Funcionou bem no Japão

Fiz uma viagem de 10 dias pelo Japão, passando por Tóquio, Osaka, Kyoto e Hiroshima. O eSIM funcionou em todos os lugares, inclusive no metrô de Tóqui...

Frequently Asked Questions (FAQ)

Find answers to the most common questions about eSIM

eSIM is a digital SIM card built into your device. It allows you to activate a data plan without using a physical SIM card. Simply install the eSIM in our mobile app or scan the QR code to install and activate eSIM.

Most modern smartphones support eSIM, including iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer. Check our compatibility page to make sure your device is supported.

After purchase, you'll receive an email with a QR code and detailed instructions. If you download our mobile app, you can install the eSIM automatically directly in the app — no need to scan any code. If you purchased via the website, simply scan the QR code with your phone camera and follow the on-screen instructions. The whole process takes only a few minutes.

Yes! eSIM is for data only. Your original SIM card stays in your phone, so you keep your phone number. You can receive SMS and calls on your regular number.

eSIM starts working immediately after activation when you're in the destination country. You can install eSIM before departure, but data will only start counting after you turn on data roaming at your destination.
