Iphone12 pro max signal bar is empty

Ive been using the phone since april 2021, everything was fine til yesterday the signal bar is empty. I thought it has something to do with the carrier so today i tried to put the sim card in the other phone and the signal bars were full, the cellular was working. When i put the sim card back into my iphone 12 it doesnt work again, the signal bars are empty and i cant make or receive phone calls but i can use the internet data and wifi. Does anyone know how to fix this without doing the factory reset? Thank you!

iPhone 12 Pro Max, iOS 14
