iPhone 14 pro max shows full bars and 4g, but can’t connect using cellular data

Got my iPhone 14 pro max yesterday, after setting it up I inserted my sim and everything seems fine, it says I’m connected to my carrier and I have full bars 4g. But when I try to use my 4g there’s no connection, pages won’t load, weather app says no connection. I have tried turning it off and back on, toggling airplane mode, resetting network setting, removing and re inserting the SIM card, but nothing changes. When I get home I’ll try a different SIM card and see if it works. Has anyone else experienced this and if so fixed it?
