To get the G920a or G920i? - AT&T Samsung Galaxy S6

If I get the G920a I would defiantly be wanting to Odin the cricket firmware or an international stock right away. (I can pick one up tomorrow) OR Is it just worth to get the international G920i? (which is actually cheaper) How well does the i version work on AT&T? I know it has all the correct bands but the last time I owned a non AT&T phone, First was a T-Mobile Note 3 which couldnt stream music correctly without data cutting in and out. And then my Xperia Z2 from Europe would randomly have no service until I rebooted it when leaving my house/Microcell coverage.
Thanks. I thought I'd never come back to samsung but the G4 I tested is lag city and I'm getting bored of my iPhone 6.

Bell Galaxy S Vibrant

I live in the USA, using AT&T, and is shopping around for Galaxy S phone. The Captivate is the obvious choice under the Galaxy S flag. I just noticed the Galaxy S Vibrant from Canada today and I am really interested in it, especially because of the front facing camera.
How would I go about purchasing it? How would I get it working under the AT&T carrier? How is Edge, 3G, and voice, etc? How would future rom updates be installed? What are the down sides to buying the Vibrant versus a local Captivate?
Thanks
I have a Bell GS and on Bell it works great. Though after a firmware upgrade yesterday is is acting a bit wonky, might have to do reset.
To use it on ATT in the US you would have to buy it outright from Bell or other brick and mortar store that carry Bell phones. ie. Best Buy/FutureShop.
There is an unlock app for GS's and supposedly works on the Bell I9000, haven't tried it myself, no need atm. This will allow you to use a ATT sim card in the phone.
To update, you can use Samsung kies, supposedly what they will be using to push updates to GS, you can get that from samsungs web site. From what I have found so far you need to be in the touch wiz launcher to use kies. only matters if you use 3rd party launchers.
Not sure how the FFC will work for you. That might be dependant on ATT?
Your best bet, if you decide to get one. ROOT and make it your *****!
It would be 100% compatible on AT&T's network. In fact, it's even more compatible because Bell doesn't have a 2G network you can switch to to save battery life.
ROM updates come officially through Kies like normal, although you should also be able to flash most international i9000 ROMs you see floating around here, just make sure before doing so. Flashing a Captivate ROM just because you're on AT&T is a surefire way to brick your phone.
To buy it you will likely need to use something like eBay because even if you purchase it outright almost every store won't let you leave unless you have existing service with Bell. You can unlock it for free though with the method that I am sure is detailed on the Android Development board somewhere.
The obvious downside to buying Bell's Galaxy S is it comes at full retail price (over $500 Canadian) and in all likelihood you're probably going to get a model with the three button download/recovery modes disabled, making flashing ROMs risky. Hold out until the end of this month to see if Samsung Canada announces more about their promised fix for this.
I am using one on AT&T as well and it works fine. Best part is that AT&T doesn't force you on their limited smartphone plans and you can put it on a cheaper unlimited plan.
I got mine in a trade for a BB Torch but you can find one on eBay or maybe talk to a Canadian member here to see about picking one up for you. I would suggest you have them check for the 3 button recovery to make sure it's working before they buy it though.
The downside is warranty issues if it breaks but as long as the 3 button recovery works you should be able to recover from a bad flash and the hardware seems pretty solid so far so no worries there.
Based on the responses, I am definitely going with the Bell/Canadian Vibrant. The only trouble I have now is just finding one to purchase.
How do I post my intentions here to let people that I want one? Who is a reliable dealer here?
Many Thanks

the bell ones got both 850 and 1900 bands?
Also does it have a bell logo on it or is it unbranded.
send me a PM if you want to buy a Bell SGS with 3 button working tested, and GPS tested before mailing it to your address of choice.

