Forget memorizing numbers! Dial your contacts by name, not number. Borrow any device or landline to connect instantly in less than a minute! LOST101 is an offline contact backup network that turns any borrowed device or landline into your personal speed-dial. No passwords to remember, no long digits to memorize, and completely independent of your own device’s battery, screen, or cellular service! SIMPLE 3-STEP CONFIGURATION 1. Build Your Relay: Add up to 20 trusted emergency contacts straight from your address book. 2. Secure Consent: Your contacts receive a private text invitation to securely link their lines. 3. Lock It Down: Choose a unique voice signature, a secure keypad PIN, or both to protect your network. If you ever find yourself without your phone, dial 1-888-LOST-101 from any phone, verify your identity, then say who you want to call. PRIVACY-FIRST ARCHITECTURE - Number Masking: Callers and recipients never see each other's actual numbers during a relay. Both sides see LOST101 to keep personal data completely private. - Consent-First: To prevent data hoarding and respect personal boundaries, your contacts must explicitly agree to opt-in before they can be reached through your network. - No Marketing Spam: Your contacts and data are encrypted. We do not sell your information. SECURE IDENTITY VERIFICATION Prevent unauthorized access to your inner circle. Your custom security key ensures that only your words or PIN can unlock and trigger your contact relay from an external device. READY TO START? Your account includes 1 free test call that expires 7 days after signup—no credit card required to build your relay. Configure your line today so you can navigate the world with total peace of mind tomorrow. LOST101 is designed for personal contact relay use. It is not a replacement for 911 or official emergency services.
