Hi weiss.clayton.t,
When you are connected to 4G, does this problem appear?
Do you have landline phone or another cell phone? So you may call your number and check under 4G.
We would suggest you check Contacts > Three dots on the top right > Settings > Call blocking & block list, make sure not to enable "Block numbers not in contacts" or "Block calls from hidden numbers".
Thank you 🙂
