-mobile running the unlock firmware from G935U. Sprint SIM cards are lock, I have a friend who works for sprint. I have 3 Sprint S8 and S8+, 2 unlock and running on T-Mobile network. I took 1 of the SIM card and put in my Unlock S7 Edge, the phone just keep trying to connect to network and repeating the same process. Didn't work at all, but the Sprint S8's works excellent on T-Mobile network after flashing the UNLOCK firmware.
---------- Post added at 03:01 AM ---------- Previous post was at 02:53 AM ----------
I got 111.71 mbps download, 20 mbps upload speed from my Unlock Sprint S8+ running G955U1 unlock firmware on T-Mobile network. Couldn't ask for anything more than that.
I will provide my non Sprint S8 variant experience.....for any US S8, they all have the same hardware. I have noticed that ATT and TMO models have CDMA hardware, but are turned off in the carriers version of the firmware . Flashing the stock unlocked S8 firmware or the Sprint/VZW FW will enable the phones for use with CDMA and all LTE bands. I had an ATT version sim unlocked and attempted this on Verizon FW with a VZW sim and it worked perfect....but there is a major roadblock with Sprint. Sprint is the only carrier that I have tried that requires an update of the IMEI to the account (ie you cant just pop a sim in and the device works). VZW for example shows Unknown device on the account instead of an S8, but all the services still work. Sprint shows 3G for about 5 minutes, then you get a message that the sim is locked and to reboot or call support (not the same as the phones sim slot being locked, but more that the system cant register the sim/device combo). Sprint stores have the capability of adding IMEI's to the Sprint database, as long as the IMEI does not come back as ineligible. Well, I took the S8 to several stores and none of them could add it to the system. Several employees advised me that the IMEI's from other carrier's are blacklisted so that it can not be added and the only ones that the system would allow to add are IMEI's that were sold as unlocked or Sprint branded. If the IMEI can be white listed, then I am certain it would work.

I had a similar experience with an Unlocked Galaxy S7 and Sprint. I actually had to get Samsung Tech support on a conference call with a Sprint Manager, because Sprint told my customer the the phone is incompatible with the Sprint network. After embarrassing the Sprint rep, he white listed the IMEI number on Sprint's network and the phone worked.
Also, MetroPCS has the same policy. You cannot just pop in a Metro Sim card. You have to call them and register the IMEI number. After about an hour tops, the phone will complete provisioning and be able to work on Metro's T-Mobile network.
T-Mobile is instant. You cab pop a T-Mobile Sim card into any sim unlocked variant and it will work. However you will need to go into settings and follow the T-Mobile instructions on how to set up the radio frequencies. The better way is to just flash the carrier's ROM version onto the phone. This way you will get the features and updates from the carrier. Carriers seem to get the Android updates faster than Samsung. A trade off for bloatware.

You may have been referring to me regarding the unlocked Galaxy S7 & Sprint. Many thanks for that one. I'm going through the same crap now with Universal unlocked IPhone 7. Sprint is a PITA!
I can confirm the SM-G955U from AT&T does work. I confirmed this via Sprint site. Just Google Sprint byod eligibility and you'll find the link.
My biggest roadblock was AT&T had a network lock on my phone so the sim Sprint sent couldn't be used. I then used the services provided by gsmzambia to network unlock the device. It's currently working on Sprint network.

Are those places (sites) that you pay to unlock your phone legit? Is it possible to unlock the Verizon version of the G6 so I can use it on T-Mobile or does the Verizon G6 not have the proper bands support?

Verizon doesn't lock their LTE phones. You should be able to drop a SIM card in it and have it work.
I don't know about all the LTE bands though.
I'm on Verizon. Seems everyone I had would work on most carriers out of the box. I had S7 Edge (Verizon) worked on a few different prepaid Sims. I also added a new phone for me and put a dif sim in my old LG Stylus and sent to my son in Boise. And put old sim in my LG G6 and it worked (cause I needed old number in new phone and new SIM went in older phone.
Hopefully that made since haha.
Just remember that the phone/SIM must be in good standing or you will have problems sometimes when activating on major companies. Unless its prepaid SIM you can pop a new one in that's already activated.

