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.

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?

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.

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.  

Good to know, Is your battery not draining fast after this configuration change?  I did select the AP option before but the battery was draining fast and my phone started to heat up while charging (this wasn't the case before this configuration), I believe this is due to the phone keeps searching for the same network in these bands or something like that.

This definitely worked for me and the phone data is working better than before i must say:

 

Go to the phone dialer and dial *#2263# then Pick the SIM first selection. Then select clear all 
bands. Then select LTE bands, pick band 71, then select go to main. Pick 5G band, select NR band 41 sub 6 and SA and NSA, then select
NR band 71 sub 6 SA and NSA. Then select block set by AP option, then Go select go to main and then Apply band configurations.

Should be fixed after that.

I did this on my phone, after that definitely I have a better signal. (Before performing this configuration my mobile was had E, H+, 3G or 2G speed, after the configuration its showing 5G, LTE, LTE+, 3G) But still it doesn't hold that well, even though it says 5G when you try to browse something it will take forever to load and also while in a phone call I still gets chopped off during the call, my callers say I'm breaking up or they didn't hear me for a few seconds, so I have to keep repeating them again.

Are you using T-Mobile variant of Z fold 3 or Samsung Direct unlocked version of Z fold 3?
