I recently got a newly refurbished unlocked S23. It was working fine, sending and receiving calls and texts normally, but then a couple days ago I took it out of my pocket and it said I was locked out of my network and needed an MCK because of too many unlock attempts. It did not allow me to try to unlock it, only dismiss the notif. I can still access the rest of my phone, but I cannot make or receive any calls. I tried checking available networks, and it listed Verizon, AT&T, T Mobile, etc. I had been using a physical sim with visible, but suddenly it started saying that it couldn't be used because it was locked to a different carrier, but I can't find any indication of carrier locking besides that. I tried switching to AT&T, but I still have the same problem. When I try resetting or restarting, it says sim invalid whether it's esim or physical. When I try searching available networks, it just gives me an error and stays on automatic network select. All sims just say unknown carrier and number. I have tried network reset, factory reset, nothing works. Please help?
