Discover how to set up and activate eSIM on iPhone, Samsung, and Google Pixel devices while traveling in Vietnam. All you need is the QR code or activation details provided by your eSIM supplier, and the process can be completed within 3-5 minutes.

Once you’ve purchased your eSIM, you’ll receive an email containing your eSIM profile, including a QR code, SM-DP+ Address, Activation Code, and important usage instructions.

Follow this step-by-step guide to easily install and activate your eSIM. This tutorial is not only for eSIMs from Simgo.vn (a Adsdigi.com member) but also compatible with eSIMs from global providers.

In this guide, you’ll learn:

  • What you need to prepare before installing an eSIM
  • Step-by-step instructions for installing an eSIM
  • How to activate your eSIM for use in Vietnam

Important Tips Before You Begin:

  • The eSIM setup process usually takes just 2-3 minutes.
  • If you’re using a 5G-compatible device with a data-only eSIM for traveling in Vietnam, you might need to switch your eSIM settings to 4G/LTE by disabling 5G for optimal performance.

I. Preparation Before Installing an eSIM:

  1. Ensure you have a carrier-unlocked device that is compatible with eSIM technology. You can refer to our updated list of supported devices for confirmation.
  2. A stable WiFi connection is essential for a smooth setup.
  3. Gather the eSIM details provided by your eSIM provider, including the QR code, SM-DP+ Address, and Activation Code.

II. Different Methods to Install an eSIM

There are two main methods to install an eSIM, regardless of your phone’s brand or model:

  1. Using a QR Code: This is the quickest and simplest method, making it the default option for most users.
  2. Manual Entry: If scanning the QR code isn’t possible, you’ll need to manually input the eSIM details provided by your eSIM provider.

While the overall eSIM installation process is quite similar across devices, the specific instructions, menu placement, and terminology may differ depending on the phone’s model and operating system version.

This guide focuses on the installation process for iOS devices (e.g., iPhones) and Android devices (e.g., Samsung and Google Pixel phones). For other phone brands, you can follow a similar approach.

Let’s dive into the step-by-step process for installing an eSIM on your device.

Tips Before Installing an eSIM:

  • For iPhones with iOS versions older than iOS 16: Print out the QR code or have it accessible on another device, as you’ll need to scan it during the installation process.
  • For iPhones running iOS 17 or later: Simply download the QR code image and upload it directly for scanning, making the process more convenient.
  • Take note of the SM-DP+ Address and Activation Code ahead of time. This information will be crucial for manual setup in case scanning the QR code isn’t possible.