I'll have a chance to buy new Verizon LG G6 for cheap, but I'm on AT&T network. Just want to confirm before pull the trigger, do I need a Verizon SIM to activate the phone first then swap with AT&T SIM, or just put in the AT&T SIM would be fine? Thanks in advance!
Put the att sim in, during setup connect to WiFi. After setup input apn settings. Restart the phone. The phone may occasionally inform you that the inserted sim is not a VZW sim. I think that will go away after you disable all the VZW apps.
I have tried different sims but does not recognize the sim. Only recognizes verizon sim. I'm not a verizon customer and where I am at we don't have verzion.
any suggestions will be greatly appreciated.
Update: Working now. Sim card readers were bent.

I'm sorry but where I live don't have Tmobile or Atnt. I was getting 4g LTE with my carrier.
Was having an issue with the phone losing signal when in poor reception area. Do I need ATT to activate phone with imei of xz1 or in order to get LTE do I need to have a previous att branded phones imei on the sim card? Is there any ATT bands this phone doesn't support? Just don't know why phone says no service when it is in a bad reception area. My iPhone 8 works perfect in the same areas.
Use an IMEI of a LTE AT&T phone if possible. If you give AT&T the IMEI of this phone it won't be in their database and it will be provisioned as a 3G device at best.
Do you have any issues with it losing a connection when there is poor cell phone reception?
****, this phone isn't functioning with AT&T LTE? That's a problem... Can anyone else confirm?
I have AT&T. When I got the phone I called them, gave them the IMEI and they did whatever they need to do and my phone works with LTE.
I had previously contacted their technical support before getting this phone to verify that band 12 would work as well.

Log into your AT&T account online and see what they have for a device for your number. It works fine on AT&T LTE but I have had issues for years when giving them the IMEI of my Sony phones. Maybe they have joined us in the 21st century.
So, from what I have been reading online and asking my IRL friends, it seems like AT&T doesn't exactly let devices that aren't sold by the carrier automatically have provisioning for LTE and LTE+. You have to call them.
Only negative in general is that VoLTE and Wi-Fi Calling cannot be enabled as a company policy at this time on phones not directly sold by the carrier. Even the Google Pixel 2 can't get VoLTE on AT&T.
...Anyway, solution so far is to call AT&T via 611 or from another line at (800) 331-0500 and ask to "Activate my SIM"... And then ask for an agent. You'll need to give them the IMEI of your phone.
Only then, after you reboot your device, will your phone be provisioned for LTE.
Is this all correct??
I haven't had success giving them my Sony IMEI. I have a carrier version LG V30 and when I bought it, AT&T gave me a new sim. I pulled it and put it in my XZ1 and I have LTE.
As augie7107 mentioned, the trick seems to be getting an IMEI of an AT&T phone attached to your account and sim and you can get LTE on other non-branded phones. The sim I've been using has been the same one I've had since a launch day AT&T iPhone 6. I've used the sim in a number of unlocked Android and Windows phones without major issues: Nokia 925, Moto X Pure, Amazon Fire phone, Nokia 930 (no LTE), Nexus 6p, Axon 7, Xperia XZ, XZs, XZ1, and now an Essential PH-1.

What did the AT&T agents say when they wouldn't activate LTE?
When I received my XZ1c last week, data would not work at all - LTE or 3G.
After playing around with settings for an evening, I chatted with the AT&T service rep first thing the next day and he was happy to enable LTE using the Sony IMEI. I don't know if it depends on customer service agent, or if there is a policy difference, or what.
I have been reading a lot of different things about doing this with no definitive answer. It looks like, as of recently, it should be as simple as popping in the sprint Sim card and it should work but I want to be sure before hand. Are there any downsides at all about using tmobile Note 8 on Sprint?
Hi there, I'm not sure but Sprint SIM cards are lock. You can try and see, I had Sprint before and try using there SIM card in my unlock tmobile Galaxy S7 Edge running the unlock S7 Edge firmware, it keep reconfiguring over and over. Maybe you might get better than me.

Sprint doesn't allow other carriers phones on their network. Unlocked or not. T-Mobile does though...
https://forum.xda-developers.com/galaxy-note-8/help/cdma-unlock-verizon-note-8-sprint-t3732364
First question would be: Does Sprint allow to use their SIM cards within non-Sprint devices? That I can't answer. Because I never used Sprint services.
The second question is: Would the T-Mobile radios work with Sprint? LTE radios would most likely work if Sprint allows you to use their SIM card with that device. When LTE is weak or not available the answer is: No. The active radios within T-Mobile and even AT&T Samsung Galaxy Note 8 are both LTE and GSM (Both 3G and 4G). Both Sprint and Verizon uses LTE and CDMA (each has their own CDMA) radios. You can't use GSM radios with Sprint and Verizon right now. Though that will end up changing as CDMA gets phased out.
To top things off each GSM carrier maybe using different frequencies with some (but not all) of their GSM radios. So changing a cellular device from a GSM carrier to another GSM carrier may have limits with GSM services.
Sprint and Verizon services have problems with international areas (outside of the USA) where LTE is weak or no LTE. The reason is that CDMA is very limit or doesn't exist in most international areas (outside of the USA). The areas that CDMA still works internationally (outside of the USA) will be phased out (mostly in the near future). Only a few places outside of the USA, like China, would CDMA not be phased out so quickly. But CDMA will end up completing phased out all together sometime in future (including in the US).
If you want to be truly Global then go for carriers that have both GSM and LTE, like T-Mobile, AT&T, etc. Then once you unlock the SIM then you can use your carrier's roaming (which don't need SIM unlock) or switch the SIM card with a carrier in that country to get service internationally. Just a side note: T-Mobile does have Unlimited 3G international roaming without any extra cost (this is subject to the type of plan you have with T-Mobile).
The only way this would work for you is if the CDMA radio is built into all Note 8 devices. If so then you just need to flash the correct radio firmware to active the correct carrier radios. But I don't believe this is the case. And this wouldn't solve the Sprint SIM lock issue.
The short answer is no. Read this thread. I thought you could just pop in an activated SIM, but it's not that simple.

ALL US Note 8s (N950U and N950U1) are identical. Same radios. Same hardware. Same everything. Only difference is the preloaded firmware. I actually think the Canadian Note 8s (N950W are the same, too, sonce they can run the N950U firmware).
So it's not an issue of missing a CDMA radio. It's an issue that Sprint will not accept the IMEI for another carrier branded Note 8 (or S8/+). You can only activate Sprint or Factory Unlocked devices on Sprint.
As Note 8 has both GSM and CDMA capabilities, why shouldn't an unlock T-Mobile work with Sprint?

On Sprints website it still does not list the tmo note 8 as compatible for BYOD. It says only the note 8 special edition is. However it is not unlikely they stopped blocking the other U.S. carrier versions. People have gotten devices to activate in the past, but with minimal network functionality. Is your Note 8 fully utilizing the LTE network?
Either way this thread brings trouble so its now closed
Sprint allows sprint capable devices such as clean sprint,Boost and such and subsidiaries that run on sprint only.
@cp1024 @Gizmoe
The Special Edition devices are the ones sold directly by Samsung as factory-unlocked models. Samsung over the years has used the term inconsistently across their site and marketing materials.
Only Sprint calls them "Special Edition", otherwise they are the U1 models, vs U for carrier branded.
Which means they as of the time this was printed will only accept this model
Maybe some others have managed to pull something off but this is official answer
my post above is how it has always been in the past
And it ends here
Pros/Cons?
Pro: No AT&T preinstalled bloat
I'm using an Essential PH-1 unlocked with AT&T. No problems.
Used a Mate 9 unlocked on ATT with no problem. Most US unlocked phones should work without any problems on ATT
VoLTE or HD calling as AT&T calls it might work on an unlocked phone if they will provision your line for the service. They did it for my Pixel 2 and it worked after I got a new sim. I don't think wifi calling will work on any phone except an AT&T device. I would make good use of this service so I'm opting for the AT&T version. If I find wifi calling works on an unlocked model I may switch but I don't think it will. We do some vacationing at a place with wifi but no cell service. My wife's AT&T iphone has it and it's pretty cool.
If the unlocked version is snapdragon then it will work just fine and lock to USA AT&T. With the S8 phones they were unlocked until you put a SIM in it and then it locks to that carrier. I'm curious is the unlocked version the exynos or the Snapdragon?

