iPhone 13pro max no sim available

I have this “no sim available” error popping up on my phone for a few days now. My iMsg and FaceTime are not working anymore, and they obviously did work up until an hour ago. Ive done everything, talked to vodafone … useless, restarted phone, etc etc… nothing works. I need help cause every time this error comes up, I have no way of contacting anyone. Normal phone call dont work anymore either.
