Here’s everything you need to know about using the internet, Wi-Fi, and phone services in Vietnam before you arrive.
📶 Internet & Wi-Fi in Vietnam
You’ll be pleasantly surprised by how easy it is to access the internet in Vietnam.
- Free Wi-Fi: Nearly all hotels, cafés, and restaurants offer free Wi-Fi. Even small guesthouses and local coffee shops often provide a reliable connection.

📱 Buying a Local SIM Card in Vietnam
For the best experience during your trip, purchasing a local SIM card with mobile data is highly recommended. Vietnam’s mobile networks are reliable, affordable, and widely available.
Major Mobile Network Providers
- Viettel – Best overall coverage, especially in rural or mountainous regions.
- Mobifone – Strong network in major cities and tourist destinations.
- Vinaphone – Reliable and easy to find at airports and convenience stores.
Where to Buy
You can buy a SIM card easily upon arrival at Vietnam’s international airports (Hanoi, Da Nang, Ho Chi Minh City) or at authorized mobile stores in any city. Remember to bring your passport, as registration is required for activation.
Typical Prices & Packages
- Data packages: from 50,000 VND (≈ $2 USD) for 1GB.
- Calls: around 3,000–6,000 VND per minute for international calls.
- Text messages: 500–2,500 VND per SMS.
Most SIM cards offer 4G or 5G speeds and can be topped up easily at any convenience store or online.
🌍 Making International Calls
Making direct international calls from Vietnam can be expensive, so most travelers prefer using internet-based apps like WhatsApp, Skype, Viber, or Facebook Messenger. These work perfectly with local data or Wi-Fi connections.
If you ever need to make a traditional international call:
- Vietnam’s country code: +84
- To call Vietnam from abroad: 00 + 84 + [area code without 0] + [subscriber number]
- To call abroad from Vietnam: use 00 + [country code] + [number]
🏞️ Coverage in Remote Areas
Vietnam’s mobile network is extensive, but there are still some remote regions—such as deep mountain areas in Ha Giang, Sapa, or Pu Luong—where signal strength can drop. However, for most destinations including cities, beaches, and rural towns, you’ll have good mobile data coverage.
💡 Travel Tip
To make your trip even smoother:
- Activate international roaming only as a backup, since it’s usually more expensive.
- Always keep your SIM card packaging and phone number note for recharges or support.
- Use offline maps (like Google Maps Offline) when traveling in rural regions without a signal.
✅ Final Thoughts
Staying connected in Vietnam is simple, fast, and affordable. With free Wi-Fi almost everywhere and cheap mobile data plans, you’ll have no trouble sharing your Vietnam adventures in real time. Whether you’re exploring the vibrant streets of Hanoi, cruising through Ha Long Bay, or trekking the northern mountains, reliable internet keeps you connected every step of the way.
