Bought unlocked S21, can do everything but make calls - Samsung Galaxy S21 Questions

I recently bought a used and unlocked S21 and everything works except for making calls. I am able to send/receive texts, use data, etc but when I go to make a call it instantly ends. Incoming calls go straight to voice mail. I tried dropping in the sim for another S21 from a known working S21 phone and the same thing happened so this is probably a setting on the phone or something. Is there anything that I can/should do to fix this?

Ok well a software update seems to have fixed things.

I don't receive incoming calls!

So, with the stock root rom, with a few different roms, and even with different kernels and radios, I don't ever receive incoming calls (though if I make an outgoing phone call, it works just fine).
Anyone know if this is something I can fix? Or is it an issue on Verizon's side? They had to go through three 4G SIM cards before finding one that my phone could actually activate with, so I'm wondering if that's the problem.
Did you set up call forwarding? Try calling *73 as this disables all calls to be forwarded, and try again.
You know what? I think you might be right... before I got my Thunderbolt, I had an OG Droid set to forward calls to a different temporary number...
My phone is going through a restore right now, so the INSTANT it boots up, I'll be dialing *73.
EDIT
VICTORY! It must have kept the call forwarding on the line. Thank you SO MUCH.
you're welcome.

[Q] [help] Atrix not recieving incoming calls

Hey all,
I'm having this issue randomly ever since I took a trip to Chicago this past weekend. My Atrix (only rooted) stopped receiving incoming calls from certain numbers. I've tried with a friend's AT&T iPhone and it works fine. But from my Verizon work cell I cannot call my Atrix.
When an incoming call comes in, the phone rings for half a second and then goes back to my home screen. No missed call log or anything. Immediately when the call comes in the phone's signal drops out and a few seconds later reconnects.
Everything else works just fine, SMS and data still smooth.
Anyone else have this issue? It's strange and pretty annoying.
Upon further investigation I have found that I can make and receive calls to those Verizon numbers if they are deleted from my contacts!
So Verizon + Contact = FAIL

[Q] No incoming calls

I've had the Galaxy S2 for about 2 months now without any problems.
As of last Friday, I can't receive incoming calls. People who try to call me hear one beep and then they get my voicemail.
Outgoing calls work just fine, as does SMS (incoming and outgoing).
I've put my T-Mobile SIM in another phone and then it is able to receive a call. Another SIM in my phone -> same problem: no incoming calls.
So I figured it must be the phone.
Customer support has started an investigation but that can take up to 1 week, so I thought let's ask XDA.
Can it be a simple setting that I've accidentally changed? Pretty often when I take my phone from my pocket, the screen is unlocked so that could be a cause.
If anyone has a clue or an identical situation, please let me know.

Does your phone ring when a call comes in and also does it go straight through to your voicemail?

Straight to voicemail. But I've figured it out after 3 days
There's an option to automatically block all incoming calls in the settings. Must have accidentally been activated when the phone was in my pocket.

In my case, the phone does not ring when I get a call at all. I have searched hi and low and I cant find a solution. I have rebooted, i have reflashed, I have changed my ringtone and nothing seems to work, please help!!
Hello my girlfriends SGS 2 has almost the same problem it cannot receive calls sometimes even though she can call everyone. The problem seems to fix by itself sometimes and it appears random.
I read that there was a problem with the samsung galaxy s when using 2G/EDGE connection with data activated and the problem was that the user could not receive calls randomly.
Can you confirm that you are using 2G/EDGE connection and Data activated? I am also trying to find the cause of this problem...
Hope my research helps good luck and waiting for your reply. (http://www.samsunggalaxysforum.com/...eive-incoming-calls-and-sms-while-using-edge/)
Later EDIT ---
She also has a vodafone provider but i have the same provider and never had this issue. Also no call filtering is done.
Make sure Call Forwarding is Disabled under Settings- Call- Call forwarding. And also try to delete the Voicemail number if you had set any.
Regards.
it's nothing Call Forwarding is Disabled related it is because of EDGE connection you can't have a sync or internet connection and while "dialing" data receive calls if you want to call anyone the network prioritizes and let's you dial whoever you want but it is not the same thing for incoming calls
^ Went over my head !
had the same problem in a bad 3g/data coverage area. solution was simply to turn data off and the calls started to come through.
turned data back on and now working ok.

[Q] Can't make outgoing calls, call barring active but deactivated...

Hello there,
Thanks for taking a look! I'm on the Note 3 (SM-N9005).
At a certain point I couldn't make calls anymore also messaging seems not to be working
When I try to make a call it stops after 3 seconds and says call barring is active.
I've tried stock rom, reset + erase data. Clean cache. I've tried the MMI codes and through there it says it isn't activated?
Also tried setting my network too GSM only and rebooting.
Still nothing would work.
As a sidenote: incoming calls and messages are working. Also my 4g isn't deactivated so it would be weird if Vodafone would just barricade my outgoing calls right?
I'll call them tommorow to be sure though.
If anyone has any idea on how to get this fixed I would really appreciate your help!

Call forwarding on AT&T Not Working

My call forwarding on my AT&T Phone and AT&T Gear S won't connect. Anyone know of any threads or remedies?
Fixed My Own Problem
Ok I fixed my own problem and now it works better than before. I got on the chat with AT&T and they set up the call forwarding on their end. The Gear S still says there is no call forwarding connection though, so I disabled the option. Since it is enabled through AT&T, however, on a remote connection I can receive calls from both my phone number and my Gear S number. All the while call forwarding is disabled on the Gear S. I can receive texts through both numbers as well. The only downside is, to disable the call forwarding I would have to contact AT&T again. But I don't really know why I would ever want to disable that. I'm just going to leave my phone in a constant remote connection and get all the benefits of a regular bluetooth connection plus the ability to receive calls and texts on my Gear S number.
Customization
Ok wait. To customize my watch, such as adding new clocks and wallpapers, I would have to be on bluetooth. But that's no biggie i'll just reconnect.
Nevermind
This method does not work. Calls to my original number do not show up on my phone. Just my watch. I missed a call today because I had my watch turned off. Even though my phone was turned on, I didn't see the call. It went straight to my watch which wasn't on. AT&T said there is no way I could get the same call to appear on both my watch and my phone. So I'm still out of luck on getting the call forwarding option thru the Gear S working.
