Hey guys... This issue happen to me as well. I bought my phone directly from Samsung ..after I did the update my phone went to crap I took it to 3 different TMobile stores and changed sim cards thinking that was the issue ..finally decided to ship it back to Samsung . 6 days after I sent it I received my phone back they told me the replaced the mother board on my phone and said it was fixed. When I opened my box from their shipment my phone was scratched. Btw I had the phone less than a month before this. I said w.e I just need/ want my phone back as I use it for work and personal use. Put my sim card and  NOTHING still the same problem immediately called them back. 2 hour wait time so I decided to have them called me back when it was my turn. 2 1/2 hours later they call back. I answered.. says I'm first in line and my call with be answered shortly 45 mins later nothing no one ever answered so I hung up. I called Monday and they said someone should be contacting me but the end of the week. Today Thursday I called they told me they were going to refund me my money because the phone couldn't be fixed. I turned in my note 10 which was flawless at the time and now I'm stuck with out a phone. Really annoyed and frustrated with the way Samsung has handled my situation !...looking into another Samsung device because I can't stand iphones 

Sorry to hear that you really had a bad experience with them.  I had so many Samsung phones in the past, but this is the first time ever I face this kind of issues and this is the most expensive phone I ever bought.  Plus their customer service is getting worse, up to a point we end up dealing the issues on our own.   I'll probably just wait until end of this month to see if they gonna roll out a security update with any fix for this.  For now, i'll have to rely on the WIFI for calls and internet connection.

When I attempt to call the *#2263# I get "USSD Code Running" and then I get an "Unable to process this request." I'm on a Fold Z3 purchased directly from Samsung. ¿Tienes alguna idea?

I have unlocked one. I did all the troubleshoot steps. But still can't connect to the network, even the work around, I can only connect for a while then I lost connection again. I brought my phone to drop off at UBreakIFix since they are partner of Samsung Care, and they found nothing. The next day, I called Samsung and told them all the troubleshoot step I did, included downgrade to Android 11 but still no connection, they transfer me to Care+ and right away they send me a new phone, which came in yesterday, with perfect connection on Android 11. I upgraded to Android 12 and it worked fine till now. Looks like the root cause is the cellular antenna itself. Some people on other forum sent their phone back to Samsung and got mainboard replaced which fixed the issue. 

That is a great news!  Did they give you hard time with Care+  Do you have to pay anything extra or it's just a quick easy mobile swap?  Also, did they give you a brand new phone as a replacement or it's a refurbished?  Any details will be really helpful.  As I'm also in the same boat, mine is an Unlocked device directly purchased from Samsung.

I have no hard time at all. the guys from customer services was awesome, he right away understand that I'm a power user, since I know what I have to do to troubleshoot. He right away transfer me to Care+, and they send me right away new replacement phone, no refurbished, it is brand new from a new sealed box. The Asurion may need your card information in case you won't send back the malfunction device, they will charge you. if you sent the malfunction device back, there is no charge at all since my phone is under warranty.

after i updated my phone to android 12 my service got so dam bad i wish i dint do it my z fold 3 is slow and the service is patchy and im tired of talking to a rep it seems all i get is a reset your phone and that could help this a 1800 phone i might get rid of it and get the galaxy S22 ultra if this phone does not get any better

Hola,

I also have a ZFold 3 with the same network issue after the update to Android version 12. However, only 1 of 2 of my phones have network issues. The one with the network issue with "BUILD NUMBER" "SP1A.210812.016.F926U1UES1BUL7” and the other one with “Build number” ended with xxxBULA without an issue.  Please share your "Build Number" if possible (Setting>About phone>Software information>Build number). ¡Gracias!

It looks like it doesn't matter what build you have. I manually install those builds, included android 11 but the connection acted the same. This could be related to the hardware issue. Since the ZFold kinda hot when using data and charging, especially when using android auto. That could be the reason for the antenna malfunction.

Mine ends with BULA, but I'm facing the issue. I think it's based on when & where the phone was manufactured.

Hello Bryan Vo,

If it's the antenna malfunction (hardware), how is changing the band configurations (software settings) got it working again? I'm puzzled by your comment...

I did not say the work around by configured the band work for me. And if that the software problem, especially from Android 12, why downgrade to android 11, the problem still exist? The phone came with Android 11 out of the box and no one had problem with Android 11. You can see the answer there.

I have switched my SIM card to my husband phone and I'm able to place calls, but when I place his SIM card on my phone it doesn't work. I made a couple of calls on his phone my SIM card, and mine phone his SIM card.

It's been 4 days, and no expert is able to help. Now my phone is constantly searching for a network as soon as I put the T-Mobile network Internet work operators. Not able to do phone calls not able to receive phone calls.

Apparently it's a z fold3 issue.

I placed a complaint on samsung members app.
