Hi guys, I have another question.
I tried to check online but the websites are in Viet.
Any advice about how much a prepaid SIM card with unlimited Internet (for a few days) would cost?
Wikitravel says it will just cost about 50 000 Dong on Viettel for unlimited 3G - which is VERY cheap.
Is that true? Where can I get these SIM cards? Convenience stores (if they are common in Hanoi?)?
