Holafly eSIM User Reviews

Frequently Asked Questions about the Vietnam eSIM

We’ve put together this list to give you the answers you need.

When does my data plan begin?


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.

Can I make phone calls and send messages with my Holafly eSIM?


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.

Which devices work with the eSIM card?


You can check if your smartphone is eSIM compatible here.

When will I receive my eSIM?


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.

Can I keep my WhatsApp number?


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

How quick is the Holafly eSIM?


The Holafly eSIM offers maximum speed coverage (4GLTE). But bear in mind that in some areas of limited coverage there may be a lower speed connection.

Do I have to activate data roaming on my device?


Yes. To ensure that your virtual SIM gets the best coverage, you must turn on data roaming on your phone’s settings. This will not incur any additional charges, as long as you have already the Holafly eSIM set up correctly.

What do I do if I delete or lose my eSIM’s QR code?


If you cannot find the code, please contact our 24/7 customer support team at [email protected] or our online chat function. We will resend the code to your email.

What happens if I use up my data or my days of validity?


If you use all your data or run out of days, your eSIM card will no longer work and you will lose internet connection.

What eSIM data plan should I choose for Vietnam?


Whichever is available for your destinations and suits your travel needs better! You can choose plans from 1 to 90 days.

Could the internet speed with my Holafly eSIM be reduced?


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 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.

What is an eSIM?


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.

Can I renew or extend the data on my eSIM?


Yes, you can do so by logging into your customer panel on the Holafly Center. You will find the data plans you can purchase there. Once you’ve made your purchase, it will be activated immediately on the eSIM you have linked.

Can I share data with other devices?


Certainly! With the Vietnam eSIM, you have the capability to share up to 500MB of data per day across devices by creating a WiFi connection using your smartphone. Refer to your device instructions for guidance on setting up a WiFi connection via a mobile hotspot.

How do I set up the eSIM on my device?


After your purchase, we will send a QR code and manual instructions to your email. Either print the QR code or open it on your computer. On your cellphone, go to Settings > Mobile Data > Add Data Plan and scan the QR code. You can rename the data plan on your phone. Then, you’ll be able to switch between your Holafly data plan and the original plan from your provider. The Holafly data plan will only be operational once you arrive at your destination. Once you land, turn on data roaming on your cellphone’s settings and activate the Holafly data plan. Check your phone’s user manual for more details on adding a data plan. All eSIM products come with comprehensive set-up instructions.

When should I set up my eSIM?


Set up your eSIM before your departure. Once you reach your destination, just activate the data plan, and turn on data roaming. We recommend you print the QR code and take it with you on your vacation just in case. Remember that you need a prior internet connection to activate the eSIM. Set up is quick and you will be able to enjoy your data plan right away.

How can I check my data balance?


You can manage your eSIMs and access all purchased data plans by logging into your Holafly Center through the Holafly website.

How many times can I use my eSIM card?


If needed or when changing phones during your trip, you can transfer your eSIM. However, note that you can only transfer the eSIM to two devices—the original one and a new one. Once you’ve installed it on a different device than the original, you won’t be able to reinstall it on the original device and you must deliver the eSIM from the original device to install it in the second device.

Can I delete the Holafly eSIM once I’ve used my data?


Yes! But keep in mind that you don’t need to do so. As soon as your plan expires your eSIM will no longer work.

Can I use my SIM card and Holafly eSIM at the same time?


If you are using an Apple device, you can use your SIM card and your eSIM at the same time. Choose the SIM card for phone calls and SMS, and Holafly eSIM for data from your device. Please remember that if you leave your SIM card activated, your network provider may apply data roaming charges to receive or make phone calls as well as send SMS.

How do I get a refund?


The eSIM is a digital product. Holafly cannot check if you have used the data plan associated with the eSIM card. Therefore, once your digital SIM is delivered, we cannot offer a refund. Please see our eSIM Refund Policy for more information.

To which mobile network will I connect at my destination?


Your eSIM will connect to all the local phone networks that Holafly partners up with. You can review them in the Technical Specs tab.

Is Holafly my best option?


It is! Of course if you ask us which eSIM card is the best, we will naturally answer it’s ours! Why? Because of our unlimited data, the flexibility to select a custom number of days, and many more special features
