[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!!!!

AT&T on T-mobile S5

Hi, I got a T-mobile S5, and unlocked it. My 3G works but LTE won't register, I am 100% sure that the APN is correct.
Any ideas what I am doing wrong?

-You need an att modem file flashed on your device, but im not 100% sure. Ihave my stock rom files from kies and amoung them is my csc file. Keep reading. Get to know your phone.-
Someone please confirm this is the right route and I will share my csc file with you
Start by rooting your phone and getting a custom recovery (Philz). Check the tmobil section of s5 ...

He does not need an AT&T modem flashed on his device. That would most likely result in a brick.
OP: Try dialing *#2263# and make sure automatic is selected. Also go into setting, mobile networks and set it to LTE/GSM/WCDMA

I tried to do LTE only and it has the right network code, but it won't activate. I checked my ATT online profile and it doesn't have a "LTE" data plan and I think that is the problem. I'll try again tomorrow once it takes effect and report back

Ok you need to give ATT the IMEI number from one of their LTE android devices. Just go to the store to get one from one of the demo devices. Then your account will be provisioned for LTE.

The guy above is correct, you need at&t to register your imei into their network to access their LTE.... They should do it for you no problem, just give them a call....however I wouldn't be surprised if they don't! Another way is to find someone with an extra LTE phone and just activate that imei and your LTE should pop up

If he registers his T-Mobile S5 on AT&T he will still have problems. AT&T won't recognize the T-Mobile IMEI number, and therefore it will list as a GSM device.
He needs to find an IMEI number of one of AT&T's LTE android devices. Once he has called AT&T CS and have had them provision his account for LTE, then he can just pop in his AT&T sim card to his T-Mobile S5. He'll get LTE then.

Just wondering where did you unlock the phone from and how long did it take to get the unlock code?

Thanks for everyone's help. I am good to go.
I took a SIM from another LTE device. I think it does need to be registered as a IMEI from an ATT device and that was the problem.

Now that you are getting AT&T LTE on the T-Mobile variant, can you please comment on LTE signal strength? This is a deal breaker for me. When I had the TMO Note 3 on AT&T, LTE reception sucked. If you can compare it with an AT&T branded phone, that would be great.

Another person using the G900T. Congrats
My experience is that coverage is just as good if not better. Same radio, same antenna, I wouldn't expect it to be any different?

The TMO GS5 has all the needed ATT LTE Bands no need for a radio flash, I'm using one on ATT now, have gotten LTE from day 1, as stated only requirement is the sim has to be originally activated on a LTE ATT device and that the APN is set properly.

What kind of speed is everyone getting with the tmo s5 on att network? I have an att s5 next to a tmo s5 and att s5 is getting 50mbps vs tmo at 20mbps. I am wondering if I needed to configure something on the tmo devices?

Check your APN setting. The T-Mobile S5 should have the same exact APN settings your S5 has. Can you also comment on LTE reception on the T-Mobile S5 using AT&t?

APN is exactly the same as AT&T one. Reception is also same as AT&T one but the speed is a show stopper if it's half the speed. Any one have any ideas?

I wouldn't sweat the speeds, unless you keep noticing it. Try again later. Perhaps the T-Mobile S5 needs a modem update? Keep us posted.

I would also like to do this, but I just want to clarify something. I just bought an AT&T S5. Brand new, unopened, still in the box. I want to swap it for a T-Mobile S5, as the bootloader is unlocked. If I keep the AT&T SIM card before I sell it, and put it into the new Tmo S5, will I have any foreseeable issues? Will it work just like that, or will I need to retrieve something from my S5 before I swap it?
Thanks.
EDIT: I should clarify that the device is unactivated, and when I do activate it, I will be porting my existing number from Verizon.

[Q] Note 4 and International Hotspot

So,
Here's my question I am hoping someone can answer for me. I have a TMobile branded Note 4 that I have unlocked. I am going out of town in the next month or so internationally and I have not had an opportunity to see if the hotspot works without issue with a local sim. I know this obviously depends on if the carrier allows it.
So, is there anything that would prevent me from using the hotspot internationally with a local sim on a carrier that allows it?
I ask because previously I had an ATT GS4 which I never got to work with an international sim with hotspot enabled. Any input would be appreciated.
TIA

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.

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...

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...

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.

How well does the Verizon S10-5G work on AT&T?

I've seen that people on here have been flashing the Verizon variant with the AT&T via odin. I was thinking of buying a Verizon Variant and flashing it with AT&Tas well. But I would like to get some opinions first and see if anyone has had any trouble.

I haven't flashed AT&T on it but using on AT&T and it works just fine....

I'm not using it on AT&T, but haven't had a single issue on my network.

From what I understand, you may be fine on LTE, but you will not be able to use the 5G from AT&T on the Verizon phone.

S10 5G from Verizon without flashing on AT&T?
How? I put in my ATT Sim card, get signal but when I open Google chrome it turns into no signal or as if I didn't have a Sim in it. Frustrating.
Did you had it activated to Verizon at the beginning? I heard for it to work elsewhere it'd need to be activated with Verizon for 60 days, then I can be used anywhere. Not entirely sure. Can you confirm?
