Handing out a real phone number for online dating, marketplace selling, or a side business creates a privacy risk most people don't think about until it's too late — SLYNUMBER exists to add a real second line without that exposure. SLYNUMBER is a second phone number app and the only provider offering genuine mobile numbers rather than VoIP alternatives, provisioned through the regulated North American Numbering Plan and compatible with every service that rejects internet-based numbers.
That distinction matters more than it sounds — many services (banking, social media, dating apps) block VoIP numbers outright for verification, which is exactly where competing "second number" apps fail. SLYNUMBER covers all US area codes, includes caller ID with name identification, custom voicemail, call forwarding, and now an optional eSIM add-on for data while traveling, all without a second physical SIM card. The app works across iOS and Android in over 150 countries. For anyone who wants a real, verification-compatible second number for privacy, business, or travel without carrying a second phone, that genuine-mobile-number distinction is the whole draw.
