So, lemme see now....
When your phone is 'on' and 'active', you may have a licence.
IF your phone is 'off' you may or may not have a licence.
IF your phone is on 'Flight Mode' of course you may have a licence,
IF you have a piece of paper in your wallet / folder / flight bag, then you DO have a licence...no matter how 'tatty' that piece of paper may be...
That's PROGRESS.
So....Wot's the advantage..??
