What is the problem and how do I fix it please ?
I'm not an iPhone user but if I was the first thing I would do would be to check in the IOS settings on the phone to make sure that your email app is allowed to use cellular/mobile date. IOS allows you to specify for each app whether or not it can use mobile data. It sounds as if your email app has been set to only use wifi.
Check this link https://support.apple.com/en-gb/guide/iphone and go to the bottom of the page to "Set whether cellular data is used for apps and services"to see how to do that.
If it's not that then I'm stumped I'm afraid.
