I'm so confused. I live in London and I'm on the 3 network and I constantly have Roaming switched on. Is this correct? When I go away on holiday, if I go to one of 3's 'Feel At Home' destinations should I be turning Roaming off or leaving it on? Also, if I go on holiday to a destination that isn't a 'Feel At Home' place, should I be leaving Roaming on or turning it off?
