Vietnam is the fastest growing internet market in Southeast Asia with over 50% household saturation of ADSL in urban cities. WiFi is freely available in all small hotels in HCMC. Paradoxically, some luxury hotels charge a connection fee. However, most restaurants and cafes in Saigon will freely give you a login password. Just ask. Once only an aromatic meeting place, HCMC cafes have morphed into internet connection hubs. Some Saigonese have even ditched the traditional office for a hooked-in café table. Facebook is expanding rapidly in Vietnam. There are nearly 10 million users, 70% of those are under 25. Although the social networking site is occasionally blocked by most ISPs for political reasons, you may be able to use a proxy server to gain access.
