- Travel eSIM
-
What is an eSIM?An eSIM is a built-in SIM card found in eSIM-capable devices that makes staying connected easier and more convenient. With an eSIM, you can download data packs directly to your phone, so you don't have to worry about finding or losing a physical SIM card.
Important: eSIMs only work on devices that are both eSIM-compatible and network unlocked.
To check if your device is compatible with eSIMs, you can either look at our list of eSIM-compatible devices or check your device’s settings.
If your device supports eSIMs, simply get a Travel eSIM to unlock its full potential. Once your eSIM is installed, you can easily top it up whenever you're running low on data. -
What is a Travel eSIM?A Travel eSIM is a data-only pack that gives you a set amount of data to use within a specific time frame. It’s designed for easy use on your eSIM compatible device. Please note that, for the moment, Travel eSIMs don't come with a phone number and don't support voice calls or SMS.
The best part? If you’re running low on data, you can easily top up your Travel eSIM to stay connected. -
When can I install my eSIM?To determine the appropriate timing for eSIM installation, it is essential to have knowledge of the activation policy.
For most eSIMs, activation occurs only at the destination when they establish a connection with a supported network or any of the supported networks. However, there are also eSIMs that activate immediately upon installation, regardless of the location.
How can I determine the activation timing of my eSIM? You need to review the activation policy specific to your eSIM.

2. Choose your preferred eSIM.
3. Verify the Additional Information provided.
4. Click on "More details" to locate the Activation Policy.
The activation policy can be described as follows:
1. "The validity period starts when the eSIM connects to any supported network(s)": This means that you can install the eSIM before your travel without activating it. Upon reaching your destination, you can activate the eSIM by turning on your eSIM line, as long as you have completed the setup as advised on your eSIM installation page.
2. "The validity period starts at the installation": This implies that your eSIM will activate instantly upon installation, and therefore, the validity period will commence even if you have not yet arrived at your destination. -

-
How do I know if my phone is compatible?You will have to check if your device is eSIM compatible and unlocked for network usage. Device compatibility may vary depending on the carrier and country of origin, so you should refer to the list of eSIM compatible devices provided here.
-
Can I use tethering (Personal Hotspot)?Sure, you have the option to use your personal hotspot in conjunction with your eSIM, if both your device and the network support this feature.
-
Can I reinstall an eSIM?Travel eSIMs generally can’t be reinstalled once removed. To avoid any issues, we recommend keeping any eSIMs you still plan to use.
If you remove an eSIM from your device, you might have trouble downloading it again. In that case, you would need to buy and activate a new eSIM to connect to mobile networks at your destination.
Instead of removing your Travel eSIM, consider temporarily disabling it when not in use. Just remember, the validity period continues to run even if your eSIM is disabled.
If you’re running low on data, you can easily top up your existing eSIM to stay connected, so there’s no need to remove it. -
Why have I received the “This code is no longer valid” error message?This error message occurs when attempting to add an eSIM that has been added previously, or when the QR code was only partially scanned due to a weak connection.
Please be aware that if the eSIM has been removed and you try to reinstall it, it will not work.
If you are installing the eSIM for the first time, this error message may arise due to a weak connection, enabled VPN, or an excessive number of eSIMs installed on the device. -
What do I do if my device is network locked?eSIM installation is restricted to devices that are both compatible with eSIMs and have been network unlocked. Please reach out to your mobile carrier to unlock your device.
Furthermore, if your device has recently been unlocked, your carrier might have temporarily disabled eSIM support as a security measure. Please get in touch with your mobile carrier to unlock your device or bypass the security settings. -
I’m receiving the ‘Cellular Plans From This Carrier Cannot be Added’ error message. What now?This error may be displayed if you attempt to install an eSIM on a device that is locked to a specific network.
To determine if your device is locked, please follow these instructions:
1. Go to Settings > General > About.
2. Look for the option labeled "Carrier Lock".
3. If you see the message "No SIM restrictions", your device is not locked. If you do not see this message, please reach out to your carrier to request unlocking your device.
If your device has recently been unlocked, your carrier might have temporarily disabled eSIM support as a security measure.
Please get in touch with your mobile carrier to unlock your device or bypass the security settings. -
I’m receiving the ‘Unable to Complete Cellular Plan Change’ error message. What now?The "Unable to Complete Cellular Plan Change" error message is related to an installation failure which can be caused by different factors:
1. Too many eSIMs are installed on the device. eSIM compatible devices allow you to install multiple eSIMs, but depending on the device model, the number of eSIMs you can have active simultaneously may vary.
2. Cellular/Mobile data is disabled in the device’s settings
3. Trying to install an eSIM that was already installed: most eSIMs can only be installed once.
4. Poor connection when trying to install the eSIM. This commonly happens when using the ship’s Wi-Fi or public Wi-Fi. -

For existing Travel eSIMs, simply check the top-up option in My Account. If no top-up options are available, it means the eSIM isn’t rechargeable, or there may have been a change with the network carrier. In that case, you’ll need to purchase a new eSIM.
-
Can I reuse the same Travel eSIM?Yes, if you plan to use the same Travel eSIM again, there's no need to delete it — just keep it installed and turn it OFF under Cellular Data Plans when you're not using it.

What is 3D-Secure?3-D Secure is a global e-commerce solution that enables cardholders to authenticate themselves to their card issuer through the use of a unique personal code/password. When you make a purchase, you may be redirected briefly to your bank/issuer website to enter your 3D-Secure password and when your bank/issuer accepts this, then you are redirected back to our website to complete the purchase. This solution addresses current consumer concerns about the security of online shopping and the high rate of e-commerce fraud and it is designed to take online shopping security and consumer confidence to a new level.
For VISA customers the security check will appear under the name "Verified by VISA". For MASTERCARD customers the security check will appear under the name "MasterCard SecureCode". -
Why have I been asked to enter a password when making a purchase?This is a 3D-Secure security check directly from your bank/card issuer. When you make a purchase, you may be redirected briefly to your bank/issuer website to enter your 3D-Secure password and when your bank/issuer accepts this, then you are redirected back to our website to complete the purchase. If the bank/issuer is asking you to enroll for 3D secure or enter a password for 3D-Secure and you want to skip this, then you must get in touch with the bank directly.

Please get in touch with your mobile carrier to unlock your device or bypass the security settings. -
I’m receiving the ‘Unable to Complete Cellular Plan Change’ error message. What now?The "Unable to Complete Cellular Plan Change" error message is related to an installation failure which can be caused by different factors:
