The most compete option

When I set out to choose an internet based business phone system I did my research, narrowed it down to 4 options and signed up for service. Two failed instantly, the other was not far behind but Ninja Number has proven to be an asset to my over business workflow. The app is consistently upgraded with features that provide me with targeted analytics to assist me in connecting with my customer more frequently and on their terms. The billing process is seamless, support is knowledgeable and so far I have not had any issues at all. At first I did not like the BOT setup system but it did exactly what it was designed to do in setting up my system in minutes.

Simply put, this simplified my life

This app is great! It drastically cut the cost of me having a separate phone for my business and it’s so easy to set up and use. It’s like having two phones in one, and it does a great job of keeping my business calls and my personal calls in different places so I don’t have to spend time figuring out who to call back if I miss a call. I’ll definitely be recommending this to everyone I know who has their own business!

AWFUL stay away

No customer service, no support or technical help. If you're lucky enough to get through to the customer service, they're rude. I had an issue setting up the app becuase of a mistake on their end. They had my company name misspelled on their system so I could not use the app for several days while I was paying and giving my number for customers to call.

My number is hacked and I receive 2-3 calls EVERY DAY from hackers, spammers! Every day!I also receive calls from random people who call my number back because they’re scammed and then I try to explain and apologize to them that my number is hacked and it’s not me who is calling them but some scammer using the ninjanumber.

I asked about the hacked and hijacked number issue, no solution was offered from the customer service. They said it was just the part of the deal.