Epic 4G (used as 3G on Bell / Rogers)
Hello,
I am interested exactly the opposite: I want to buy an Epic from Sprint (with no contract) and to use it in Canada (on Bell or Rogers) but only with a data plan, no voice (as I will use the SIP / VOIP). If Bell or Rogers offers only data plan, should this phone (Epic) works out of the box (or with the unlocking code) on the 3G network of Bell / Rogers, simply inserting their SIM card into the phone?

the sprint version is CDMA, chances are it's CDMA locked to sprint
CDMA unlocking is done on the server side, is not on the phone like GSM
you need to register your CDMA IMEI number to the say... Bell or Telus, if they see it on their server it's allowed they will let you in, if they see it listed as not allowed then they wont register the phone into their (Telus/Bell) CDMA network

Thanks for your answer.
I am not a tech, but the 4G/3G is also depending on CDMA? Or CDMA concerns only voice? Is it 4G/3G a standard (the same on Sprint and Bell and Rogers) that doesn't depend neither on CDMA or GSM?
we don't have 4G support yet in Canada
CDMA is for voice, but if you can not register the phone in the network for voice, you will also not get access to data
to have data you must have a voice connection
not a phone requirement but a phone network carrier requirement
Thanks.
Anyway, I checked right now with Bell and Rogers and no one offers only data plan... But what they will do with iPad and Galaxy Tab that doesn't support voice, but only data? If I will take the SIM out the gTab and put in a phone (Epic or Vibrant or Captivate), will the phone be able to work on 3G?

Yes, but if Bell already sells the dataonly plan for iPad, why they don't sell a dataonly plan also for a smartphone?
because they can claim a Tab is "not a phone" (whatever...)
and a Galaxy is a "phone"

I currently have a I9000 and am on ATT's network in southern california. I'm all but satisfied since my coverage is poor indoors and in some areas because of the lack of 850 band support.
I'm looking to move instead to the I9000M from Bell to get the added 850 3g coverage. Were you able to get a phone, root, unlock it and upgrade to froyo 2.2? Can you tell me about your experience so far including testing for 3-button boot into recovery? Where and how much you got the phone for out-the-door? Thanks.
Sorry mate, still waiting on mine, can't believe its been a month. An xda member here indicated that the stores in Canada are out of stock for awhile now.

[Q] Which Variant? N900T, A or N9005

Now on to the region lock madness, kind of. If a NegriElectronics T-Mobile variant is purchased it's supposed to be SIM unlocked already. Lets assume I or someone gets it and it is not. The easy fix for this is to use cellunlocker.net as others have to unlock the device. Does the N3 still have to use a North American SIM first before using another country's SIM? I ask because I've been contemplating on buying the device from Negri but I'm working in Afghanistan and using a local SIM for cellular and data services at my hip on my unlocked N2. When I'm home I stick my ATT SIM in with no problems but I only get HSPA + since I have the Exynos processor GT-N7100, which I have been more than satisfied with, only until I used my wife's S3 from ATT on LTE, then I was blown away. I've also contemplated getting the GT-N9005 International variant but then I would only get HSPA+ just as I do with my N2 now when I'm home. I don't like that US carriers change the interface which leans me towards the N9005 because it won't have any of the carrier bloat ware but the almost downside is that I would get only HSPA+ speeds, which aren't that bad compared to the connectivity I'm used to getting here Afghanistan on the local carrier known as AWCC which is getting EDGE.
Does the N3 still have to use a North American SIM first before using another country's SIM?
Is anyone using the GT-N9005 International on ATT? If so, how are your speeds, any issues?
-Typically it shouldn't be any issues as I've used my N2 with ATT for the last year from time to time by plugging in the APN correctly. Last time I was home I had to get a new SIM card and the APN settings were automatically set through the SIM card so even easier, just plug n play.
Thanks in advance for any assistance. I just want to make sure I get the right device. I'm so anxious to get my hands on this thing!!!!

