How to Get a SIM or eSIM in Hanoi (2025 Travel Guide)

Landing at Hanoi's Noi Bai Airport and wondering how to get connected? Whether you're ordering a Grab to your hotel, checking into your Airbnb, or sharing your first bowl of phở on Instagram - having mobile data from the start makes everything easier. This guide covers where to buy a Vietnam SIM card for tourists, how to set up an eSIM, airport vs city prices, and insider tips for avoiding common pitfalls.

Quick Overview: SIM vs eSIM in Vietnam

Option 1: Buying a SIM Card at Hanoi Airport (Noi Bai - HAN)

If you're looking for the fastest way to get mobile data in Vietnam, the airport is your best bet. You'll find official SIM kiosks right outside the International Arrivals gate in Terminal 2. You'll find English-speaking staff, tourist-friendly SIM packages, and quick setup - just hand over your phone and passport.

Typical prices:

• Viettel: 10-15GB data, 30 days - around $10-$12
• Vinaphone: 7-10GB with call credit - about $8-$10
• Mobifone: 4-6GB data - from $6

Tip: Choose Viettel if you're planning to travel to remote areas like Sapa or Ha Giang - their rural coverage is the best.

Option 2: Using an eSIM in Vietnam

Got an iPhone XS or newer? Or a Google Pixel, Samsung Galaxy S20+, or similar? You can skip the physical SIM and install a Vietnam eSIM instead - super handy if you want to stay connected immediately without visiting a shop. No need to swap SIM cards, activate before or after you land, and it works instantly once set up.

Most of these are data-only, which is fine for most travellers using WhatsApp or Messenger. Activation is via QR code - takes 5-10 minutes.

Option 3: Buying a SIM in Central Hanoi

If you're staying in the Old Quarter or have time to look around, you'll find better deals than the airport by visiting a local mobile shop. Look for official Viettel, Mobifone, or Vinaphone stores, or reliable mobile phone shops (ask your hotel). Typical prices are 5GB-15GB for around $5-$9, and some plans include local calls and social media data. You'll need your passport, an unlocked phone, and cash is easiest. Avoid street sellers or market stalls - those SIMs may be pre-used or not properly registered.

How to Top Up Mobile Data or Call Credit

Once you've got your Vietnam SIM or eSIM: download the official app (e.g. My Viettel, My VNPT), then top up by card through the app or buy recharge cards at Circle K, VinMart, or any corner shop. Most apps are available in English and easy to use.

Do's and Don'ts

Do: bring your passport, make sure your phone is unlocked, buy from trusted shops or airport kiosks, choose the right plan for your trip length, test your SIM before leaving the shop, and consider a regional eSIM if visiting multiple Southeast Asia countries.

Don't: buy from street vendors, assume all plans have unlimited data, wait until you're in remote areas to sort a SIM, forget to scan your eSIM QR code while on Wi-Fi, or ignore the expiry date of your eSIM.
