Confirm that your phone is not carrier-locked before completing the purchase. The app checks the device you are currently using. If the compatibility banner does not appear, use the manual checks below or contact support before buying. Check your carrier-lock status - On iPhone, open Settings → General → About and look for Network Provider Lock: No SIM restrictions. - On Android, open Settings → Connections → Mobile Networks and look for an unlocked status. Menu names vary by manufacturer. A carrier-locked phone may reject a SimSIM profile even when the model supports eSIM. Contact your mobile provider if the device shows a lock or restriction. ⚠️ Warning: Check compatibility before purchasing and installing. If you are unsure, contact support before you scan or install the eSIM.
