Keep in mind, if you restart your phone at anytime, the above fix will reset and so phone will go back to no service and you will need to do the fix again.. 

If you check the block set by AP option it should keep your band settings even after restart.

So far going in about a day after doing the work around I found and I have had no issues yet. 

Fix worked for me too.  Thank you for sharing!  

Im using a unlocked phone from Samsung. Did you make sure to the choose block set by AP option before applying?

everything you named was happening with mine as well before i did that and since then i havent had any issues accept for Tmobile had an outage in my area/ region and i was down for a bit on Tuesday.  

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 

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.

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!

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

did you notice i responded to someone else? its even included on my actual post as to whom i was talking to.

THIS IS WHAT I DID TO FIX IT: 

I had same issues. H+ service or no service at all. Tried all troubleshooting.  Reset networks clear cache. I called tmobile and samsung. Nothing worked. But I tested my unlocked zfold with a sim card from ATT and phone worked perfectly.  Then put the tmobile Sim back in and it fixed it. When you switch Sim it forces phone to reconfigure for the Sim inserted. So when I reinsert the tmobile Sim after having phone configured to att it had to reconfigure to tmobile Sim again. It seemed to fix issue. I can text call and use mobile data again 5g.

Nevermind.. It only worked for a few hours :( its back to being crappy service. I have to put on airplane mode and back to get spurts of service.. I just spoke to a tmobile tech and they told me that there will be a new update released next week...

correct..everyones phone didnt just up and blow up its antenna right after an update..the update itself messed up how the phone now reads and attempts to use the network..which is why for many changing around which bands the phone looks for has fixed it for the moment as pointed out above my post..

Samsung just needs to get their update figured out and then fire out another update to fix this one.
