80Frequently Asked Questions
How quickly can an eSIM be activated?
After purchase, install it via a QR code or app. Enable data roaming after landing to start using it. Most plans support installing in advance, then activate automatically on arrival.
What is an eSIM?
An eSIM is an embedded SIM that needs no physical card. Just scan the QR code provided by the provider to install it on your phone, supporting multiple numbers on one device.
How do I install an eSIM?
After purchase you'll receive a QR code. Go to Settings > Cellular > Add eSIM, scan the QR code and follow the prompts. We recommend installing before departure and activating after landing.
Do eSIMs expire?
Plan validity starts from the activation date. After purchase there's usually a 30-day to 1-year installation window — check each provider's terms for details.
Can I use multiple eSIMs at once?
Most phones can store multiple eSIMs, but only one can be active at a time. You can switch between them for different trips.
