A new survey conducted by retailer Carphone Warehouse has found that a majority of Britons have limited or no knowledge about data roaming charges.
According to a survey of more than 2,000 customers, only six percent people were aware about the per mega-byte rate while travelling abroad.
The company also said that only 11 percent customers actually bothered to check the data roaming charges before they go for a trip abroad. Predictably, around 81 percent of the customers incur a bill of approximately £100 more than normal, due to data roaming charges.
Carphone also revealed that the use of social networking platform such as Twitter and Facebook while travelling abroad was the primary reason behind large data roaming costs.
Highlighting the rise in popularity of web enabled Smartphones, Carphone informed that 85 percent of the contract phones it had been selling were Smartphones.
“We've seen a real increase in Smartphone users over the past year," Carphone Warehouse UK managing director Matt Stringer said in a statement.
"However, even though adoption is high, the findings highlight the potentially high costs associated with using Smartphones abroad... Data users should keep a look out for Wi-Fi spots where they can connect to the internet without using the local 3G network", he added.
