By MR IU PING CHUNG, from Google Play“Back up contacts on your phone only. Move them device-to-device. No cloud. Ever.”
Description by MR IU PING CHUNG Written by the developer, not by AppBrain. Click to read.
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.
