Great to have a US number I can take wherever

My family and I are traveling to Europe for several months. We got slynumbers so people can call us on US numbers for personal and work wherever we are. For me, it was an added advantage that I can also use the number when I sign up for things like products (I just used it to sign up for ChatGPT) and my wife can put the phone number on her business's website so people can contact her and not have her actual cell number. Great price and works great!

Incredible app

I can’t say enough about how please I am with this app and how well it’s worked! I had a small problem arise where someone tried to use my number to scam someone and there customer service was incredible and helped me take care of it! In this day and age where many don’t put and emphasis on service, that is not the case with SLYNUMBER! I can say enough good things and grateful for there app and service

Bad experience with trial

I wasted nine dollars this week. What I experienced is the opposite of what their website claims. The first 24 hours was a no-show. Their app would not take incoming calls or text. I had to keep responding to tech-support with the facts, but they kept trying to get me to do Mickey Mouse steps like reboot my phone or restart the app. Finally, they understood the issue and they changed my phone number. So now that problem is solved but now I discover you can’t use this for signing up for social media or craigslist or Gmail or even Google voice. It knows this is not a real mobile number. the tech-support person ghosted me after I said I wanted a refund after explaining all this.
