eSIM (embedded SIM) cards are a relatively new technology slowly gaining popularity in various parts of the world, including Vietnam.

An eSIM is a digital SIM card embedded directly into a device, eliminating the need for a physical, removable SIM card.

Here’s some information about eSIMs in Hanoi, Vietnam:


eSIM support was still emerging in Vietnam. It may not have been as widely available as traditional physical SIM cards, but the situation might have changed since then. You would need to check with local mobile providers and retailers in Hanoi to inquire about the current availability of eSIMs.

To use an eSIM in Hanoi or anywhere else, you would need a device that supports this technology. Some popular smartphone manufacturers, such as Apple and Google, have incorporated eSIM support into their devices.


Activating an eSIM typically involves scanning a QR code provided by your mobile provider or setting up the eSIM profile manually through your device’s settings. The exact process may vary depending on the provider and the device you’re using.

Advantages of eSIMs:


With eSIMs, there’s no need to physically swap SIM cards, making it easy to switch between different mobile plans or providers.

Multiple Profiles

Some eSIM-capable devices allow you to store multiple eSIM profiles, which can be helpful for travelers who want to use different mobile plans in different countries.

Disadvantages of eSIMs:

Limited Compatibility

Not all devices support eSIM technology, so it may not be an option for everyone.
