NOT TO BRAG, WE ARE THE BEST SLYNUMBER is not just another second number app. SLYNUMBER is the ONLY provider on the market to offer real mobile numbers. We don't provide VoIP, fake phone numbers, or second lines that only work for a week. This distinction is crucial because many apps and online services do not accept VoIP numbers. SLYNUMBER works everywhere! To put is simply - unless you're willing to sign up with a major carrier like T-Mobile, Verizon, or AT&T and commit to an expensive plan with a SIM card and monthly bills, we are your ONLY alternative for obtaining an actual mobile number. Moreover, we prioritize your privacy and anonymity, allowing you to share your number with strangers, clients, acquaintances, blind dates, or anyone else without the fear of being tracked or spied on. HOW SLYNUMBER WORKS Setting up SLYNUMBER is fast and easy! Simply, download the app onto your phone, pick your number and start calling and texting.

We offer the most reliable and fully featured virtual phone number app available, with calling & texting features that include free toll-free calls, blocking, muting, and do-not-disturb mode, caller name & ID settings, SlyAI (running on ChatGPT-4), call forwarding, and number porting. And now we also offer an eSIM feature that will allow you to activate cellular data anywhere in the world. We are you one-stop shop for all things mobile. Use it for: -Privacy & keeping your information safe -Separating personal and transactional numbers -Your business needs -Job applications -Traveling abroad -Communicating freely with spam blocking & muting -Setting boundaries with do-not-disturb settings -Online or in-person dating Your private phone number can be risky if it falls into the wrong hands.

Grapevine is anti-social media: a private feed and chat for you and up to twelve friends. No strangers, no influencers, no infinite scroll designed to eat your evening — just your people, on one vine. THE FEED, WRITTEN FOR YOUR GROUP The Grapevine, your group's AI news desk, turns what's actually happening in your circle into posts funny enough to read. React with a heart or a laugh, plan movie nights and trips with real RSVP cards, run polls, and drop surprises. Your feed is about your friends — because it's written from them. PRIVATE BY DESIGN • Direct messages and 1:1 calls are end-to-end encrypted. • Reactions are anonymous — nobody, including us, sees who reacted. • We don't sell your data, run ads, or retarget you. Cosmetic looks are 100% of how we make money. CHAT LIKE A TRIBE One group chat for the whole vine. Any message can sprout a "vine" — a side-thread only its members can see. Stories that vanish in 24 hours. Voice notes, memes with a built-in meme maker, and an AI you can summon with @grapevine. MAKE IT YOURS Dress your messages in limited-edition chat bubbles and themes — from comic-book balloons to the gold Suleymane Crown. Editions have a public, fixed supply, and you can gift them to friends. Buy them with grapes, the in-app currency. INVITE-ONLY, ON PURPOSE You get in with a friend's code, and your grapevine holds twelve people. Small is the point. Grapevine is for ages 13 and up.
