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

Hello Chucky9177,


Thanks for asking the Apple Support Communities about Wi-Fi and cellular data.


Please start by ensuring your device is updated to iOS 14.6: Update your iPhone, iPad, or iPod touch - Apple Support


Next, please check all your settings here: View or change cellular data settings on iPhone - Apple Support


If you still have issues, please tell us the answers here:


Is this occurring with a specific line and eSIM? Using Dual SIM with an eSIM - Apple Support


Is this occurring in a specific area only? the same things that cause wireless interference can cause cellular interference: Resolve Wi-Fi and Bluetooth issues caused by wireless interference - Apple Support


Thanks.

Thank you for the reply,


I am running IOS 14.6 and have checked all the settings you refer to, they are all correctly setup. I am using a normal Nano-Sim on the Vodacom network in South Africa.


The problem occurs randomly when I move from any Wifi area onto my mobile data carrier (Vodacom). There is no warning or message and it shows that it has connected to 4G/5G, however no Whatsapp messages come through and I'm unable to access any apps requiring data.


I then have no choice but to restart the phone in order for it to reset and then it works fine.


Please help, I'm missing crucial messages and it's driving me crazy!
