Before you depart, please make sure you have:

Step 1. Checked your device's eSIM compatibility

Note: To check if your device supports eSIM, please dial #06#. If a 32-digit EID number appears on your screen, your device supports eSIM.Step 2.* Checked your device is unlocked

Step 3. Registered your Arrival Date via our website here.

You can register your travel dates later for your eSIM. To ensure a seamless activation experience, we recommend registering at least three business days before your trip.

Once the eSIM QR code is generated, it is valid for 30 days. If you are traveling within 30 days, no changes need to be made to your activation date. If you are traveling outside of 30 days, please email us at hello@globalstarlink.com.au for further assistance.

Depending on the Marketplace you purchased from, there will be a different order number type. You can generally find this via the Confirmation Email, or by signing into your eBay or Amazon account and clicking into your order.

Unfortunately as the Vietnam eSIM is a data-only eSIM, it doesn't come with a traditional phone number for voice calls or SMS. Instead, it provides high-speed data connectivity for browsing the web, using apps, and staying connected online while you're in Vietnam.

We usually recommend using your device settings to check your data balance for the Vietnam eSIM. Unfortunately, aside from this method, there are no other ways to check your data balance. Depending on your device type, please use the following steps:

iOS*

Settings > Mobile > under Mobile Data for your [Vietnam eSIM name] > Current Period

The Vietnam eSIM is designed as a single-use eSIM and cannot be recharged or extended once it has been activated. If you need to extend your data connectivity beyond the initial duration, you will need to purchase a new eSIM for the desired duration.

The Vietnam eSIM Card is specifically designed for use in Vietnam. It provides high-speed data connectivity within Vietnam, allowing travelers to stay connected while visiting the country.

If you plan to travel to other countries, you may need to purchase a separate eSIM card or make alternative arrangements for connectivity in those destinations.

Since the Vietnam eSIM is a data-only eSIM, your family and friends won't be able to call or text you using a traditional phone number. Instead, they can communicate with you through internet-based messaging apps, such as WhatsApp, Facebook Messenger, or email. You can share your contact details or preferred messaging app username with them to stay in touch during your time in Vietnam.

If you are travelling for longer than the duration covered by the Vietnam eSIM, you will need to purchase another eSIM for the additional days you need. This allows you to continue enjoying high-speed data connectivity during your extended stay in Vietnam.

If you're having trouble scanning the code to activate your eSIM, don't worry! You can also do it manually using the SM-DP+ Address and Activation Code we included in your confirmation email. If you've tried the manual method and still need some assistance, our helpful team is just a message away! Feel free to reach out to us at hello@globalstarlink.com.au. We're happy to get you connected!
