I got the s23 ultra about 3 months ago and had zero problems initially. After about a monthi noticed people were calling but nothing was coming thru on my end. The only reason I noticed I missed a call because the caller left me a VM. If started as sporadic and now is nearly all the time. However if I switch my network to 4g I have zero issues. This includes using wifi calling. If the 5g is enabled even on wifi calling the call won't come thru. I switch to 4g and everything is fine! I've called the carrier tmobile and they couldn't resolve this I also replaced my Sim card Saturday and it's doing the same thing again! I don't have any sort of call blocking on, the calls are from people I speak to daily. Does anybody know of a fix or has anybody else had this issue? This is driving me insane!

Just an update. I tried every conceivable "fix" I could find online and nothing improved. I also visited a tmobile store and replaced my Sim card, nothing helped. My last option was to do a factory reset and see if there was an app causing the issue by installing them one by one and seeing what happened. Before doing that I switched a week ago from Tmobile to AT&T and so far I've yet to miss a call! (Knock on wood) I'm thinking it was either a tmobile app or the network having some sort of issue with my device.

you get the phone from TMO or Samsung? (I missed in your post that you mentioned TMO...my bad)

My bride has a S23U from Samsung with a TMO sim. she hasn't had the problem you described. you already did what I would have suggested...get a new sim.

I got it from Best Buy, it's an unlocked phone.

The Mrs had a 5g phone and had zero issues. I just bought her the new flip 4 a week ago and no issues with that one either. Only seems to be my phone.

I've also had issues with calls going straight to VM but never thought of turning off 5G. I will try going with 4G and see if the issue persists.

That's what tmobile suggested and I've had zero problems with 5g off. The minute I turn it back on problems with calls start again immediately.
