Hanoi Airport SIM Card: The Complete Guide for Tourists

Staying connected while traveling in Vietnam is essential for maps, transport apps, and keeping in touch. If you’re arriving at Noi Bai International Airport in Hanoi, one of the first questions is: Should I buy a SIM card at Hanoi Airport?

This guide explains where to buy, the pros and cons, alternative options, and tips to make sure you get the best deal.

After immigration and customs at Noi Bai Airport (HAN), you’ll see SIM card stores in the arrivals area. The main telecom providers are:

• Viettel – widest coverage across Vietnam
  
• Vinaphone – good data speed in cities
• MobiFone – reliable option for tourists
  

Most counters are open 24/7 and staff usually speak English. They will insert the SIM for you, register it with your passport, and ensure it’s activated before you leave.

1. Instant internet access – Use Google Maps, Grab, or WhatsApp right after landing.
   
2. Convenience – No need to search for stores in the city. Everything is set up at the airport.
   
3. Tourist SIM packages – Ready-made bundles (7–30 days) with large data allowances.
   
4. Multiple payment options – Cash (VND) and credit cards are accepted.
   

👉 If you value speed and ease, the airport SIM card is the fastest way to get online in Vietnam.

1. Higher prices – Expect to pay 30–40% more than in Hanoi city. Example:
   • City price: VND 150,000 (~US $6)
   • Airport price: VND 250,000–350,000 (~US $10–15)
2. Limited plan choices – Airport counters offer only a few tourist SIM options.
3. Possible waiting time – Long queues during busy flight arrivals.
4. Activation issues – Some travelers report SIMs expiring early or not working properly. Always test before leaving.

3. Use International Roaming