[Q] HELP - Stay with AT&T or switch to T-Mobile

Hello Everyone,
Long time view, first time poster.
Let me start with, I'm so damn confused on what to do now...
I've recently (yesterday) upgraded (using AT&T Next) to get the Galaxy S5 (awesome phone, btw) and immediately starting looking into Rooting and Custom Recovery. Through all my searching, I find the same info, AT&T with it's locked BootLoader and no Root as of yet. I originally had the AT&T S4 that I rooted as soon as I got it, which had the unlocked BootLoader, so LOKI was awesome and I didn't get hit with the OTA upgrade to a locked BootLoader, so this is all new today. I know the SafeStrap stuff for the upgraded S4 but never had to experience that.
Now I have the S5. The dev's are awesome, so I'm sure there will be a way to root the S5 at some point, but it sucks looking on the forums every hour, hoping, but seeing the same CFAUTOROOT's for all the other versions, like T-Mobile, which brings me to my main question.
SHOULD I RETURN THE AT&T SAMSUNG GALAXY S5 AND GO WITH T-MOBILE???
Details:
I've already sold my awesome S4. I have 14 days to return the S5, but would have to link another phone to my account due to contact (till 10/2015), which is fine because I still have a Note and Iphone 3GS. I also see that T-Mobile will pay the cancellation fee for switching to them. The plan that I have with AT&T and the plan that T-Mobile is offering are roughly the same in specs and price, T-Mobile may even be *slightly* cheaper.
BUT...
Is it worth it to do this, just for the S5 with an unlocked BootLoader, that already has a Root method and Custom Recovery available, right now, as I type this...
I know, ultimately, I'm the only one that can answer this question; depends on how badly I want to root my phone.
I guess I'm just looking to see if other people are in the same boat as me and what their thoughts are on it, and what they are doing...
Any advise, comments, recommendations or in-sight is greatly appreciated.
THANKS!!!
If TMO has a good rep in your area then I would switch. Absolutely. Tbe S6 on ATT will even worse im sure.

That's a good point, and one I didn't even think about.
I have a prepaid $70 unlimited everything sim from T-Mobile. I find them to be good, not great. I live in Northwest, Indiana (suburb of Chicago). In my experience I find T-Mobile's LTE LTE signal to be pretty weak in general. Most likely due to the AWS frequency. The HSPA+ signal seems fine. I have also noticed that the LTE is not very fast (despite their claims). If you turn if off, the HSPA+ performs just as good, or if not better. I do not travel at all. But I like having a peace of mind with guaranteed HSPA+ coverage on AT&T. T-Mobile only gives me EDGE at home. It's 100% useless. I haven't tried out the wifi calling recently, but I wonder if you can send MMS over that.
I just returned my AT&T S5 for a defective headphone jack. I was going to exchange it, until it hit me that $700 is not worth it for a locked down device. I loved to flash custom roms and modify everything. AT&T has stopped that. Despite excellent coverage, I too am contemplating switching to TMO permanently. I like that they don't modify their devices. Maybe AT&T's system loosing my unlimited data plan today was the final straw.
Gonna look into options.

They had root for galaxy S4 from AT&T and bootloader is lock. Root is not proof.
If you check the tmobile forum you will see that they have rooted the S5, installed a custom recovery and some tmobile owners have even flashed and installed Indies rom from the International forum.

Ok some people need some education here, so here goes.
The ATT S4 Bootloader was technically LOCKED when it shipped. There was however a bootloader exploit that allowed custom roms and recoveries, this exploit was known as LOKI. Loki is not a true bootloader unlock, it is a bypass. It intercepts instructions during the boot process that allows unsigned code to be run. This exploit was patched in later updates by Samsung, and all current Samsung's are no longer vulnerable to the LOKI exploit.
The S5 on tmobile is BOOTLOADER UNLOCKED. This is confirmed. To those saying TMO is locked you are mistaken. I will enlighten you as to why. The root method used to obtain root on the TMO S5 requires an Unlocked BL to be successful. CF Auto Root by Chainfire works by modifying the stock recovery partition and then using ODIN to flash the TAR file. Odin flashes this modified stock recovery which then pushes SU binary which then flashes the Stock S5 firmware over. This only works if the BL is unlocked. 1 of 3 outcomes will happen if trying to flash on a locked BL. First if the BL is locked Odin will error out saying that the modified recovery image is not official/signed (end of story thats it), this is the most likely scenario. If somehow the modified image flashes onto a locked BL, the phone will not boot. Worst case scenario it flashes and you end up with a brick.
CF has already stated his root method won't work on the ATT S5 or VZW S5 because of the BL, worse is that modifying system to get root is not possible according to CF. This was used to root the S4 and Note 3 orginally. The only way the ATT or VZW S5 gets rooted is if a dev is able to find an exploit for Kit Kat.
In short TMO S5 has an unlocked BL and ATT is locked, stop being in denial. Class over.

