This supplement is intended to assist interested telecommunication operators in developing prepayment guidelines. Since an operator’s decision to establish prepayment mechanisms is an internal commercial matter, the guidelines in the present supplement are voluntary and meant to be illustrative in nature. Their objective is to help operators formulate new (or update existing) prepayment guidelines according to their needs and to promote efficiency in account management.
