A method of operating a telecommunications device wherein the telecommunications device is used to detect an outgoing call from a calling party to a called number. The calling number is used to determine whether or not the calling party is a universal service user. If it is determined that the called number is among a class of numbers exempt from charges, the call is connected. A determination on the sufficiency of funds in a pre-paid account is made. If it is determined that there are insufficient funds in a pre-paid account to cover charges associated with the outgoing call, a message is generated and sent to the calling party or a third party requesting authorization to charge an additional fee for connecting the calling party with the called party. User input is received from the calling party, indicating the calling party's authorization of such charge. The connection between the calling party and the called party is made. In an alternative embodiment, costs for providing data communications between an initiating party and a universal service user are calculated, in response to a request by the initiating party, in accordance with the network elements required for a requested quality of service.
