Samsung Galaxy S10 Wifi-Calling not Working on AT&T - Samsung Galaxy S10 Questions & Answers

I have unlocked Samsung galaxy S10 SM-G973U1 (although on the box it said G973U)
So my question is how to change it to SM-G973U for wifi-calling to work on AT&T? and if I change it to the required version, is there a guarantee that wifi calling will work?

I believe you have to change the firmware so the system thinks it is an AT&T branded unit? My unlocked GS10 has wifi calling when i use it on T-Mobile or Verizon but has never worked on AT&T ..I hope someone can help you with the proper steps to change as i am not sure

AT&T disallows Wi-Fi calling on the factory unlocked S10. The IMEI of those units will never be provisioned since they are barred from AT&T exclusive features.
My advice is to ditch AT&T.

Agree with monkeydroid as I just ported my service over to Verizon and now I have WiFi calling and VoLTE AND much better call clarity and coverage, use same unlocked GS10

I have a galaxy s10 unlocked U1 though and not just the U. I'm reading that it can be flashed by someone on here and I can. Get it working again, I'm willing to pay for so help. It would be greatly appreciated

Better yet, use an MVNO instead and save money. I was on VZ before, but switched to Total Wireless and have been very happy. Same towers, half the price ($60 for 2 lines)...

2nd this very much. I use Mint Mobile (t-mo mvno), only pay 15 a month (4 gig data), have volte and vowifi, and it does carrier aggregation. Never had a phone that did that before... you get a little plus symbol next to the LTE symbol when it's doing that. The signal is almost always strong in the same spot where other devices almost always had weak signals.

[Q] Which Carrier Are You Going To Use?

As the title says ; ) Right now I'm on on a&t with a note 4 and plan on getting the N6 via play store then getting verzion for it, then I would eventually sell my note 4 but should I stick with AT&T for the N6 or go verzion. Had no problems with service but I think I can do better

AT&T. I'll never go to a CDMA carrier mainly because I change phones daily and it doesn't get any easier than swapping sim cards. I also absolutely LOVE their Next plan. Been with them for about 3 years now and have never had any coverage issues and I usually get about 30Mbps on LTE which is just wonderful.
AT&T.
Verizon since every other carrier is pretty much garbage where I'm at

Is it the same exact service as T-mobile prepaid?
Also does it support T-mobile's wifi calling?

Cricket (att mvno). I'll try tmobile again if the 700mhz comes here some day. I issued tmobile for years, but just sucks out of town or in buildings.
Verizon. Unlimited data!
Verizon....company pays for it...can't beat that...
Uscellular. Only carrier that gets decent reception where I live. Pretty excited they are finally getting some good phones.
T-Mobile.
Cheapest and best customer service.
Sprint. No problems with service around my area. Full bar LTE w/unlimited data.
Though I may switch to T-Mobile once they get better coverage.

Am I missing something? Ever since Verizon got 4G with a Sim card, I am able to just switch phones by switching out sim cards.... or so I thought

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.

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.

unlocked on Verizon

I'm not really new to this. I would always buy the phones, then root them when root was available. My question is if I buy the unlocked version and have it on Verizon, does anyone know what features won't work? Like I believe wifi calling on tmobile won't. But what about Verizon?
I THINK similarly, HD calling and Wifi calling won't work. I remember this from other discussions of unlocked Galaxy devices on Verizon.

Ok, thanks.... That is the problem I'm having cause I don't know about that part. Like I said, I normally just buy the phones then root them when root is available, but the s8 never got it or it took so long I didn't worry about it anymore. But I'm going overseas soon and would like to just swap sims and not worry about international charges
HD calling and volte should work. wifi calling a visual voicemail won't. check Samsungs page for compatibility.

My unlocked note 9 on Verizon didn't have any features except HD calling and VoLTE. I worked with Verizon tech support forever, they couldn't figure it out. They indicated it was a Samsung issue. Samsung said it was a Verizon issue. I sold it on swappa then got a Verizon branded one because I need WiFi calling and texting.
I really hope my unlocked S10 plus isn't the same.

I think Video Calling and Visual Voice Mail are for Post-Paid accounts only. I'm on Pre-Paid.
Plus I can use one of several other apps to video call, so I don't miss it. VoLTE and WiFi calling work great.
I can confirm that Wi-Fi calling IS indeed working on my unlocked S10+ on Verizon. Imagine that! The only thing I'm missing is Verizon's native video calling but that feature is so useless that it's not even worth mentioning.
Also, this thread is helpful describing all the features that work on Verizon:

Wifi calling and voLTE on Att only

Wanted to ask if anyone with a USA model rog 2 tried att Sim card and did it work with att? We already know t-mobile doesn't list those options. This way we can all go search for phones that will suit our needs.
My US model will be delivered either Saturday or Monday and I use AT&T. Will post my results then.
I just talked to support again, and they said no VoLTE or VoWifi on Tmobile, Verizon, or AT&T, or any American carrier. They have no plans to enable it. The suggestion was that I leave them a complaint, so I did so via their form on Asus.com as well as Facebook.
The problem is AT&T is shutting down their 3G service this year so if VoLTE isn't enabled we can't make voice calls.

As is TMobile, from what I understand. You should be able to make calls, but it will default to EDGE, IIRC.

