🇮🇳 Introduction: Why Indian Travellers Need Reliable Mobile Data in Vietnam

Vietnam has rapidly become one of the top travel destinations for Indian tourists. With direct flights from Delhi, Mumbai, Bangalore, Chennai, and Kolkata, plus affordable visa options and a growing love for Vietnamese food, beaches, and culture — more than 500,000 Indian visitors are expected to travel to Vietnam in 2025.

But the moment most Indian travellers land in Vietnam, they face the same issue:
👉 No mobile internet,
👉 No Grab taxi booking,
👉 No Google Maps,
👉 No WhatsApp or Instagram,
👉 And no way to contact their hotel or driver.

Reliable internet access is essential for:

  • Navigating the streets of Hanoi and Ho Chi Minh City
  • Using Grab for transportation
  • Booking tours and hotels
  • Currency conversion apps
  • Translation apps
  • Video calls and social media
  • Remote work or business trips

That leads to the question:
“What is the best way for Indian travellers to get stable mobile data in Vietnam — eSIM, SIM card, or roaming?”

This comprehensive guide will help you choose the best and most cost-efficient connectivity option, especially focusing on Mobifone Vietnam eSIM, one of the strongest networks for travellers.

📱 Chapter 2: Mobile Data Options for Indian Travellers — Full Comparison

Indian visitors have 3 main ways to get mobile data in Vietnam:

Option 1: India Roaming Plans (Jio, Airtel, Vi)

Most Indian carriers offer roaming, but it is the most expensive option and gives very little data.

🇮🇳 India Roaming Costs (2025 Estimates):

Carrier Data Validity Average Cost (INR)
Jio Roaming 1–2GB 5–7 Days ₹2,999–₹5,000
Airtel Roaming 1GB 5 Days ₹3,500–₹4,999
Vi Roaming 1GB 7 Days ₹3,000–₹4,200

❌ Drawbacks:

  • Extremely expensive
  • Limited data
  • No hotspot
  • Slower data speed
  • Risk of bill shock

✔️ Who should use roaming?

❗ Only business travellers needing very short coverage.

For everyone else, roaming is a bad deal.

Option 2: Local SIM Card (Buy After Arrival)

You can buy a SIM card at the airport or mobile store.

📌 Problems for Indian travellers:

  • OTP banking problems after swapping SIM

✔️ Who is it good for?

Travellers staying >1 month, but ONLY if they don’t need their Indian SIM active.