Having issues with SM-G965F on AT&T LTE
I just activated my SM-G965F and I'm only getting 3G and 3.5G (H+). No LTE. If I change the mobile networks settings to nxtgenphone, it connects to LTE, then drops and I get no data. I can only use the 'phone' version. My AT&T account has a grayed out device for my account. Checking compatibility with the IMEI checker for AT&T says it cannot determine if it is compatible. the 2nd SIM slot IMEI number is considered invalid!
Heading to the AT&T store at the mall later... not expecting much help.
I have the Note 8 and it was a PITA to get it full working on AT&T. Only thing that interest me was the Volte for talking on the phone and data at the same time, never got it working 100%. Had AT&T provision with new chip still not working good, so I sold the unlocked and got an AT&T model and had it unlocked and all is working well.

It was not the APN settings, entirely. It was that myAT&T would not recognize my IMEI number as a 9+. So, working with a store clerk at the local mall, she suggested to punch in a fake(last number altered) IMEI number using the in-store SM-G965U models. Since this has nothing to do with actually logging in or SIM verification, it worked. The SIM does its job and my account has an S9 (not a plus) on it, so when I changed to the 'nxtgenphone' APN settings, it is 'allowed' to log in (that's my best guess, anyway).
There is no other reason why the SM-G965F would NOT work on AT&T LTE since it has 3 of the 4 LTE bands (band30 is not included, but is only used in new, dense environments to alleviate network congestion -- my understanding).

So if I buy and ship an unlocked Galaxy S9 from Samsung website, it will have Snapdragon and not Exynos? I'm in a US territory.
I'm getting a good deal off their website with accessories and whatnot buying unlocked but I prefer Exynos
I'd rather not post and make a new thread. If someone else can confirm, I'd be much obliged
Yep it does. Just make sure it's on Snapdragon.
Hello,
My wife's Galaxy Note 8 somehow boots to different firmware based on SIM card inserted into it which surprised me since I thought that phones are usually coming with single firmware for either provider. I'm considering switching to T-Mobile from ATT and I have ATT branded Galaxy S9+ unlocked. My question will it have the same experience I noticed on my wife's phone or I have to deal with flashing firmware etc to make it work properly with WiFI calling etc features of native T-Mobile ROM?
Below message I received from Ebay seller which sold Galaxy Note 8. Is it true?
Thanks for contacting us. Samsung integrated new firmwares on S8 and newer model phones. Means whatever sim card you insert, it will program according to it. If you insert T-Mobile sim card, phone will restart and will show T-Mobile logo and apps. Same for AT&T and other GSM carriers. If you are AT&T user. Please insert the AT&T sim card and phone will ask you to restart the device with AT&T logo and apps. Tap yes.

Hello,
My wife's Galaxy Note 8 somehow boots to different firmware based on SIM card inserted into it which surprised me since I thought that phones are usually coming with single firmware for either provider. I'm considering switching to T-Mobile from ATT and I have ATT branded Galaxy S9+ unlocked. My question will it have the same experience I noticed on my wife's phone or I have to deal with flashing firmware etc to make it work properly with WiFI calling etc features of native T-Mobile ROM?
Below message I received from Ebay seller which sold Galaxy Note 8. Is it true?

If unlocked ATT branded GS9+ phone will work on any other carrier, what is the point of the threads below about flashing T-Mobile CSC (or whatever it's called) to ATT phone and vice a versa, etc if phone already supports switching between carriers on it's own?
