Comments on SLYNUMBER for Android

★★★★★ Vit Vics · Oct 30, 2025

1 star. Does not work after latest update. I just signed up, purchased a full year and was happy that both WhatsApp and Telegram accepted the number for validation (they did NOT treat it as Virtual). However, shortly after, on 23/10, the pushed update broke the app and it no longer opens. Many other users report same. Upd 10/29 Latest Android Beta update fixed the issue without new Sly Number version. Maybe the problem was on Android side. Back to 5 stars as the app, service and price are great

This app makes claims that they do not give out VoIP numbers... which was very interesting to me upon reading... and had me curious about a few things... I rarely find an app that lets you pick a number for free... that doesn't require you to pay right away....that is a very top tier kinda service... if the call quality is good and if messages push through the notification system properly written without delay. I'm pleased to say this app has earned my 5-star rating, until further notice! Very good

Avoid this service. I paid $50 for an annual plan because SLUMBER advertises that their numbers are real, non-VoIP U.S. numbers that work with WhatsApp. The number they assigned me was immediately blocked by WhatsApp for security reasons. I contacted support, and they actually replied promising to give me a working replacement number. However, they never followed through. After that empty promise, they completely stopped responding to my emails and ghosted me. NOT Recommended at all!!

Absolutely terrible service — stay away. I used Sly Number for WhatsApp and OTP codes from my banks, with auto-renewal enabled on my account. When the renewal date came, their system failed to charge my card. Instead of notifying me, retrying the payment, or giving me any kind of grace period to update my billing details, they silently cancelled my plan and immediately resold my number to someone else. Let that sink in: a number tied to my WhatsApp account and my banking OTPs — now in a strange
