How to get a 900 number
Choose whether to offer a live-call or a recorded-call service.
A 900-number company can forward calls to you so you can answer the phone personally or you can choose to have a recorded message waiting for your customers.
Choose a billing plan.
You can choose whether to charge your customers per minute or a flat-rate fee when they call. Pay the set-up fee and agree on a monthly maintenance fee.
