Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
FlyoSIM
Read full descriptionHide 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.
RoamUno
Read full descriptionHide full description
RoamUno helps you explore prepaid, data-only travel eSIM plans and manage your RoamUno account. Search destinations, compare current USD catalogue prices, and review data allowance, validity, activation and fair-use details. Keep plans in a local comparison list without signing in. Create or sign in to an independent RoamUno account with an available Apple, Google or email-code option, without buying first. Options depend on your platform and service configuration. Website orders connect only after you separately verify both accounts; matching emails do not connect them. An unconnected account has no website order history. Accessible history follows the verified account snapshot and may not include every older order or delivered plan. Historical records keep their original amounts, currencies and quantities. Missing original plan terms remain unavailable. The app protects RoamUno credentials in Keychain or Keystore. Access lasts up to five minutes and can renew within a seven-day idle and thirty-day absolute session limit. Sign out on this or all devices. Manage your display name, verified recovery contact and sign-in methods; request an account data export or deletion. Requests are pending review, not immediate completed export or erasure. Where a verified supplier report is available, view fixed-plan data usage. Reports may lag 2–3 hours; unavailable usage is never displayed as zero. Find compatibility and installation guidance and contact support. Purchasing and eSIM installation are not available in this version. eSIMs provide mobile data only, without a phone number, voice calls or SMS. Catalogue prices are in USD; historical orders retain their original currencies. RoamUno is operated by JUMPI GLOBAL LTD, registered in England and Wales.

Verdict
The clearest difference is iOS requirement: FlyoSIM at 14.0 against RoamUno's 16.4. On price, ads, in-app purchases and device support there is nothing between them.
