Powerful Features, Simple Control
🧠 Smart Dual SIM Management
Stop the "Which SIM?" pop-up. Assign contacts, contact groups (labels), or even unknown numbers to a specific SIM automatically.
⚙️ A Rule Engine for Everything
Combine conditions for ultimate control. Apply a rule only on workdays, between 9-to-5, or if the number starts with +44.
✏️ Number Rewriting
Automatically add prefixes (like #31#), replace country codes, or remove characters. PaSS dials it.
How it works
What is PaSS?
PaSS is a call redirector app. It sits silently in the background. When you dial a number, PaSS intercepts it, checks your rule list, and instantly applies the first rule that matches.
The 'First Match' Wins
This is the core of PaSS: the app reads your rules from top to bottom. The very first rule in the list that matches the number you are dialing, 'wins'.
The app then stops, performs the actions for that single rule (rewrites the number, chooses the SIM), and skips the rest of the list. This means your rules should be ordered from most specific to most general.
