person icon on home screen next to 'time' what does it mean? - iPhone 15 never had it before

I have 'small person' icon next to the 'time' on my iPhone 15, and at 12 o'clock on my Series 8 Watch. I have never seen them previously. When I bought the watch I was with a different ISP and different Phone Carrier. I am now with Vodafone. Can anyone explain this please. I have checked all the Apple icons available on the watch, and the iPhone, plus I've checked the Vodafone advertising pages, but nothing shows me an answer. It's driving me nuts. Please can someone put me out of my misery.
