Do we have any gurus on here? I don't know what the correct terminology is but when you have a mobile and it attaches to a local cell tower.
So just normal mobile fone operation.
My family uses an app that tracks we all are. So much easier than having to tell people where you are all the time!
Life360, it's called.
However, I appear to be the only one who regularly 'clocks in' to a mast 30-40 miles away? Admittedly, I did used to live around there and I work not too far from this area too but sitting in the house last night, the GF pipes up, 'you've just clocked in to the beach again!'
