I cant find the option for transffering contacts from simcard in the iphone 12. solution?

I am trying to find a way of retaining my contacts even if i am transferring from an android to an iphone. Isn't there a way this should be easy to do? I cant even copy contacts from my simcard. Or atleast, i cant find that option. Only option i find is *icould* which ofcourse does not have my contacts since i had an android
