What the OnPhone app does
OnPhone lets you run two separate phone numbers on a single Android device without purchasing an extra SIM. You can toggle between the lines to separate personal and work calls and messages.
Device compatibility and requirements
- No rooting of the phone is required for the app to function.
- The app is compatible with any Android handset — no special hardware needed.
- You do not have to insert a second SIM card to use the second number.
- Setup is simple: install the app and follow the on‑screen prompts to get started.
Installing and configuring a second number
- Install the OnPhone application from your chosen store or APK source.
- Launch the app and select the option to create a new line (usually shown under your primary line).
- Pick the country you want the new number to belong to and confirm your selection.
- Finish the setup steps shown in the app; once complete you’ll have two active numbers to switch between.
Making calls and switching lines
- After setup, choose which number to use for outgoing calls or messages from within the app.
- You can call any of the numbers that appear in your OnPhone contact list or call log.
- Switching between your personal and business numbers is done inside the app interface with a tap.
