onoff is the most advanced communication application ever created and the only application that allows you to effectively manage all facets of your life!

Create and communicate via your multiple numbers (Business, Personal, Friends...) according to your desires. With onoff, you decide on your availability. While you're offline on your Pro number, you might want to stay in touch with your friends...?!

With onoff, you also instantly have several custom phone numbers from any country in the world on your smartphone without multiplying SIM cards.


- Generate multiple mobile phone numbers
- ONOFF WEB: Send and receive SMS and Calls directly from your web browser!
- Delayed SMS; schedule your SMS or eMessages to be sent at any date or time by holding the "send" button for a second
- "on"/"off", activate or deactivate your numbers at will
- Access your onoff numbers from any smartphone or device, anywhere.
- Customizable voicemail for each of your numbers
- etc...
Calls and messages are deducted from your regular carrier's monthly SIM plan (voice & data).


Within the app, you can subscribe to a number (from any country) or to a calling package. Prices vary per number country or package destination, and per subscription duration. Available subscription durations are 1, 3 and 12 months. The longer the period, the lower is the subscription price per month. Payment will be charged to our iTunes Account at confirmation of purchase. Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. iTunes Account will be charged for renewal within 24-hours prior to the end of the current period. Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase. Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription to that publication, where applicable
