About this app
Tired of anxiety before pressing call?
Are you a Single SIM user who needs to hide their number for clients or patients, but hates digging through settings every time? Are you a Dual SIM user sick of the constant "Which SIM?" pop-up, or terrified of accidentally calling your boss from your private number?
PaSS (Prefixer and SIM Selector) handles all of this effortlessly. Stop thinking, just dial. Set your rules once, and the app automates the rest right before the call connects.
Enjoy PaSS completely free for the first 30 days. Afterwards, a single one-time in-app purchase unlocks unlimited use forever.
TWO POWERFUL SOLUTIONS IN ONE APP
📱 FOR EVERYONE (SINGLE & DUAL SIM): Smart Prefixes & Privacy Take control of your outgoing number without changing system settings.
✅ Instant Anonymity: Automatically add prefix codes (like #31#, *67, etc.) to hide your Caller ID only for specific contact groups (e.g., "Patients").
✅ International Dialing: Automatically add country codes or replace "+" with "00" based on number patterns.
✅ Number Cleanup: Remove trigger characters or enter pauses automatically.
📲 FOR DUAL SIM USERS: Intelligent Selection Separate work and personal life automatically.
✅ Work/Life Split: Link your Exchange contacts account to SIM 1 (Work) and your Google contacts to SIM 2 (Personal). Never choose the wrong SIM again.
✅ Smart Defaults: Set rules for unknown numbers or define a default SIM for specific area codes.
⚡ THE "SUPER-USER" COMBO: Time & Context Rules Combine conditions for ultimate control.
✅ Office Hours: Route calls through your work SIM during weekdays between 9-5, but switch to private or ask on weekends.
✅ Visual Confirmation: Optional colored notification bars show you exactly which rule is active before the phone starts ringing.
How it Works (Simple IF → THEN Logic) You build rules efficiently in minutes:
IF [a certain condition is met] (e.g., It's a weekday AND the contact is in the 'Clients' group)
THEN [perform actions] (e.g., Hide Caller ID AND use Work SIM)