Ok I just tried to confirm and got info they're not shutting down 3G just yet. We still have a few more years.
I guess that's good we'll still have calls but isn't good because there's no reason for VoLTE.
Thanks to ryououki for the offer, we will await your testing and we will be here if u need any help
I seriously don't understand a U.S model, yet no volte? That's just dumb. Wtf?
I can tell you right now it wont work, Its a sick phone but I'm sending it back because of this. Asus screwed up with no VoLTE, no VoWiFi, and only a 1080p screen IMO. Maybe next time they will get it right. I hope the OnePlus 7T and the 7T Pro has it... Crazy!
Just read this for T-Mobile:
Due to lack of VoLTE support you won't be able to place and receive calls including 911 calls in some buildings and some outdoor areas where 2G GSM and 3G HSPA+ signal (marketed by T-Mobile as "4G") is too weak or non-existent while LTE band 12 is available
Great info so far , just need someone to try it with att sim for confirmation.
So far we know,
Tmobile no go on volte or wifi call
Verizon works on data only no calls or txt just like rog one. Cdmaless option unclear at this moment .
Att no test yet
I have a US model on AT&T and can't get VoLTE yet.
I talked to AT&T support and they said there's no compatibility yet.
The IMEI doesn't come up in their system as a known device.
I have at&t and a USA version of the phone, I can confirm as well that the phone drops to 3g when making voice calls.
This is really really bad because at&t plans to shut down their 3g in 2021, that means no voice calls after that. Asus USA knowingly selling a $900 phone that cant make a call in 2 years is borderline fraudulent.

There has to be options somewhere we can atleast get VOLTE working. Yes root will be mandatory, but i am ok with that. I might order one from amazon. Whats the return policy for phones on amazon? Anyone know?
I believe there were reports that VoLTE was working on Tencent models?
We really need to look into making a custom rom for our phones for the US carriers.
Did you try dialer codes *#*#VOWIFI#*#* and *#*#VOLTE#*#*
How ridiculous. This is how you ruin a near perfect phone.

I did more research, it seems to be more on the AT&T side than on the Asus side of things. Barring a few well-know phones like the Pixel 3, most BYOD Android devices on AT&T in general don't get VoLTE, including unlocked versions of Samsung Galaxy devices that are not purchased through AT&T. It looks like AT&T does not enable VoLTE for device models with IMEIs that it does not recognize (i.e. doesn't have AT&T certified ROMs), because they are afraid of getting fined by FCC for non-E911 compliance which requires the carrier to certify E911 support on all handset/firmware when on VoLTE. My guess the Tencent models with VoLTE working are somehow whitelisted by AT&T ad-hoc or they are working on Non-U.S. carriers. So it is more of an AT&T problem than an Asus/ROM issue. (though there may be ROM hacks to ask the handset to force VoLTE even if AT&T doesn't advertise the capability during protocol handshake).
Since this is a much bigger issue than just the ROG II phone, hopefully they have a plan to white list all BYOD Android devices for VoLTE when they sunset 3G. Otherwise AT&T would stand to lose a good chunk of revenue from those who migrate over from other carriers with BYOD phones, say a Galaxy phone with a T-Mobile ROM. You simply can't even offer a BYOD plan if you don't have voice call working for most of the BYOD Android devices.

I'm pretty sure their return policy for phones is the same as all other goods. I bought and returned the original ROG phone last year through Amazon, considering doing the same with ROG II unless there's a breakthrough on providers and features with custom ROMS/etc.
Yea that's pretty dirty to whitelist the Tencent version but not the US model.

Bought T-Mobile Pixel 4 XL. If I get Verizon will Wi-Fi calling work?

Pretty much like the title states.
I have a T-Mobile Pixel 4 XL that currently has both AT&T and T-Mobile service on it. Rather than paying for two carriers, I'd like to just get Verizon as it seems to work everywhere here. T-Mobile is spotty as hell but the data is WAY faster than my AT&T.
I tested a friends Verizon SIM and did some speed tests but I forgot to test Wi-Fi calling which I will need inside my work building. That works on T-Mobile just fine but I can't get it working on AT&T. I see you can bug AT&T but no since if I just go Verizon anyway.
Thanks!

The TMO pixel 4 runs the same firmware as an unlocked phone bought straight from Google. If Verizon offers wifi calling on their plans you should have no issues.

WELL you would think but have you seen the AT&T thread about Wi-Fi calling on the unlocked Pixel 4 XL? GOOD LORD!
SO it seems AT&T blocks Wi-Fi calling on devices not *sold* by them so people are spending hours on the phone arguing with them and spoofing IMEI's to get it working. Some people are getting it done, others are sitting a wall and AT&T won't help.
Just wondering if Verizon pulls the same crap.

Have never had an issue with WiFi calling on any of my pixels - OG bought from Google and my 4XL from Amazon both have wifi calling (on unlimited plan).

I have Pixel 4 XL on T-Mobile and wifi calling works just fine. Can't tell you the spped since I never treated that but I use it inside the hospital where I work at since my cellular signal isn't the strongest

As far as I know as long as your phone isn't owed money... Meaning your not doing payments and you own the phone outright than yes. There is a setting under developer options called OEM Unlocking to unlock the phone from T-Mobile. Once unlocked from T-Mobile it will always unlock the bootloader.
At least that is what I read. I'm not sure how to do any of that anyway with rooting and such. I'm still trying to figure out how to screen recording on this phone.
Curious... Did an unlocked t mobile pixel 4 XL end up working fine on verizon? Like regular calls and data?
