iPhone 13 mini won’t connect to carrier. Keeps saying no service

hello. My iPhone 13 mini just stopped connecting to my network and just says no service or searching. I’ve turned it on and off, checked all the settings and did all the steps. Nothing works. I took the SIM card out and put in a different phone and it worked fine. Put back in iPhone and nothing, it will still connect to Wi-Fi. So I did an update. Still nothing. Did a factory reset. Nada.

any help is appreciated. Thanks in advance
