What’s New

Version 3.2.14

This update of the onoff App brings a "dark mode" for a new visual experience. You can toggle this feature in the App's setting, from the side menu.
Also, following a lot of requests, the App is now available in Spanish!
We fixed some bugs in the process and reworked few of the in-app screens so they would be easier to understand.
We hope you'll like this new release.

The app has been working fine for me for the last few months. Recently my credits disappeared from my account but the issue was resolved through their customer service. I’ve tried all the other 2nd number apps however so far OnOff is the best in my opinion.

When placing a call it actually generates a local number you need to call using your normal phone and SIM card, so not only do you have to pay Onoff but you also pay your phone provider for a call - it’s not VoIP and doesn’t use WiFi. If you’re abroad forget it as your phone provider will be charging you a lot for the local call.

Finally they seem to be purchasing (very obvious) fake reviews for this app - some very similar 5 star ratings from randomly generated usernames. Look, if you’re going to buy fake reviews at least try to make them seem legitimate.

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