Telecom regulator Trai today recommended that mobile number portability be fully implemented across the country within six months to allow subscribers to retain their numbers even when they shift from one service area to another. At present,MNP is available only within the subscribers service area. When MNP is implemented fully,subscribers in Andhra Pradesh,for example,will be able to port their numbers to Karnataka,Maharashtra,Haryana and so on. Earlier this year,Trai sought comments from stakeholders on the method that should be adopted to implement full MNP and the amendments required in existing regulations,among various other matters. After an examination of various issues,Trai today released the recommendations on full MNP, said a statement from the authority. Telecom service providers will be given six month for the implementation of full MNP,it said. The facility of pan-India portability will allow a mobile subscriber to change his licence service area (LSA) without having to change the number.
