📶 Where to Buy SIM Card in Vietnam: The 2025 Guide for Travelers
Where to buy SIM card in Vietnam is a top search for visitors planning their trip. Having mobile data and a Vietnamese phone number is essential for using Grab, Google Maps, ride-hailing, or simply keeping in touch with friends and work. This guide covers all the best places to get your SIM card—airport, city centers, convenience stores, and eSIM online—along with current prices, real experiences, and pro tips to make your Vietnam trip seamless.
🛬 Buying a SIM Card at Vietnam Airports
The fastest and most popular way to get connected is at the airport right after landing. All major international airports in Vietnam (Hanoi, Ho Chi Minh City, Da Nang) have official SIM card booths just after customs.
- 📍 Location: Arrival halls, next to baggage claim/customs exit
- 🟩 Providers: Viettel, Mobifone, Vinaphone – official counters only
- ⏱️ Activation: 5–10 minutes (show your passport, get registered, test on the spot)
- 💳 Payment: Cash (VND, USD) and cards accepted
💸 Airport SIM Card Prices (2025)
| Provider | Data / Day | Calls | Validity | Price (USD) | Phone Number |
|---|---|---|---|---|---|
| Viettel | 6GB | 300 min (local) | 30 days | $18–22 | Yes |
| Mobifone | 6GB | 500 min (on-net) | 30 days | $18–20 | Yes |
| Vinaphone | 5GB | 300 min | 30 days | $17–20 | Yes |
*Accurate as of July 2025, all SIMs include a local number and instant activation. Airport prices are typically 10–20% higher than downtown but much more convenient for new arrivals.
🏙️ Buying SIM Card in City Centers
You can also purchase a SIM card in the downtown areas of major cities like Hanoi, Ho Chi Minh City, Da Nang, Nha Trang, and Hue. Here’s what you should know:
- 📍 Where: Official carrier stores, large electronics shops, and select travel agencies
- 💰 Price: $9–15 for similar plans (often a bit cheaper than airport)
- ⚠️ Beware of: Unauthorized street vendors or small shops—risk of fake/reused SIMs
- 🗣️ Staff: Limited English in some local stores, official stores have better support

🏪 Buying SIM Card at Convenience Stores
In 2025, some major convenience stores in big cities (Circle K, Vinmart+, FamilyMart) also sell SIM cards from official networks. However:
- 🛒 SIM types: Mostly data-only or short-term tourist SIMs
- 📝 Registration: Staff will ask for your passport
- ⏳ Process: Sometimes takes longer than at the airport or carrier store
- 🗣️ English: Support may be limited
Always request an official SIM, check activation before leaving the store, and never buy from unlicensed street kiosks.
🌐 Buying eSIM Online – Instant Activation
For travelers with eSIM-compatible phones (most iPhones after XS, Google Pixel, Samsung S20+), buying an eSIM online is the most convenient option:
- 🛒 How: Purchase from a trusted provider (like GoVnSIM)
- 📧 Activation: Receive a QR code via email, scan to activate instantly
- 🚀 Benefit: Ready before you land, skip all lines at the airport
