MNP-o-phobia and service providers

Mobile number portability or MNP, as we all know is what that helps customers to switch operators without changing the existing number. The service presently available across the globe (minus India obviously) allows the customer to change the service provider, if he feels discontent over the existing or if somebody else is offering a better service, and also letting him free of the hassle of spreading the 'change of number news' amongst his contacts. Moreover, MNP could be done irrespective of whether it is a GSM network or a CDMA network. Telecom Regulatory Authority of India (TRAI) have divided the servicing area into two zones and has given license to two companies to carry out the MNP operations: MNP Interconnection Telecom Solutions (MNPITS) and Syniverse Technologies India.