This is an awesome explanation! Thanks! So technically, my S4 didn't have an Unlocked BootLoader, there was just an exploit Jellybean (LOKI) that was able to gain root (that I used) prior to Samsung patching. And that same patch (or "fix") is applied to the S5, right out the gate. :crying:
I'd, switch and all of us here that can't switch should let them know that because they locked their bootloaders. That we will all be switching carriers due to them locking the bootloader. If we can find the right place to tell them that they will be losing many customers then maybe they will change the way they do things or send us a unlocked update.
I had to call them yesterday with a problem with my sim. It was coming up not registered on a network. When talking with AT&T I told them when upgrade time comes I am switching to T-Mobile due to them locking the boot loader. That it should be my choice what I do with and to my phone that I paid for. Then today while doing a servay about the call. I told them again, at the end when they asked if there was anything else. After telling them again, the response was. Thanks again for your time and feedback. Your comments will help us continue to improve our service.
Now this is probably just a general response that's given at the end of the servay. But if we can find the right place in AT&T and threaten them with the loss of many consumers. Then maybe they will change some things. Just think T-Mobile in One year or Two seeing the trend of more and more At&t and Verizon consumers jumping ship to them. They will have no choice but to make T-Mobile better than the others, in all aspects.
Honestly, I am thinking of either going back to my Note 3 or doing the T-Mobile but I am not sure that the S5 offers enough new stuff to support the added expense over the Note 3.

Hi,
I'm also thinking about going to T Mobile especially because they
will pay your ETF for the switch. Just not sure about their coverage,
that's the only thing holding me back right now,
Ken
Or you could go with the HTC one m8 it's unlocked,rooted with a custom recovery and s-off.I had never owned an HTC device always had Samsung.but after handling the phone and how dev friendly HTC it's I'm glad I went with them still have my s4 anyway with Loki.
Second choice buy an s5 from t mobile unlock it and use it on AT&T , people have said that lte and reception is excellent on AT&T with the tmo s5.
I hate the fact that AT&T is going the Verizon rout but lays face tmo network is no where near AT&T .I've used both .hope this helps.

Thank you everyone for your responses!
I finally did it and made the move to T-Mobile.
LTE on T-Mobile is soooo much faster than AT&T. On LTE I went from between 10-20 MB/s to a minimum of 25 MB/s on TMO, and most of the time a solid 30 MB/s.
HOWEVER, I did notice that places where I would normally have LTE with AT&T, I only sometimes get LTE with TMO; otherwise it's just 4G, which knocks the speed down to between 8-18 MB/s from using speedtest, but still not a huge deal.
I do find myself 'waiting' for websites to load a little longer on TMO, probably slow DNS servers, so gotta look in to that to see if I can change the DNS servers used when using Cell DATA (not Wifi).
All in all, I couldn't be happier with the same exact phone, but that has an unlocked bootloader and already rooted and custom recovery. I was nervous about switching since AT&T did have GREAT service (and by service, I mean reception, lol) but glad I did.
So, if you have AT&T and the S5 and want/need root and are tired of looking for a Root and keep seeing the CF-Auto-Root available for TMO, take the plunge and switch... just check out service reviews in your area first.
Thanks again everyone!!

