Frequently Asked Questions

An eSIM is an electronic SIM card built into your phone, eliminating the need for a physical SIM card and enabling it to be used by scanning a QR code. It's supported by iPhone XS and later models, several Samsung Galaxy models, and Google Pixel phones. However, some iPhone or Samsung models purchased in Japan, China, Macau, and Hong Kong may not be able to use eSIM.

• eSIM:
  After completing payment, you will receive a QR code via email. Please follow the instructions on the product page to install the eSIM using Wi-Fi or mobile data. Generally, the eSIM validity period begins upon activation, so it is recommended to install it on the day of departure to avoid wasting days of usage.
• Physical SIM:
  The SIM card will be delivered to you by the logistics company. Upon receipt, insert it into SIM card slot 1 (if your device has dual slots), set it as the mobile data source, and enable roaming. Some plans will automatically activate when you first turn on your device to access the internet. For additional settings, please refer to the instructions included with Aviro.

If the installation fails or you can't access the internet after scanning the QR code, please confirm that you are connected to Wi-Fi and follow the instructions. If the problem persists, you can contact Aviro via live chat. If you are overseas, we recommend finding Wi-Fi at the airport or hotel and then contacting them.
