Cellular Abroad offers two data options for Hong Kong. The first is a data only SIM card. If you have an unlocked smartphone or tablet, you can simply insert the SIM card into your advice and access mobile data. Alternatively, if your device is locked, doesn't have a SIM card slot or, if you have multiple devices, rent a mobile hotspot in order to access cellular data virtually anywhere in Hong Kong. A mobile hotspot creates your own private Wi Fi network that only you (and those that have the login password) can access.