This is exactly what I will be doing when they get reception in my area. The people that voted stay with At&t either work for them or have high hopes. As there most likely will never be root for At&t's S5 unless they give it up and that most likely is not going to happen. So in all reality their votes don't count as there won't be root.
Thought I'd add my two cents here. I just recently tried out T-Mobile (again) and the more I used their service, the more I hated it. Of course this is subjective because not everyone lives in my area. After having AT&T LTE for years, you get use to it. When driving AT&T's LTE signal was stable. It would never drop to E or 4G. If your driving and streaming something with T-Mobile, FORGET IT. The LTE signal is EXTREMELY weak. In my area AT&T & TMO share towers. My AT&T LTE phone would show a -90dbm signal, while T-Mobile would show a -110 signal.
In my area they need low bandwidth spectrum to cover it. They will never get it here. I can't have my phone signal bouncing all over the place. Its annoying and drains the hell out of your battery.
I also found their LTE to be slow. Much slower than AT&T's (in my area). So anyone who switches to TMO and has great service, I envy you. For me, it wasn't what I thought it was, after a few days of use.

Worth buying N910T?

Hey T mobile users, I currently have a Sprint note4 unlocked on Cricket network. As you may know I only get hspa speeds this way, Not a super big deal to me. As I've had the phone this way for a year now. Only reason I even ended up this route is because i got the phone (at the time) real cheap from a relative.
But now that I've seen the prices drop quite a bit cause of its age, my question to you is first will the t mobile phone get lte speeds with Cricket(at&t)? It looks like to me it has them bands.
Second, Do you think it's worth the hassle? I figured I could comp the price by selling mine afterwards.
Your advice and opinion is appreciated. Thank you!
It WILL work, but it isn't worth the hassle. With T-Mobile you would only benefit from VoLTE and WiFi calling. You can root your existing phone and flash a ROM with the T-Mobile system files and keep your.
AT&T and T-Mobile note4 is the same hardware-wise except the bootloader, modem and corresponding kernel required to make WiFi calling work for the N910T. The N910A is punished with the locked bootloader, so I can see your concern.
If I understand you correctly: You wish to keep your current carrier, but to switch phones just to get LTE speeds?
I have a 910T running on Cricket's network. I think I paid $150 for it used which was a huge upgrade from the HTC Desire 510 I was using. It had a burnt in screen but I learned to deal with it for $150. Also has some other quirks that usually only show when a phone's been water damaged. I learned to deal and get around them though. Because of this, I don't recommend buying a phone used. And since you're content with your Sprint model, I might just stay with that.
The reason I went T-Mobile was because of the unlocked bootloader. And there's no doubt in my mind that I'll have this phone for another 2 years. It's a great phone and after Samsung took a bunch of features away with the Note 5 and then created an exploding Note 7, I'm quite happy with this device for a while to come. Now the rumor is that Samsung might be taking away the 3.5 headphone port. If that's true, **** them. I just used my headphones for over 6 hours on a Greyhound bus and Bluetooth requires charging which I don't wanna deal with.
I can't tell you what to do but if it were me, I'd stick with the Sprint model. But I do love custom ROMs so...
****If you buy a note 4****
Only buy a refurbished or recertified one with a full warranty...
There's reported issues with these phones real or imagined... don't take the risk!!!
Good Luck!

N950N Note 8 256GB working on at&t

SO I picked up a 256GB emperor edition from Korea. It is Confirmed to have every single LTE band that AT&T uses. I put my sim in and only get 3G not 4G. Called at&t and they said they need to re-appropriate the IMEI for the USA as it comes up as a 2g/3g phone because the SKoren SK telecom IMEI assigned to the phone is different in the USA. IS that True? Anyone know how and if I can get the Phone to work on 4G LTE on at&t or do I have to hope they get it right? I paid $1400 for this phone I don't want to use a 64GB version I have been waiting to have 500+ GB on a phone for so long.. Any TIps? Hints? Recommendations?
EDIT: for those reading this thread for the first time. As of 10/9/17 I was able to get good LTE speeds as well as WIFI calling and Video Calling on my N950N note 8 Korean Exynos model. In a nutshell here is what I did to make it work.
Flash nemesis n950F rom to my phone.
Flash AT&T CSC to the phone using the CSC tool and you do have to modify one line (user RED FLAME) has this in the CSC thread.
Call at&t and give them the IMEI of a VOLTE wifi calling/video calling capable cellphone (I used my wifes S8+ - and yes you can DOUBLE USE IMEI on the same account)
I also did one other thing - Check page 14 for that information.
I just wanted to give a synopsis of this thread so new N950N and at&t owners don't feel like they are wasting their time searching XDA and google. I only wish other people did this when their problem is solved so people can easily see they are not in the wrong place and don't have to read tons of pages of stuff.

