SLYNUMBER has a new look! We have updated everything from our logo, website and interface. What’s more exciting: new features have been added to improve communication, making it easy and efficient, such as international calling, full spam blocking, do-not-disturb mode, call forwarding, and more!
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.
SLYNUMBER can do everything your primary mobile number can but with added privacy and some really cool features. 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. Our main protective measure is ensuring that SLYNUMBER does not gather any personal information apart from what is required for processing payments, which remains inaccessible. Using SLYNUMBER, you can establish barriers through features like spam call blocking and do-not-disturb settings to guarantee that you always have control over your communications.
