Cofetel has revealed in statement that it has published a final version of number portability (NP) regulations. The regulations are due to be published in the country’s official gazette and will come into effect 165 days later. Cofetel previously said it expects the regulations to come into effect by February 2008. The watchdog has decided that operators can not pass the cost of implementing the technology required for NP onto subscribers, but can charge a one-time fee when a customer switches to their network. That decision means the bulk of the cost of implementation will lie with the operator. Telmex has said introducing NP could cost it USD61.4 million. BNamericas states that adopting NP regulations is one of the conditions in the convergence agreement in order to allow Telmex to offer TV services. The regulator sees NP as a way to lower telephony rates and improve services. According to BNamericas, Mexico would be the second country in Latin America to implement NP after Puerto Rico. Regulations for NP are being considered in several other countries, such as Chile, the Dominican Republic, Panama and Colombia.
