About

FlyoSIM

Read full description

FlyoSIM helps travelers buy and manage prepaid data-only eSIM connectivity for supported destinations. Browse current country, regional, and global offers and compare data, validity, coverage, network, and price before you travel. Choose a plan, review the server-confirmed all-in price, and complete payment on Stripe's secure hosted checkout in your browser. FlyoSIM verifies payment on its servers before provisioning and keeps the latest order status available in the app. Create or access your account with email, Google, or Apple. Signed-in customers can manage purchased eSIMs, view protected installation guidance, contact support, review legal information, and initiate account deletion from the app. Availability, coverage, speed, activation, compatibility, refunds, and terms depend on the selected offer, device, destination, and partner network. A compatible unlocked eSIM device is required. FlyoSIM plans are data-only unless an offer explicitly states otherwise and do not provide emergency calling.
