Abstract: The invention relates to a method for preparing an optimal alternative billing plan for mobile telephony users managed through a call center, which is applicable to the recommendation of an optimal telephony plan to the customers of an operator, considering the consumption of the customer, the risk of the customer migrating to another and the market strategy of the operator. It comprises the estimation of the real bill of a customer during a time period covering the last M months, a simulated estimation of the bill of the customer using any generic plan based on the mean traffic of the last M months, applying a simulation algorithm and the estimation of the churn risk of a customer according to the value of the said customer, the value of the operators on the market, number of better offers, number of the customers which he calls per operator and the simulations performed with the generic plans, applying an estimation algorithm.
