Beware of Unexpected Mobile Data Roaming Charges when Travelling Abroad during Festive Holidays

The Office of the Communications Authority (OFCA) today (17 December 2018) reminded consumers to be cautious about the use of mobile data roaming service when travelling abroad during the festive holidays so as to avoid incurring unexpectedly high mobile data roaming charges.

"Nowadays, many consumers travel with mobile devices such as smart phones and tablets. Consumers should be mindful that the charges for accessing mobile data roaming service outside Hong Kong are in general much higher than the charges for local mobile data usage. Downloading of large files/video clips, video streaming, access to mobile online games or automatic update of applications (apps) may also consume unexpectedly large volume of mobile data and result in hefty charges," a spokesman for OFCA said.

"At present, some operators will automatically activate the data roaming service for their customers. If consumers do not need the service, they should contact their operators to deactivate it so as to avoid using the data roaming service inadvertently.

Consumers should pay extra attention when responding to such messages or clicking the hyperlinks provided therein, as mobile data connection may be activated by such an act and data roaming charges would be incurred as a result," the spokesman added.
