Cannot Make or receive calls on non AT&T 4G phone. 3G sunset is to blame.

Re-posting this since the other threads all have "Accepted solutions". In my opinion "buy a new phone" is not an acceptable solution, and I will not be marking it as such. AT&T need to fix this issue.

About 2 days ago, my phone stopped working for any voice calls. I have a Galaxy S10+ and I just upgraded to One UI 4.1, and I think this may have been the start of the issue. If you have a non-AT&T Galaxy, don't take the upgrade, it will kill your ability to make phone calls.

To help others out, so far, I have tried the following and it *DOES NOT* fix the issue:

  • Restart the phone (several time). Of course this was never going to fix it
  • Call AT&T support and ask them to reset my wireless service, no help
  • Went in to the AT&T store and asked them to replace my SIM with a new one. Makes no difference at all
  • Did a factory reset on my phone. Doesn't help
  • Manually set the wireless settings according the the AT&T table in "Access point names" settings. Makes no difference

Just to be sure, I placed my SIM in my wife's phone (identical phone but she has not taken the One UI 4.1 upgrade), and her SIM in mine. My SIM works fine with my number in her phone. Her SIM fails with her number in my phone.

Conclusion: It's the phone, not the SIM, and even a factory reset won't help.

I think I know what is causing the problem; maybe one of the AT&T techs on this forum can confirm. AT&T have stated elsewhere that after the 3G sunset, having HD voice is a requirement to make calls, so there appear to be 2 requirements of phones:

  1. Phone must be capable of 4G; this gets you service so you can use 4G data and send/receive text message via SMS
  2. Phone must be capable of HD Voice; this allows you to make and receive phone calls

If you have 1. but not 2. you can't use your phone to make calls, but everything else would appear to work fine.

The thing is, a Galaxy S10+ should be capable of HD Voice calling, but I think my upgrade to One UI 4.1 may have broken it. In addition, I have a foreign S10+ with the Samsung branded processors on-board (different to the U.S. models). 

Any of the AT&T techs care to comment?

BTW: "Buy a new phone" is *NOT* an acceptable solution, please fix it.

Just noticed a difference with my wife's phone settings (an G975F/DS with UI 4.0).  Under About Phone/Status/Sim card Status Mobile Voice Nework Type and Data Type both read correctly as LTE - whereas on my UI 4.1 updated G975F  it reads as 4G.  So that is probably the bug.  Both phones are set to use VoLTE on each SIM (mine is not a DS). So the bug presumably has to do with the interface to VoLTE.

I can confirm exactly the same thing. Mine reads 4G, whereas my wife's reads LTE. I think you have nailed it.

I'm glad you got someone useful at AT&T, my last call got nowhere again, just another know-nothing (I did use another British term previously, but my post was deleted, and I thought they wouldn't get it ). 

So I guess we eagerly wait to see if AT&T will actually deliver on their promise and patch the phones within 48 hours. I'm glad you posted this; I was very close to using Odin to flash my phone back to One UI 4.0, something which I want to avoid if possible because of the risk involved.

Thanks - interesting app.  Gives the Network type as LTE etc

@balst01  Flashing the phone might be more extreme than buying an S22.  As for using British expressions etc - there are  many odd coincidences in this forum ;).

>I'm just not comfortable being bullied into buying a new phone, I like my S10+.

The S22 series also does not allow for an SD card or physical dual SIM.  So you would not be able to use your 512GB SD except with a USB attachment.  Although the S22 series is dual SIM capable - it only has one physical SIM slot and the other is eSIM - so you have to get the code from your provider for that.  I think the rationale for doing away with the SD slot is threefold: 1. They want you to spend more for more; 2. The access for internal memory is much faster than an SD; 3. Saving space within the device for other components.

Samsung during the launch gave folks the 512gb model for the price of a 256gb model.

Right. When I said I had the 512Gig S10+, what I meant was I bought the one that had 512Gig onboard (and also came with 8 Gig of memory). It does have an SD card slot, but I have never used it, mostly because I have noticed with the faster processors of recent phones, there really is a noticeable slowdown in access time (and app speed) when you use SD instead of onboard. I would figure with the S22, which has a much faster processor again, just having SD memory would slow it down, and give the customer a bad impression of the phone speed, which is likely also why they removed the option.

For my next phone, even if it has an SD slot, I probably wouldn't use it, although having 512 Gig is handy, so I would probably buy the larger memory size again (which restricts me to the Ultra on the current model)

I'm not an intensive phone user, and the S10+ is plenty fast enough, with enough storage and memory for my needs, which is why I'm loathe to upgrade, I just don't need more. Having a better camera and a bigger screen is kind-of cool, but not cool enough to spend $1,000. I was planning that my next upgrade will happen when they are no longer Upgrading the Android version on the S10+ (most likely when Android 13 is released next year)

Next year for Android 13?  I have it on pixel right now.  It will be out by fall.  The 10 series may not see it.

On pixel in Beta right now, out by Fall on Google platforms, and ported to Samsung by February next year, as per the usual Samsung porting cycle. And, right, the 10 series probably won't see this upgrade, and more importantly, Samsung will stop security updates for the S10 around that time, and release the S23 about the same time. So at that point,  it's time to upgrade the phone...that's my logic anyway.

I too have an unlocked S10+ SM-G975F. On Friday April 8th I updated to One UI 4.1. I have not gotten or been able to make any calls since the update was completed. Unfortunately the issue won't be fixed until Samsung and/or ATT acknowledges the issue and finds a fix. I'm so sick of reading "Purchase a new compatible device"

The problem is the update samsung pushed out removed the proper CSC file that was making it work before the current update..

To all those saying ATT needs to push a update to a F series phone.  THAT IS NOT POSSIBLE PERIOD.  ATT only has updates for the phones they sell.

Samsung directly updates its phones overseas.  The USA is the only place the carriers even provide updates on their own servers.
