eSIMTools vs JZ eSIM

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.

JZ eSIM is designed for Jiuzhou CPE/eSIM devices. The app helps users connect to a supported Jiuzhou CPE device over Wi-Fi, check the current eSIM status, activate an eSIM profile, manage available profiles, and perform local device firmware upgrades when supported by the device. Key features: - Detect supported Jiuzhou CPE devices on the local Wi-Fi network - Check eSIM activation and profile status - Scan or enter an eSIM activation code - Activate, switch, or delete eSIM profiles - View device and mobile network status - Upload a local firmware package and start device upgrade JZ eSIM works with supported Jiuzhou CPE/eSIM hardware. Some features require the phone to be connected to the device Wi-Fi network and may require camera, local network, and location permissions for QR scanning, device discovery, and Wi-Fi detection.
