Not working properly
I’ve had this phone for a little over a year and for some reason this past month it has been acting up. It says I have service, yet I can’t look things up, message, call, or do anything unless I’m connected to WiFi and even then it doesn’t really work. I have unlimited data. I know that it is not my phone plan because everyone else on the plan doesn’t have these issues. It’s making so I can’t do my everyday life because I can’t call or search things. I’m wondering how I get this fixed. I have an IPhone 11. Thanks for the help
iPhone 11, iOS 15
