You can open Settings > Cellular - Cellular Data and look at the list of everything which used data and how much.

What did your mobile data provider tell you when you contacted them?

They were not very helpful and said to contact apple and get a print out of what was being downloaded. Is there a way to print out the mobile data? From what I could see, there was nothing that showed unusually heavy usage and I turned off the mobile hotspot and non-essential notifications. Even I spent most of the day on WiFi it was unusually high mobile data, which is puzzling. I added more mobile data to increase my allotment and in 2 days went through almost 6gb, while most of the day, I was on WiFi.
There is no print out, you do that by logging into your cellular data account on a web browser and view it there.
Follow the advice given by lobsterghost1.
Same problem. My son’s iPhone 17 pro just dumped 100gb in an hour just sitting on the table. 3 days before it dumped 27, then 24 from his pocket. He doesn’t stream. All settings are set to reduce data usage. All apps closed. Nothing in usage for this volume of data. Carrier said it’s an apple think on iPhone 17s. Going to the shop tomorrow

Your carrier told you to contact Apple to get a print out of the cellular data used on your iPhone????? You need a new carrier. That is one of the dumbest responses I think I've ever heard a carrier provide. How would Apple know what data you consumed on your iPhone? Apple has NOTHING to do with cellular services at all.
I told you above how to check what you used in data on your iPhone. Did you look where I recommended you look?
iPhone Pro 17 mobile data usage increases unexpectedly
