## What is SLYNUMBER?

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.

### 5/5 — John

*2026-08-23, version 3.4.3*

An amazing and a user friendly app 👍

### 2/5 — Great but

*2026-08-11, version 3.4.3*

This was one of my favorite apps because i travel alot and use all its feature but several updates ago the app started bugging. 1) i use vpn for safety because im always connecting to public wifi and when the vpn is on calls dont work(i receive them but when i try to answer nothing happens) 2) i get calls from the US it and the caller id doesn’t show the number only the city where the caller from and even worse it doesnt log the missed call. Please fix these bugs im using my normal line now with roaming untill the issues are fixed

### 1/5 — Great app with bugs

*2026-08-10, version 3.4.3*

Great app but with some bugs and limitations …
For exemple the app doesn’t alert you about a missed call, you need to open all the time the app to check.
The app also show “yesterday” for any missed call or message received “today” but will show the right day for voicemail.
Besides the bugs, for call, text or data, all the Caribbean plus some country like Portugal where Slynumber won’t be available.
Let’s hope in the future they will improve this great app.

### 3/5 — Great app with bugs

*2026-08-08, version 3.4.3*

Great app but with some bugs that for sure will be fixed i guess in the future.
Also all the Caribbean plus some country where Slynumber won’t work either for phone call or data, let’s hope in the future it will improve

### 5/5 — Fantastic app

*2026-07-06, version 3.4.0*

I use this app all the time to talk to my patients. This way my privacy and identity are protected. It is such an easy app to use. Ii am not a tech savvy person. If I can handle it anyone can.

### 1/5 — Didn’t work with Venmo

*2026-07-01, version 3.4.0*

This company claims that it will work with Venmo but I can’t take payments without friends and clients getting a scam message.  No good.
