About this app

**Your SIM, your contacts, your devices. Nothing leaves them.**

SIM Vault is the privacy-first successor to the classic SIM Manager. It keeps
your contact backups entirely on your phone and moves them straight to your
other devices — over your own Wi-Fi or Bluetooth — without the internet ever
being involved.

**◆ Vault — backups that stay yours**
Select any contacts and save them as named snapshots inside the app. Snapshots
never sync, never upload, and are even excluded from system cloud backups.

**◆ Transfer — phone to phone, encrypted, offline**
Send a snapshot to SIM Vault on another Android phone or an iPhone:
• Wi-Fi: both devices on the same network or one device's hotspot
• Bluetooth: Android to Android
Every transfer is end-to-end encrypted (ECDH + AES-256-GCM), and a 6-digit
code shown on both screens proves no one is in the middle — the same idea as
Bluetooth pairing codes.

**◆ SIM & network panel**
Carrier, country, slot, eSIM status, network type, roaming and your number —
for every SIM in a dual-SIM phone. Honest by design: Android 10+ blocks apps
from reading IMEI/ICCID/IMSI, so SIM Vault tells you that instead of showing
fake values.

**◆ Export & import**
vCard (.vcf) and spreadsheet (.csv) files through the system file picker —
compatible with Excel, Google Contacts and iPhone.

**◆ What SIM Vault does NOT do**
✗ No ads · ✗ No analytics · ✗ No account · ✗ No cloud · ✗ No internet access
to your data — the only network traffic is the direct, encrypted link between
your own two devices, on your own network.

Can't close some time. Ask money to export. Don't waste your time

it don't let you make back up unless you pay them, and there are adverts
