Two out of three holidaymakers are risking high overseas phone charges by leaving their mobile switched on, according to a survey.
Mobile users are charged not just for making and receiving calls but also each time a voicemail message is left and each time a message is picked up.
And more than one in four Brits (43%) has got an expensive phone bill on their return from holiday, says the uSwitch.com survey of 1,310 UK adults.
The survey, carried out last month after the introduction of new EU pricing guidelines, found just 4.5% of holidaymakers protect themselves from charges by turning off their phone and keeping it off until they need to make a call.
Two out of three people (66%) switch on their phone without even intending to use it, with half of those having it turned on most of the time.
