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

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!
