From my travel experience, Internet is really saving awkward foreign travellers bunch of hassle. So, here come the time-saving tips on how to use Internet on your smart phones (iPhone, Blackberry, any phone that have 3G function works).
Once you arrive in Vietnam, find any phone-card shop (wherever you see a sign listing all kinds of carriers’ names, must be it). Ask for Vinaphone SIM pack. The credit you get on the first charging is always at least double, sometimes triple the amount you pay. Depending on your stay, pick suitable kit. As of July 2010, for a week, I suggest the 180,000VND (which get you 360,000 VND credit). More on SIM pack tip later, at the footnote.
Compose a message with content “GPRS ON” (without the quote), send to 333 or 888.
Compose a message to send to 888, with content as listed down here, according to your usage
||10,000 VND/30 days
||25,000 VND/30 days
||50,000 VND/30 days
||300,000 VND/30 days
That’s it! Enjoy Internet on the go!
Note on SIM: As mentioned above, first charging will get you double/triple credit, unfortunately it doesn’t apply to recharge. So if you don’t really care about your phone number, after using up credit, just ditch your SIM and buy a new one.
