A collect call in Canada and the United States, known as a reverse charge call in other parts of the English-speaking world, is a telephone call in which the calling party wants to place a call at the called party's expense.

Collect calls were originally only possible as an operator-assisted call, but with the introduction of computer-based telephone dialing equipment, it became possible to place a collect call without using an operator. Automated reverse charge dialing eliminated a service that could be provided, at a higher fee, only on operator-assisted connections: the person-to-person call, in which there is no charge unless a designated person is available.

In June 2019, the largest mobile service provider Safaricom started rolling out reverse call services to all its customers. To access the service, a customer has to dial # before dialing the desired number.

The recipient could then choose to accept the charges for the call by pressing 1 on the dial pad. Safaricom said that the cost of reverse calls is the same as the cost of normal calls.^[11]
