Quo and Allo Offer Multiple Phone Numbers on One Device via VoIP

Virtual phone providers like Quo (formerly OpenPhone) let users add multiple phone numbers to a single smartphone without a dual‑SIM or extra hardware. Numbers are delivered over VoIP and work on iOS, Android, macOS, Windows and browsers, enabling separate personal and business lines.

Competing apps such as Allo target small business teams, adding features like call recording, AI‑generated call summaries, shared inboxes and an AI receptionist. Both services cover the US, Canada and other regions, offering flat per‑user pricing and easy setup.
