What Is Asian eSIM?

A Asian eSIM is a digital SIM profile that you install directly on your eSIM-compatible smartphone. Instead of buying and inserting a plastic SIM card, you simply scan a QR code and activate your mobile data plan online.

For the 3-day package, travelers can choose between two daily data options:

0.6GB per day for 3 days – ideal for light users
1.5GB per day for 3 days – perfect for moderate users

Each day’s data allowance resets every 24 hours during the validity period.

Why Choose the 3-Day Asian eSIM Plan?

Perfect for Short Trips

The 3-day Vietnam eSIM is designed for:

Weekend getaways
Short business trips
Quick island visits
Transit travelers in Southeast Asia

You get exactly the amount of data you need without overpaying for long-term packages.

Flexible Data Options: 0.6GB vs 1.5GB Per Day

One of the biggest advantages of this plan is flexibility.

Choose 0.6GB/day if you mainly:

Use maps and navigation
Send messages on WhatsApp or Messenger
Check emails
Light social media browsing

Choose 1.5GB/day if you plan to:

Use social media frequently
Upload photos and short videos

Browse heavily throughout the day

This allows travelers to match their data plan to their real usage.

Nha Trang

Many plans also support roaming across popular Southeast Asian countries, including:
