## What is SIMTAG?

"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.
