eSIMTools is an eSIM-to-SIM toolkit for working with supported programmable eUICC and SIM modules. It helps developers, testers, integrators, and connectivity teams read card information, inspect installed profiles, and manage the path from an eSIM activation code to a writable SIM-style module. Use eSIMTools to read EID and eUICC details, view installed profiles, scan or manually enter eSIM activation codes, download carrier profiles, and write compatible profiles to supported eUICC cards. The app is designed for controlled eSIM provisioning workflows where visibility, repeatability, and clear reader status matter. Key capabilities: - Read eUICC card information and EID - View installed profiles and profile status - Scan QR activation codes or enter activation codes manually - Download carrier profiles through the LPA workflow - Write profiles to supported eUICC/SIM modules - Connect through compatible USB CCID readers - Connect to supported Bluetooth eSIM modules - Review storage and profile diagnostics before installation - Manage installed profiles from a clear profile console eSIMTools focuses on practical eSIM-to-SIM testing and provisioning. It is not a carrier service and does not provide mobile plans. Profile download and installation require a valid activation code, network access, and compatible reader or module hardware.