SO I picked up a 256GB emperor edition from Korea. It is Confirmed to have every single LTE band that AT&T uses. I put my sim in and only get 3G not 4G. Called at&t and they said they need to re-appropriate the IMEI for the USA as it comes up as a 2g/3g phone because the SKoren SK telecom IMEI assigned to the phone is different in the USA.

Hi.
There is a thread somewhere here they were talking about similar problems.
What you where told is essentially correct. Though they also said that they needed a new sim card, too.
Hope this helps. Still waiting for my Note 8.
Too bad those devices do not have the CDMA bands...
I have the same model and same problem but with softbank, though softbank has been less helpful.. i read someone flashing a different csc (if its the right one) will "unblock" the phone? Would any exymos model csc work?
My roaming menu is also greyed out... not sure if that is related.
I think you just need to give them the IMEI and have them set it up for LTE in their system, since they don't by default allow LTE on bring your own devices.
Did you change the apn? I have the same phone on tmobile and i changed the apn to the tmobile apn and i have no problems with the phone.

Just a quick comment - I think you mis-spoke. ATT Does allow LTE on Bring your own devices. I have been using G955F variants for the last 4 years and never had to do anything other than put the SIM card in for it to work. HOwever, LTE Enhanced Services are not available on Bring your own Devices. This includes HD Calling, Wifi Calling and Video Calling. BUT, LTE will work.
I don't know anything about the Korean Model so I hope the OP is able to get things straightened out - but other variants have always worked on ATT - including TMOBILE PHONES and international variants as well.

That's probably what I meant. I haven't been an AT&T customer for many years, and have been with T-mobile for all my smart phone career, and they don't require any special setup on their end for VoLTE, Wi-Fi calling, etc as I can confirm with my Korean Note 8. After somewhat jankily switching CSCs with a modified script that was originally made for S8 and 8+ phones I definitely have VoLTE and probably have Wi-Fi calling working without any communication to T-mobile.
Waiting on at&t now.. to see what happens.. SPEC for SPEC this phone is exactly the same as an at&t phone. It has every single band, not missing a single one. If you put the specs side by side there is ZERO difference. I changed the APN - there are 3 at&t choices. One gives me 3G the other 2 do not work. SO waiting on at&t to re-appropriate the IMEI to register as a note 8 on their network. I had not idea it was going to be this much of a pain in the arse. I was told by a few sellers, pop in your sim and your good to go. I did need a new sim since my note 4 sim did not fit in the note 8, so They gave me a new sim. I put the sim (using an adapter) back into my Note 4 until they change over the IMEI and the new sim works just fine on the note 4 - all my video calling, wifi calling and tethering work fine. So hoping I do not need to return this phone and use a 64GB model. I wish samsung would just release the 256 here on at&t like apple is doing with the iphone X. I would pay $1200 for it no problem. (and since the iphone X is $1149 with 256gb - I am sure samsung would do $999 or $1099 to undercut apple. But Samsung is going to epic fail and never give the US customers what they want.
Hi there, I would also like to have the Emperor's edition, and use it in Canada (Bell) and USA (T-Mobile or AT&T). Is N950N the correct model number for this edition? Does it come with dual sim? Thanks! So far I found an Ebay seller from Hong Kong with F950FD which looks to be 256GB Duos - I'm wondering what the difference is with N950N and whether I will have an issue with region lock?
Thanks for any comments...
I have the unlocked version on at&t and this is my son, just in case...

