Once you have signed up for the OnCall service, simply dial the toll free number we provide you with. It's that simple! Instead of a cold machine spouting a number on the other end, you’ll be connected to one of OnCall’s helpful personal concierges. Your concierge will find the information you’re looking for and not only provide it to you directly, but will also follow up with a text message to your phone so you can keep the information handy.
