Description
Need to add a prefix, suffix, or special code before calling?
With Call Prefix, you don’t need to edit your contacts anymore. The app automatically inserts codes like *67, *82, *70, 10-10-XXX, #31#, and more — instantly applied to your outgoing calls.
✨ Key Features
➕ Automatic prefixes and suffixes without touching your contacts
📲 Smart widgets: manage prefixes, suffixes, and caller ID directly from your home screen
🕵️ Anonymous calls: quickly enable/disable *67 or #31# to hide your number
☎️ Per-call options:
*67 → Hide Caller ID
*82 → Show Caller ID (unblock)
*70 → Disable Call Waiting
10-10-XXX → Carrier dial-around codes
⏸️ Skip operator voice messages (where supported) after a few seconds
🌍 International control: remove or replace “+” and “00” for easier international dialing
🆘 Emergency numbers automatically excluded for safety
🔐 Privacy & Security
❌ No access to your contacts
❌ No personal data collected
✅ All numbers are processed locally on your device
💎 Usage Modes
🎁 Free trial: 24 hours of full access after first install (no charge)
🎬 Rewarded ads: watch a short video to extend usage by 1 day (max 5/day, every 30 min)
💳 Premium: one-time payment ($4.99) for lifetime unlimited use (no subscription, no auto-renewal)
⚙️ Requirements
📱 Android 10 or higher (API 29+)

Disable call waiting with *70 during important calls
Use 10-10-XXX codes for alternative carriers
Manage everything directly from widgets
