Frequently Asked Questions

It’s super easy! After receiving your eSIM details by email, go to Settings > Cellular/Mobile > Add eSIM/Cellular Plan on your device. Enter or scan the eSIM information, enable data roaming, then restart your device. That's it! For more detailed instructions, check out the device-specific steps in your eSIM email.

Activating your eSIM is easy! After setting it up on your device, it usually activates instantly. If not, restart your device and voilà, you're active and connected!

Immediately! We'll send you your eSIM details via email soon after your purchase, usually within a few minutes. It’ll have all the details about your eSIM, how and when to install & activate!

You should install your eSIM on the day you fly. Once you install the eSIM, add in the Confirmation Code when the prompt shows, which is a 4-PIN number that you’ll receive in your email along with the eSIM.

This eSIM’s validity starts upon installation.

Absolutely! If your phone is dual SIM compatible, you can use your eSIM and a physical SIM at the same time. This means you can use one for data and one for calls.

Unfortunately, this is a data-only eSIM so it does not come with calls & texts. We’d recommend using data apps like Whatsapp, Messenger, Viber & Skype to make calls & texts using your data while travelling!

You can find how much data you've used in your phone settings!


Settings > Mobile > Scroll to find Current Period Roaming

If you're using a wifi device, unfortunately, there's no way to check your usage.


Settings > Connections > Data Usage > Billing Cycle and data warning > Select the period from the day you started using the SIM to the current day. Save and your data usage will be shown

We’d recommend grabbing a new eSIM from the website and following the same installation & activation process to get more data! We don’t offer top-ups at the moment!

eSIMs are designed to only be used on one device so once you install it - don’t uninstall it as it cannot be reinstalled again.

Unfortunately I did not get a chance to use the item because it was not able to work as promised. The customer service was great however as they attempted to assist me in every way possible. In the end the money was refunded because the product did not work.
