Quality of the Internet access
Halong Bay’s free wifi only offer free access to some basic information pages (mostly belong to the government). Besides, after a few years, the network now no longer work well and is not covered the bay but only mainland. So to address the problem, on land, most of the hotels, hostels, restaurants offer their own free wifi for guests.
On the sea, almost all the cruises in Halong Bay offer free wifi, especially luxury cruises. However, just like any other places in the world, the signal on sea cannot be strong like on mainland, even for the mobile phone signal. So wifi or 3G seem to be useless most of the time onboard. Still, wifi can be used, works best when you are near the modem, normally in public areas like restaurant and reception area of the cruise. Wifi will be weaker when the cruise is moving and going through high islands.
