eSIM: Complete guide for travelers in Vietnam
- on Sep 19, 2024 By: Phuong Mai NGUYEN
eSIM technology is integrated into smartphones, tablets, and laptops, allowing users to connect to cellphone networks by purchasing data plans directly from their devices, eliminating the need for a physical SIM card.
For those planning a trip to Vietnam, this article will explain in detail how to use eSIM while traveling in Vietnam.
What Is eSIM and How Does It Work?
eSIM, or "embedded SIM," is a virtual SIM card technology integrated directly into compatible devices. Unlike traditional physical SIM cards, eSIMs are activated remotely without needing to be inserted into the device.
Functioning as an integrated microchip, eSIM stores your SIM card information directly on your mobile device. When you purchase a data plan or phone package, the information is transmitted to your mobile device via a wireless connection and stored on the eSIM. This setup enables you to connect to mobile networks and access the Internet, make calls, or send text messages.
What's great about eSIM is that it lets you buy local data plans and phone packages directly from your mobile device without having to buy a physical SIM card at a point of sale. This can be particularly useful when you're traveling abroad and want to avoid high roaming charges. Additionally, eSIM is easy to activate and configure, making it convenient to use.
Keep in mind that eSIM is not yet supported by all mobile operators and is not yet compatible with all mobile devices. Before purchasing a data plan or phone package for your eSIM, make sure your device is compatible and that the mobile operator supports this technology.
Advantages of eSIM for travelers in Vietnam

- Seamless carrier switching: With eSIM, you can effortlessly switch between operators without the need to physically swap SIM cards, providing flexibility and convenience.
- Time-saving: Purchasing and activating an eSIM data plan can be done directly from your device, eliminating the need to visit a sale point and saving you valuable time.
- Efficient mobile plan management: eSIM allows users to store multiple mobile plans on a single device, making it easy to manage and switch between them as needed.
- Better security: Unlike physical SIM cards, eSIMs are integrated into your device, thereby reducing the risk of loss or theft and ensuring the protection of your personal information.
- Cost-effective travel: By purchasing local eSIM data plans, you can avoid expensive roaming fees, making eSIM a cost-effective option for staying connected while traveling.
