With the advent of the fourth generation (4G) mobile communications technology, consumers find it increasingly attractive to get their hands on 4G mobile devices (smartphones, tablets, USB dongles, smart cameras, etc) and subscribe to the much faster 4G services (also known as Long Term Evolution (LTE) services).
While charges of other telecommunications services have fallen drastically over the past decade, those for Mobile Voice Roaming Services (MVRS) remain at relatively high levels. Consumers may consider using some more affordable substitutes for MVRS when travelling outside Hong Kong.
The penetration of mobile service in Hong Kong is one of the highest in the world. There are some safety precautions that you should pay attention to when you use your mobile phones, tablet PCs and other mobile communications devices.
If you want to avoid being connected to the more expensive International Direct Dialling (IDD) service using "001" as the access code , every time you make IDD calls overseas, you must key in the access code that you prefer or you can store the overseas telephone numbers with the access codes in the "phonebook" of your telephone / handset.
