No service

My iPhone 8 says no service but I do have Wi-Fi. This this is not the first time it has happened and it seems to me that the last time it happened it worked after I took the Sim card out and replaced put put it in again that didn’t work this time and I miss seems like I inadvertently do this somehow when I go on my Settings and I touch something I’m not supposed to or any ideas on what that might be?
