There is a Mobile Data button in the Quick Settings panal that turns the mobile data on and offā¦is it possible that you accidentally hit that button and turned off your mobile data?
If you don't use Wi-Fi, then contact your carrier. All things mobile calling/data related are carrier issues. It could be that cell service in your area was disrupted last night.
Have you contacted your carrier? You didn't use any punctuation. Are you saying the internet does not work either? Is internet or mobile not turning on? Did you accidentally turn on airplane mode? Did anything happen just prior to this condition appearing?
