Nearly two-thirds (62 percent) of UK mobile phone owners are confused by the term data roaming, says GoodMobilePhone.co.uk.
Research of 1,680 Brits that have a mobile phone revealed just 26 percent knew the phrase refers to the ability to access internet services abroad through a mobile network, while more than half (52 percent) thought the term means accessing emails whilst on the move, for example when walking around town.
Furthermore, 56 percent did not know the exact meaning of 3G, while 47 percent were confused over the acronym MMS. Bluetooth stumped 28 percent of those surveyed, while 43 percent weren't sure what Wi-Fi actually means.
More than four in five (81 percent) also said they were not given enough advice on using all aspects of the handset when they purchased the device from their network provider.
"Data Roaming can be a bit of a minefield, and there are always horror stories of people running up hundreds of pounds on their bill whilst abroad, because they failed to take into account the increased charges that can apply when overseas," said Mark Owen, Managing Director of GoodMobilePhones.co.uk.
"It's important that you make yourself aware of the extra charges that can apply before going abroad, and ensure that you take the necessary precautions to avoid racking up a huge bill! If you are confused about data roaming, there are lots of easy to digest guides on-line."
