✈️ Introduction: Staying Connected While Traveling in Vietnam

When visiting Vietnam — a country full of rich culture, breathtaking scenery, and vibrant cities — staying connected to the internet is essential for a smooth travel experience. Whether you’re posting photos of Ha Long Bay, navigating Hanoi’s chaotic Old Quarter, or working remotely from Da Nang’s beaches, a stable internet connection makes all the difference.

In this 2025 guide, we’ll explore the best Internet options in Vietnam for tourists, comparing WiFi, SIM cards, and eSIMs, and highlighting the best ways to access 4G/5G Vietnam coverage anywhere you go.

🇻🇳 Internet Infrastructure in Vietnam

Vietnam has one of Southeast Asia’s fastest-growing digital networks. Over 70 million active internet users and strong investment in 4G/5G infrastructure mean that tourists can enjoy excellent connectivity almost everywhere — from big cities to rural villages.

🛰️ Main Internet Providers in Vietnam

  • Viettel – Largest national coverage, especially in mountainous and rural regions.
  • Mobifone – Reliable in major cities like Ho Chi Minh City, Da Nang, and Hanoi.
  • Vinaphone – Strong network and stable speeds, ideal for urban travelers.

All three carriers now provide 5G coverage in key cities, and 4G almost nationwide.

🌐 Internet in Vietnam for Tourists — Overview

When arriving in Vietnam, travelers can access the Internet in three main ways:
