"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.
