About issuing SIM card should I get one from the airport or from elsewhere and what is the best telecom company for Internet coverage?
Doesn't matter unless you plan on going out to the sticks in which case Viettel would be the best.
Ok then thanks for the reply 😀
All my friends seem to prefer Mobifone or Viettel. Vinaphone sucks in their opinion.
When you arrival airport, you can buy VIETTEL sim card - cheapest one. Or you buy at local shop near your hotel will be cheaper. Around 5usd for 1.
