📝 Step-by-Step: How to Register Vietnam eSIM Phone Number (2025)

Follow these steps for a smooth eSIM registration process, whether you buy before your trip or on arrival in Vietnam.

1. 🛒 Choose a Trusted eSIM Provider
   • Pick an official partner of Viettel, MobiFone, or VinaPhone.
     ✔️ GovnSIM is a direct reseller for all 3 (no virtual numbers, all KYC-registered).
   • Tip: Avoid marketplaces or resellers who cannot guarantee a real Vietnamese number and local data speeds.
2. 📧 Receive Your eSIM QR Code
   • After purchase, you’ll get a QR code instantly by email or WhatsApp (no shipping needed).
   • If you have issues scanning the QR, ask the provider to send the LPA code (manual install supported on iOS/Android 13+).
3. ⚙️ Install eSIM on Your Device
   • Open your phone’s settings, select Mobile Data / Cellular > Add eSIM / Add Cellular Plan.
   • Scan the QR code or enter the activation code manually.
   • Wait 1–2 minutes for network activation. You’ll see Viettel, MobiFone, or VinaPhone as the new carrier.

4. 🔑 Register Your Passport/ID (KYC)
   • Vietnam requires KYC (Know Your Customer) for all SIM/eSIM activations.
   • When buying from GovnSIM, you upload your passport page during checkout or send it via WhatsApp/LINE/Email (encrypted & privacy compliant).
   • GovnSIM will register your info directly with the network (same as in-store registration).
5. ✅ Activate and Check Your Vietnam Phone Number
   • Once KYC is complete, your phone number is live – usually within 10 minutes (max 1 hour during peak).
   • To check your Vietnam number:
     Viettel: Dial *0#
     MobiFone: Dial *0# or *101#
     VinaPhone: Dial *110#
   • Your number starts with +84 (Vietnam country code).

📝 Real Example (July 2025): John (US traveler) landed in Hanoi at 8:00 AM, installed his Viettel eSIM from GovnSIM, completed KYC by uploading passport via WhatsApp, and had a working Vietnamese number (+84 98xxxxxxx) ready for Grab rides within 15 minutes.

🛠️ Troubleshooting: Common eSIM Registration Issues & Solutions

• ❌ eSIM Not Activating? Double-check that your phone is unlocked and supports eSIM. If the activation code fails, ask GovnSIM for a manual LPA code.
• ⏳ Stuck on “Activating” Screen? Switch Wi-Fi off/on, reboot your phone, and make sure mobile data is enabled. Activation usually takes 1–10 minutes.
• 🕵️ No Phone Number Assigned? Wait for KYC to be completed (GovnSIM usually within 10–15 mins). Check your number using the codes in Part 1.
• 📵 No Signal or Network? Try turning Airplane Mode ON and OFF. If you’re still offline, check APN settings (set APN to v-internet for Viettel, m-wap for MobiFone, m3-world for VinaPhone).
• 🛂 Can’t Register for Banking/Grab? Make sure your number is a true local SIM (starts +84), not VoIP. All GovnSIM eSIMs are fully KYC registered and accepted.
• 🔁 Changing phones? eSIM is single-device, but GovnSIM can re-issue a new QR code (one-time only, for security) if you lose or upgrade your device. Contact support for help.
