Vietnam eSIM Installation Guide: Step-by-Step Setup for Travelers & Expats

If you’re searching for the most reliable Vietnam eSIM installation guide, you’re in the right place! With the rise of eSIM technology, travelers and expats visiting Vietnam can enjoy instant connectivity without the hassle of traditional SIM cards. Whether you want fast data, local calls, or simply the flexibility to switch plans, eSIM makes it all possible—digitally. This guide will walk you through every step of the Vietnam eSIM installation process, from checking compatibility to activating your plan and troubleshooting common issues.

What is eSIM and Why Install One in Vietnam?

An eSIM (embedded SIM) is a digital SIM profile that works without the need for a physical plastic card. Supported by most modern smartphones (iPhone XR/XS and above, Google Pixel 3+, Samsung Galaxy S20+, and others), eSIM allows you to download a local Vietnam mobile plan simply by scanning a QR code. This process is fast, eco-friendly, and lets you keep your home SIM active for WhatsApp, banking, or SMS while using Vietnam’s top 4G/LTE networks.

Instant Activation: No waiting in line or visiting a shop. Install your eSIM before arrival or right after landing.
Dual SIM Ready: Keep your home number while using Vietnam data and calls.
Environmentally Friendly: 100% digital—no plastic waste.
Flexible Plans: Data-only, voice+data, or local number options.

Frequently Asked Questions: Vietnam eSIM Installation Guide

What if my eSIM QR code doesn’t work?

If you have trouble scanning your eSIM QR code, first check your internet connection and camera. Make sure the code isn’t blurry or cut off. Most providers can resend the QR code if needed—just contact their support (see below). Try cleaning your camera lens or increase screen brightness if scanning from a laptop. For stubborn issues, enter the eSIM details manually (settings usually provide an “Enter Details Manually” option).

How do I top up or extend my Vietnam eSIM?

Most providers, such as GoVnSIM and Airalo, offer an online dashboard or app where you can extend your plan, top up data, or buy new packages without re-scanning a QR code. Payment is secure and instant—perfect for longer stays in Vietnam.

Can I use my Vietnam eSIM and my home SIM at the same time?

Yes! Modern smartphones let you keep your home SIM active for calls, SMS, and WhatsApp while using your Vietnam eSIM for local data and calls. Just select which SIM handles mobile data in your settings.

Can I get a Vietnamese phone number with my eSIM?

Definitely. Some plans (like Vietnam eSIM with Phone Number by GoVnSIM) include a real local number for Grab, food delivery, and app registration—great for expats or anyone staying longer in Vietnam.

What if I delete my eSIM or change phones?

Keep your QR code email safe. If you change devices or delete the profile by mistake, contact your provider’s support to resend your eSIM. Some providers allow easy re-issuance; always check the terms before purchase.
