Holidaymakers and business travellers are finding it hard to grasp the pricing plans attached to wireless broadband use abroad, it has been suggested.
Alison Couper, communications director at Expedia, has explained that the varying charges which internet users incur overseas when using wireless can be "confusing".
This, Ms Couper said, was down to the discrepancy between the costliest and the least expensive services.
She commented: "Wi-Fi rates in airport lounges, cafes and hotels were high and confusing and in some cases varied up to 1100 per cent in a single destination.
"The varying rates mean that travellers have no standard model, which makes any comparison difficult."
A report from travel technology provider Amadeus, published in spring 2008, showed that 89 per cent of firms said that their travelling representatives sent emails using mobile devices, including laptops, on the move.
