Customer Reviews
super easy second number!
i needed a second number for my side hustle and slynumber's monthly mobile plan was perfect! used a promo code at checkout on their site, got a sweet discount on my first month. it's so much better than dealing with sideline or burner. definitely telling my friends, i'll be back for sure!
Easy to set up
Needed a second number fast. Got the Monthly Mobile Plan. Setup was simple. App works. Good service.
Mostly good, some app quirks
I signed up for the Annual Subscription Plan because the savings were too good to pass up for a Private Business Line. Setting up my Specific Area Code Number was quick and easy, which was a huge plus. Calls and texts generally work well. My only minor issue is the mobile app sometimes takes a second or two to load up completely, not a big deal but noticeable. The Professional Voicemail Service is a neat feature, though. Overall, a solid service for the price, just a tiny bit of lag occasionally on the app itself.
Amazing second number!
I absolutely love slynumber! I got the Yearly Subscription Plan for a Private Business Line and it's been fantastic. The call quality is super clear, and the SMS and Texting Service works perfectly for all my business communications. It was so simple to get my specific area code. I tell everyone about it, especially my friends who need a separate work line. I'm definitely renewing next year!
Good value for a second line
I was looking for a cheap way to get a second phone number for my side gig without buying a whole new phone or plan. The 3-Month Subscription Plan from slynumber was a pretty good deal compared to others I saw. It gave me enough time to try it out and see if it worked for my needs. The overall cost felt fair for what I got, and it definitely saved me some money in the long run. I'm happy with the purchase.
Got a privacy line
So I was kinda tired of giving out my main number everywhere, you know? Decided to try slynumber for a burner number service. It was surprisingly easy to get set up with a US Virtual Phone Number. I picked an area code that made sense for me, and it just worked. Used it for some online sign-ups and it kept my real number private. The app was pretty straightforward to use, no weird tech stuff to figure out. Felt good to have that extra bit of privacy.

Thinking about getting a second number for my side hustle. Anyone know if Slynumber lets you pick a specific area code? Need one for my local city.
Hey, anyone used Slynumber for a while? Wondering if they ever do any good deals, like for Black Friday or something. Don't want to buy now if there's a big sale coming.
