What Onoff Numbers Is Used For

Onoff Numbers appears to be a communication app for getting and using a second phone number on an Android device. Based on the metadata, it is commonly used to separate personal and work calls, keep a main number private when posting online or contacting buyers, and handle calls and SMS from a number that can be managed inside the app. The app type and permissions also suggest it is designed for normal phone functions such as calling, messaging, contact syncing, and voicemail.

It may also be useful for people who want a number that can be used across devices, since the description mentions access from a smartphone and web browser. The metadata points to features like low-cost international calling, unlimited calls and SMS in some plans, visual voicemail, and contact synchronization. Permissions such as reading contacts, directly calling phone numbers, recording audio, and accessing network connections fit a calling and messaging service rather than a simple utility. Because the app offers subscriptions and credits, it seems aimed at ongoing phone-number use rather than a one-time tool.

  • Make calls and send SMS from the app

  • Manage voicemail and contact sync in one place
  • Place international calls with available plans or credits

Best for:
Second number users Work-life separation Privacy-conscious callers Frequent travelers International callers
