Reachability and devices

Smart Messaging is device-neutral. You can call from the browser web dialer on any computer, register the number on a SIP softphone for iPhone, Android, Windows or macOS, or forward calls to any phone in the world. Incoming calls and SMS are unlimited, and the dashboard keeps call logs and an SMS inbox in one place, which is useful if several people on a small team share responsibility for a line.

Free versus paid numbers
Free app numbers keep costs at zero, which is great for casual calling. A paid number is worth considering when the number underpins something important, such as a business contact line or the recovery number for your messaging and email accounts.