Did you need a new sim card?

No, I was using it on a HTC10 and previously on a Note 4...
Totally DIsappointed... No way I am keeping this $1300 phone for how crappy it is on At&T.
They Finally Updated the IMEI so that is shows up as a next gen smartphone on at&t network and I get an LTE logo. I set my own ACCESS POINT as well as used all 3 that showed up automatically. ATT Phone, ATT NEXTGENPHONE and ATT UTDATA (Nextgen) + I did what was recommended on att.com for bringing over a phone that might not get the access point which was the same settings as ATT Phone - all of them gave me LTE on my bar and showed AT&T as the network. Every single LTE Band on this phone is the same as the official ATT note 8. Yet on my speed test I couldn't get better than 4MB/s down and 1.56MB/s up, my note 4 (pop the sim card back in there) even with 1 Bar on my phone I get 42MB/s download and like 10MB/s Upload.
IT is too late to call at&t tonight but I am extremely disappointed. I have wanted a phone with 256GB of memory for like 2 years now, and to have MicroSD expansion for just MUSIC (NOTHING ELSE).
If At&t can't get this note 8 to perform exactly like a at&t version would, then I either going back to my Note 4 or Perhaps the US Samsung unlocked version (which I already have but is not opened as I hoped to sell it and make a few hundred on it to make up for the $1300 I spent on this Emperor Edition.
Any advice?
Anyone want to buy it.. I paid $1299.99 Shipped from NK. Instead of returning it - if anyone wants to buy it, id do the same thing $1299.99 shipped anywhere in US or Canada. Perhaps it will work better on another network...

Does your unlocked version work as it should.. FAST LTE 4G LTE? Does your WIFI and Video Calling work?

Have you Odin the CSC and IMS? From what I have read that needs to be done?
Sent from my SM-N950U1 using XDA-Developers Legacy app
No, I haven't flashed the CSC profile, no wifi calling or VOLTE but internet speed is fast...

tl;dr - Under Settings->Connections->More Settings there's an option titled Reset Network Settings and, i had to use that on my Korean, Note Fan Edition to get LTE working.
more detail on how i got VoLTE and HD Voice working.... i grabbed an ATT (Snapdragon) S8+ CSC and manually applied to the FE. To get HDVoice and VoLTE working, i called ATT and told them i was going to use my (no-longer used/retired) ATT Samsung S7Active with my cell number. this step was a must to get VoLTE working. once they associated S7Active IMEI with my cell number, i rebooted the Note FE and VoLTE was active. i occasionally receive calls and the HD Voice icon appears on the dialer screen; i assume the other person is calling me via Wifi when i see the icon. Video calling and Wifi calling haven't worked for me on none of my international devices. once i got my UK note 8, i applied the same CSC content (after rooting my device), i inserted the same ATT sim used in the Note FE, reset network settings and VoLTE and HD Voice (when receiving calls) still works.
I don't know about the Korean model, but here is how you get Volte on ATT on the Note 8 F model. https://forum.xda-developers.com/showpost.php?p=73851525&postcount=308 After you slightly modify the zip and flash this, you must call ATT and give the friendly customer service person the IMEI of a phone purchased from ATT directly that is roughly equivalent and had Volte and wifi calling features. I used an old S7. ATT will NOT accept an IMEI of any phone not sold by ATT. Once they put it into their system, reboot your Note 8 and whala - wifi calling and Volte work perfectly.

Kind of a NOOB when it comes to all this. I haven't flashed or done any phone hacking in a few years (my s4 was the last phone I really played with).
SO I downloaded the CSC Selection V1.2.1 on Android Filehost
I honestly do not know what to do from here.
Thanks.

did you try resetting network settings to at least get LTE going? Under Settings->Connections->More Settings there's an option titled Reset Network Settings and, i had to use that on my Korean, Note Fan Edition to get LTE working. Or are you good to go on LTE?
