Back in the days when we went to work, my phone would cling on to the weak office wifi signal from the pub over the road. Quite often turned it off and then used loads of data at home without realising.
Also, previous galaxy S10 used to always try to connect to the o2 wifi in sainsburys. Turned it off if I needed to use internet while there. S21 doesn't, thankfully.
