Vietnam eSIM Guide 2025: Compare, Install, and Stay Connected the Smart Way
Vietnam eSIM Guide 2025 — your complete, realistic handbook for travelers and expats who want instant data, reliable coverage, and zero airport hassle. This guide explains everything: how eSIMs differ from physical SIM cards, which phones support them, how to install yours, and where to buy the best-value plans in Vietnam.
📶 What Is an eSIM (and Why It Matters in Vietnam)
An eSIM is a digital SIM built into your phone — no need for plastic cards or store visits. You activate it by scanning a QR code, then connect instantly when you land. Perfect for short stays, digital nomads, or anyone tired of airport SIM counters and paperwork.
- Instant setup: Activate in 2–5 minutes via QR.
- Nationwide coverage: Runs on Viettel, MobiFone, or VinaPhone networks.
- Local number: Required for Grab, Zalo, Shopee, and other Vietnamese apps.
- Safe & convenient: No risk of SIM loss or cloning.
💡 eSIM vs Physical SIM: Which Is Better for You?
| Criteria | eSIM | Physical SIM |
|---|---|---|
| Setup | Scan QR, instant activation | Must visit a counter |
| Passport required | ❌ Not needed | ✅ Required |
| Risk of loss | None | Possible |
| Tethering | Yes | Yes |
| Availability | Online stores like GoVnSIM | Airport kiosks, shops |
| Best for | Travelers & expats | Locals, long-term users |
Verdict: If you’re visiting Vietnam for a few days or weeks, eSIMs save time and avoid tourist overpricing. Physical SIMs still suit those needing long-term top-ups or dual-SIM phones without eSIM support.

🛒 Where to Buy a Vietnam eSIM
✈️ Option 1 – Airport Counters (30–40% more expensive)
Convenient but pricey. Sales reps may push high-margin plans, and English support varies. Ideal only if you didn’t pre-order online.
🏙️ Option 2 – City SIM Shops (20–30% higher)
Better prices than the airport but still require your passport and often take 15–20 minutes to register. Some smaller shops only accept cash.
🌐 Option 3 – Online Purchase (GoVnSIM.com)
Most convenient for tourists. Choose your plan, receive the QR instantly by email, and activate when you land. English support available 24/7, and prices are typically 30–40% lower than airport counters.
Example: A 10-day MobiFone eSIM with a Vietnam number costs ~$6.9 on GoVnSIM, compared to $10–11 at Hanoi Airport.
⚙️ How to Install & Activate Your eSIM
- Purchase your eSIM online from GoVnSIM.com.
- Receive your QR code by email.
- Open Settings → Mobile Data → Add eSIM.
- Scan the QR code.
- Label it “Vietnam eSIM”.
- When you land, turn on Data Roaming.
- Restart your phone — you’re online!
💡 Pro tip: Install the eSIM 1 day before departure but activate only after landing to avoid premature data start.
