eSIMTools vs SIMTAG

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.

"Will that eSIM actually connect?" SIMTAG is an offline-first ledger for your eSIMs. Keep QR codes, APN settings, and notes in one place — everything stays on your device and opens even in airplane mode. WHEN IT HELPS - Before departure: your eSIM QR codes and APN details are scattered across emails - After landing: no signal, and you are not sure which setting to check first - Back home: you want a record of which eSIM worked where WHAT IT DOES Ledger - Add an eSIM four ways: scan a QR code, import from a photo, paste the activation string, or type it in - The original QR image, APN, expiry date, and notes are stored on your device and viewable offline anytime Install assistance - Guides you through APN settings first, then the eSIM installation itself - Illustrated step-by-step guides work without any connection When nothing connects - Answer a few questions and narrow down which setting to check next - Results state only facts: "detected" or "not detected" PRIVACY Your eSIM data (QR codes, activation codes, APN, notes) is stored only on your device and is never sent to our servers. Note: Whether a line connects depends on the carrier, device, and region. SIMTAG helps you organize and check settings; it does not guarantee connectivity. iOS does not allow apps to measure per-line data usage.
