Nowadays more and more consumers use mobile data roaming service when traveling abroad. As roaming charges are much higher than domestic rates, consumers may incur exorbitant data roaming charges as a result of inadvertent use of the data roaming service. This has fast become a subject of concern.
In order that consumers may avoid unnecessary billing disputes with their mobile service operators and financial loss, we are issuing this consumer alert to provide the public with tips on smart use of mobile data roaming services.
In general, mobile data services (for both local and roaming services) can be activated by web browsing and usage of certain software applications on your mobile handset. Examples are sending and receiving e-mails, using instant messaging, visiting websites for social networking and video streaming. If you use a notebook computer equipped with mobile data modem outside Hong Kong, you may also trigger the usage of mobile data roaming service.

Some mobile service operators are providing customers with a day pass i.e. a flat-rate data roaming daily plan (typically less than HK$200 per day) for data usage in certain destinations. You should take note that most of these chargecapped data usage packages (or discount rates) are only applicable to designated destination(s) and/or network(s). Thus, you should ensure that the daily pass purchased applies to the destination and you are always logged onto the designated network(s) in the destination. Otherwise, regular data roaming charges which are at a much higher level will be incurred.
Furthermore, if your handset is configured to "automatic" network selection, you may encounter the problem of "network switching". This will occur when the signals of the connected network has become weakened. Your handset will then be connected to other non-designated networks which have stronger signals. To avoid additional data roaming charges arising from such "network switching", you should configure your handset to manual network selection so that the connection will be confined only to the designated network(s). The manual network selection procedures may vary with different handset models. In general, you may follow the steps below:
If you choose to use a day pass, you should beware of the service activation and cut-off time. In general, the service will be activated only after confirmation has been made by the customers via a short message upon arrival at the destination. You therefore need to clarify with your service operators whether the service will be activated immediately or after a lapse of time upon making the confirmation.
The definition of "a day" may also vary. "A day" may be counted based on the local time (00:00 – 23:59) of Hong Kong, or that of the destination. The daily charges may also be counted on per destination basis. For example, if you use mobile data service in the United Kingdom in the morning, then you travel to France in the afternoon, you will be charged twice for traveling in the two countries in the same day. To avoid unnecessary disputes, consumers must clarify with their service operators how the charges are calculated.
