iPhone 12 Pro Not switching between Wifi and Cellular data
I have recently purchased a new iPhone 12 Pro. The problem is that when I leave a Wifi area like my home or office the phone says that it has switched over to cellular data however it gives me an error claiming that I'm not connected and I must switch Mobile data on.
I have to restart the phone before it will use the Vodacom mobile network. I can still receive and make calls but anything data related won't work.
Any help?
iPhone 12 Pro, iOS 14
