One of the first things our travelers ask before arrival in Vietnam: “How do I get a SIM card or mobile data?”
Luckily, Vietnam has fast 4G nationwide (and expanding 5G in major cities).
Getting connected is simple, cheap, and flexible — whether you prefer a physical SIM card or a modern eSIM.

Where to Buy a SIM Card
- Airports (Noi Bai, Tan Son Nhat, Da Nang): Kiosks in arrival halls, quick setup in 5–10 minutes.
- City Mobile Shops: Official Viettel, Mobifone, and Vinaphone stores (offer better prices and more data package options).
- Online/Travel Agencies: Some agencies (Tonkin Travel) can arrange SIMs or eSIMs in advance for a smoother arrival.
Tips for Travelers
- Bring your passport: it’s required for SIM registration.
- Buy from official counters (avoid random street sellers).
- If you need tethering/hotspot, confirm the plan allows it.
- Check your phone is unlocked before arriving.
- For longer stays (>1 month), top-ups are easy via convenience stores.
FAQs
