Cellular Data Usage When Cellular Data is Turned Off?

I have an iphone 12 Pro on 14.5.1. I noticed that my cellular data usage was way above normal. Checked and saw that my phone was recording data usage when I was in my apartment on wireless. Wireless is working fine for other devices. So, yesterday I turned off all celluar data. This morning I see that the phone used cellular data at 1:15 am while I was asleep. Any ideas on what could be doing this and how to fix it?

“Wifi assist” should be turned off as it will override the cellular off setting.

Make sure you turn cellular off in settings rather than the control centre as the latter resets at 5am
