Number 1

This allows me to avoid having my personal number distributed. It comes in handy for so many things.

Not very secure

I don’t know why the cell phone prompts me to use either mobile call or Onoff when accessing my contacts list. I did not share my list with Onoff(they have respected that choice), but some how my cell still ask if I would like to use Onoff to call out from their end, and it will then, push the call through to the app.: this is not very secure because anyone using my phone can access the Onoff app using my contacts list by placing a call through the cell phone contact list.
I can also leave my house from my back bathroom window: it works, but it is not practical. Nor is the advice you gave my regarding the issues at hand. Have a good day.

Hello, like many communication apps, Onoff lets you use its features directly from your phone's native interface.

You can disconnect or deactivate your Onoff number at any time to avoid any unpleasant surprises.

Have a good day,

I wish it possible i won’t even give your app any star.

I want my money back, you should please take your number back, because I don’t get people text, it just a big waste for me. This is a big mess, my text are delivering to my friend but I can’t get their text. That a big rubbish and wasting of money... anyone who is about to use this app, just don’t waste your money, if your friends don’t have the app, and text you from the app, no way they can get your messages unless they call you that all. For anyone who is in the United state and buying purchasing +1 number. I so hate why I just wasted money for 3 month. If possible please refund my money back, I don’t need your number anymore, as I can’t get people text only their call and my text is going through.
