eSIM with Unlimited Data in Vietnam

An eSIM (embedded SIM) is a digital SIM card that can be installed directly into your smartphone or other mobile devices. It is an alternative to the physical, removable SIM card you’re used to.Using an eSIM Vietnam can be particularly useful for travelers, providing flexibility and ease of use.

Your plan activates immediately upon connecting your eSIM to any supported network. For example, if you bought a 1-day plan and you activate your plan at 10 AM, it remains active for a full 24 hours, concluding at 10 AM the following day.

The Vietnam eSIM only comes with cellular data. It does not include a local phone number for phone calls or text messages. You can still make calls using apps like WhatsApp.

You can check if your smartphone is one of the eSIM compatible devices here.

Once you purchase your eSIM, you will receive a confirmation email with instructions to install it immediately using a QR code or manual code. Remember that once the eSIM is purchased, it cannot be returned.

You don’t need to do anything to keep your WhatsApp number. You’ll automatically keep your number, contacts and conversations.

This eSIM data plan includes unlimited data for the corresponding valid days. However, please note that the operator may reserve the right to apply a Fair Data Usage Policy, as it applies to all other network users. In particular, if the operator estimates the usage of more than 90GB of data in a month, they may temporarily reduce the speed to between 256-1024KB to avoid affecting other users. This limitation is intended to prevent network saturation and will be removed within 24 hours. If you think the local carrier has limited your speed, please get in touch with us by chat, and we will check if there is any incidence and how to restore your rate to the maximum speed permitted by the network.
