PSB

PSB delivers instant, disposable phone numbers for verification, privacy, and temporary communication directly on your device.

This tool generates secondary mobile numbers that function exclusively for receiving SMS messages. No SIM card, no carrier activation, and no personal data submission required. Each number operates as a standalone receiver for one-time passwords (OTPs), registration codes, and short notification texts. The application maintains a pool of real, active phone numbers from multiple countries, allowing users to bypass linking their primary line to untrusted services.

Core functionality and operational modes

• One-time number generation: Tap to request a fresh number from the available pool. The system assigns a working line within seconds. Numbers remain active for a predefined session window, typically 10 to 60 minutes depending on demand.
• Multi-country number selection: Choose from a list of supported country codes including the United States, United Kingdom, Canada, Australia, and several European nations. Each country pool contains dozens of concurrently active numbers.
• Real-time SMS inbox: Incoming messages appear in a chronological log. Each entry shows the sender number, message body, and timestamp. The interface supports copy-to-clipboard for OTPs and activation links.
• Number reuse and extension: Previously used numbers remain accessible for up to 24 hours after first assignment. Users can extend the active period for a specific number if a verification process requires multiple steps.
• History log: A searchable record of all numbers used, with associated messages and expiry status. Filter by date, country, or active/inactive state.

Key operational advantages

• Zero hardware dependency: No second SIM tray, no dual-SIM phone required. The software layer handles all number routing through internet connectivity (Wi-Fi or mobile data).
• No registration or account creation: Launch the app and immediately start receiving SMS. No email, no password, no profile setup.
• Session-based privacy: Each number exists temporarily. After the session expires, the number returns to the pool and becomes unavailable. No permanent link between the user and the number remains.
• Automatic message detection: The app polls the server backend every 5 seconds when in the foreground. Background refresh occurs at configurable intervals (every 30 seconds to 5 minutes) to conserve battery.
• Manual refresh control: Pull-to-refresh gesture forces an immediate check for new inbound messages.
