Most current iPhones (XS and later) and many recent Android flagships support eSIM. The phone must be carrier-unlocked. Peak eSIM checks compatibility when you open the app and warns you if the device does not appear to support eSIM.
Plans typically start when the eSIM is installed and first used on a supported network, or according to the validity shown on the package. Check the plan details in the app for the exact start rule and duration.

If a plan cannot be used because of an error on our side, contact us within 30 days. Approved refunds go back through the App Store or Google Play and can take up to 30 business days to appear.
Write to support@peakesim.com within 30 days of the charge with your order details and a short explanation. We will investigate and follow up. Do not share full card numbers — Apple and Google handle card details, not Peak eSIM.

Increase screen brightness and avoid glare. Scan from another device if the code is on the same phone. Some Android phones allow adding an eSIM from a photo. If scanning still fails, contact support with your order details and we will help with a manual activation code when available.
Usually no. Locked devices often block other carriers, including eSIM data plans. Ask your home carrier to unlock the phone before you travel, then install Peak eSIM.
