Vietnam eSIM with Phone Number Plans: Step-by-Step & Local Tips for 2025
✅ Vietnam eSIM with phone number is now the go-to solution for international travelers visiting Vietnam in 2025. This guide gives you verified plans, actual pricing, and practical tips you won’t find on generic blogs. Let’s dive in!
📱 What Is a Vietnam eSIM With Phone Number?
An eSIM with phone number lets you activate mobile data and get a real Vietnamese number for calls, SMS, and app verification. Unlike data-only eSIMs, these plans allow:
- Receiving OTP codes for Grab, Zalo, banking, etc.
- Local call & text functions (some plans support outgoing calls/SMS)
- Mobile data for Google Maps, ride-hailing, and daily apps
Real-life tip: Without a local number, you cannot register most local apps or receive critical delivery/taxi calls.
🌍 Why Travelers Need an eSIM With Local Number in Vietnam
- 🏍️ App registration: Grab, Baemin, Shopee, and local e-wallets require a Vietnamese phone number.
- 🔒 Verification: Many hotels, banks, and transport services require local number for confirmation/OTP.
- 📦 Delivery services: Shippers will call you directly (and won’t use WhatsApp or international numbers).
Without a local number, you may miss out on key Vietnam experiences or face difficulties with ride-hailing, food delivery, or even hotel check-in.
💡 How Vietnam eSIM With Phone Number Works (2025 Update)
- Order a verified eSIM with phone number from a reliable provider like GoVnSIM (Viettel eSIM).
- Get a QR code via email – scan to activate eSIM on your device (iPhone, Samsung, Pixel, etc.).
- Plan activates with a Vietnamese phone number (+84), ready for calls, SMS, and data use.
- Use *0# to check your number after eSIM is installed in Vietnam.
Note: Each device can only install a QR code ONCE. If removed, it cannot be reused.
