I have my bosses number stored in my phone in the contacts. But when he calls my phone it goes straight to voicemail my phone doesn't even ring when he calls. But all my other contacts get through with no issues.
Comment above me is correct. Your carrier can flash your sim remotely, after this power cycling the device should restore normal functionality. If it does not the diagnostics tool would be my next step before putting in a maintenence order with Samsung
Did you accidentally block his number? Blocked numbers don't ring, but still go to voicemail. This can also happen if he's calling from a rollover line and that particular number is not in your contacts list and is in the spam database.
The same thing is happening to me, but it's random and not limited to certain people. I'm with Verizon and have an S24+. Very frustrating to say the least, especially since I never had issues like this with my 22
