This site is a scam. Once you sign up It is impossible to cancel. I had to cancel my credit card and get a new number for them to stop charging me!

I use SLYNUMBER for my business. It was easy to set up, great price, and very reliable. The app is also very easy to use, I like the design. Would highly recommend!

Great for my business. I am a dog groomer and needed a second number. This works perfectly! I have told all my friends about it.

I’m beyond impressed with SLYNUMBER! I originally called for a refund since I didn’t see a service that would fit my needs, but Dee responded almost immediately and reassured me that she’d help. Between Dee, the tech support team, and the engineer, they didn’t give up on finding a solution. It's so hard to find good support these days, especially from a company that’s willing to go the extra mile for a small business. The level of customer care I received was exceptional. Thank you, SLYNUMBER for your dedication and outstanding service!

It took a few days and much customer support to get my number up and running. However, happily, they were there to help and I am delighted that I can finally manage all my banking and other USA based needs while abroad. It's life changing - after living outside of the USA for 30 years - to finally have a USA number!
