Internet - Telecommunications in Vietnam
Vietnam currently has the most dynamic Internet market in Southeast Asia, with over 50% of households having ADSL in urban areas. Cafes, a friendly meeting place for Vietnamese people, have turned into Internet connection centers and passwords to access the wifi are indicated almost everywhere. Some coffee chains offer you a password for a short-term connection and after a set time, you must order again to obtain another password. Most cafes and restaurants allow you to log in unlimited upon arrival. Access to social networks such as Facebook, Twitter, …is as often as possible.
The postal system in Vietnam is quite reliable, but not very fast. If you want your package to be delivered quickly, several postal companies are available. Do not seal parcels before bringing them to the post office, as you are sometimes asked to show them before weighing and billing the parcel. DHL and FedEX services are also available in Vietnam. If you plan to receive a package, make sure the company follows the package for the entire journey. To send a postcard costs about 20 000 VND for abroad.
The Vietnam network is GSM compatible and works with most operators. You can purchase a local SIM card from VND 100,000. The most popular suppliers are Mobifone, Viettel and Vinaphone, and their rates are very good. 3G service is generally available in cities and prepaid plans are cheap. The 4G is on the road to rapid development.
With 1.3 cellphone per person in Vietnam, finding a mobile phone store is childish! Cases, chargers, screens for the latest smartphone are cheap. Remember that almost all of these accessories are off-brand and may not be of the best quality.
Stores also offer prepaid SIM cards for local phone calls - and they're probably a lot cheaper than what you're used to at home, so consider switching to a local prepaid number during your stay.
