What is eSIM and which devices can use it?
An eSIM is an electronic SIM card built into the phone, eliminating the need for a physical SIM card. You can use it immediately by scanning a QR code. iPhones from the XS onwards, many Samsung Galaxy models, Google Pixel phones, etc., support eSIM. However, some iPhone and Samsung models purchased in Japan, China, Macau, and Hong Kong may not support eSIM.
How do I install an eSIM?

Is it possible to install multiple eSIMs on a single device?
You can install multiple eSIMs on one device. However, please note that only one eSIM and one physical SIM can be used simultaneously, allowing you to use two different phone numbers on the same device. You can change each eSIM's internet connection in the "Mobile Data" settings. It's advisable to give your eSIMs easily recognizable names, especially when installing multiple eSIMs on one phone.
Can eSIM be used in conjunction with a Vietnamese SIM card?
Absolutely. You can keep your primary SIM for domestic calls and messages while using Aviro's eSIM for internet access abroad. This feature is very convenient, doesn't require removing the SIM, and ensures continuous connectivity. Make sure your primary SIM is registered for roaming before leaving Vietnam. Do not enable the "allow mobile data switching" function to prevent your phone from using data from your primary SIM. Using roaming from a Vietnamese SIM can be very expensive and cause signal interference in some cases, so unless absolutely necessary, we recommend turning off your Vietnamese SIM line and using only your Aviro line for your phone.
Does eSIM support data tethering?
Most eSIMs allow data sharing via a hotspot. However, depending on your provider and phone model, some plans only support internet access for the device with the eSIM and do not allow Wi-Fi sharing to other devices. Therefore, you should carefully check the eSIM plan information and your phone's configuration before purchasing to ensure data sharing is available.
Can the Aviro travel eSIM be used in many countries?
Yes. Aviro offers many eSIM packages that work in multiple countries, allowing you to connect to the internet in many destinations with great convenience. For example, regional eSIM packages such as those covering 35 European countries, China - Hong Kong - Macau, Singapore - Indonesia - Malaysia - Thailand, etc., can work in many countries. You just need to check the list of supported countries in the package description to choose the one that suits your needs.
How long is a travel eSIM valid for?
Depending on the package, eSIMs can have a validity period of 1, 3, 5, 7, 10, 15, 20, or 30 days . This period is calculated from the moment you activate the eSIM, not from the time of purchase. Please note that the QR code is valid for 30 days; if there are any changes to your flight schedule, please contact Aviro for assistance in canceling and receiving a new package. With flexible options such as daily packages and data packages, you can easily choose an eSIM package with a validity period that suits your travel schedule.
Can devices other than mobile phones use eSIM My SIM?
This depends on your device's LTE band and the LTE band in the country you're visiting. The LTE band on this device (not this phone) must match the band in the country you're visiting.
LTE networks use multiple frequency bands:
- North America: primarily 700, 1700, 1900, and 2100 MHz
- Europe: mainly 800, 1800, 2600 MHz
- Asia: 1800, 2600 MHz
- Australia: 1800 MHz
- Taiwan: 700, 900, 1800 MHz
Therefore, the device may work well in one country but not in another if it doesn't support the appropriate frequency band. Thus, you need a multi-band supported device to use Aviro eSIM for international trips.
For devices other than mobile phones with a physical SIM slot, please contact our customer service department for advice on whether the device supports eSIM and network roaming.
