Do you still use a landline at home, or do you rely completely on your cell phone?
On the rare occasion I make a phone call (I really do not like phones) then I use the landline.
I only have a mobile for 'emergencies' and for the last couple of years the only use it gets is to turn it on once a month to make a quick call to our home number in order to keep it activated and I charge it once a month. Otherwise is lives in the drawer of one of my bedside units. It's ancient (by mobile phone standards)
