Research firm Analysys concludes that government-sanctioned mobile number portability has for the most part failed in the majority of companies that have implemented it. Analysys' research came up with few examples where more than 10 percent of mobile numbers of have been ported from one operator to another. The firm cites the expense involved with moving numbers, long delays in the process and a simple lack of awareness among consumers that portability is available. Analysys also found that mobile number portability does not necessarily increase long-term churn rates or cause price competition. Good news for operators. Article
