SLYNUMBER can do everything your primary mobile number can but with added privacy and more features. 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.

Great Application but need to improve some bugs. After giving permission to contacts the app is not fetching contacts this error is in iOS devices not in android phones. Try to rectify this error and app need to improve for faster loading.

Developer Response
Thank you so much for sharing this feedback. We really appreciate it.Regarding the contacts permission:1. Go to Settings → SLYNUMBER → Contacts2. Toggle Off → On3. Fully relaunch the appThis usually refreshes the permission sync.

Such a waste of time and money and can’t rely on it

I had a very disappointing experience with SLYNUMBER.I downloaded the app, made the payment, and followed the steps exactly as the app showed. Everything seemed fine at first. Then the very next day, the UI/UX changed, I was suddenly logged out, and after that I could not log back in.The biggest issue is this: I tried logging in again with the same email, but it showed that the account was not linked. I had originally used Sign in with Apple through their newer design, but after the app changed, that option was either not working properly or not prompting the same way. So I was stuck outside my own paid account.What made this much worse was customer support.I contacted them and shared everything clearly, including my subscription details, screenshots, and screen recordings. Over the course of two days, I explained the issue 10 to 15 times in different ways so there would be no confusion. Instead of actually solving the problem, they kept sending repetitive replies like:•log out and try again•use stable Wi-Fi•explain the problem in more detailThis was after I had already given them more than enough detail. It felt like they were not trying to fix the issue, only delaying the conversation with copy-paste responses. Their replies were slow, and every message pushed the responsibility back onto me, as if the problem was my mistake, even though the issue started right after their app update and design change.When a user has paid, loses access after an update, and provides proof, the support team should take ownership and resolve it quickly. Instead, I felt ignored, blamed, and trapped in an endless support loop.Based on my experience, this app is not reliable. If something goes wrong with your login or account access, do not expect fast or effective help. I cannot trust a service where I can pay, lose access after their changes, and then spend days chasing support without a real solution.Would not recommend.
