In accordance with a first aspect of the invention there is a system (10) for facilitating communications between two parties comprising a first party (12) having positive credit with a communication facilitator (16) and a second party (14) having insufficient credit with the communications facilitator (16) to initiate or continue communication. The first party (12) sends a first communication message (26) to a first destination address (18) associated with the communication facilitator (16). The communication facilitator (16) includes the first communication message (18), or at least a portion thereof, in a second communication message (28) which is sent to the second party (14) via a second destination address (22). The second party (14) replies to the second communication message (28), the reply being received at the second destination address (22)—the communication facilitator (16) thereafter operates to forward the reply to the second communication message (28) to the first party (12) and charge the first party (12) for the first and second communication messages (26, 28).
