After a prolonged deliberation, the Mobile Number Portability has been tabled on the Indian Telecom space and it is set to liberalize the final frontiers of competition in the Telephony space. Subscribers have been unwillingly tied on to service providers irrespective of deteriorating service standards, thanks to locked in number series per provider. Now MNP is going to change that all for good. This paper explains the underlying MNP technology and its impact to the telephony ecosystem. This paper introduces the concept of number portability, explains its different types and benefits, and the technical, operational, and economic issues that might arise out of its implementation in India. The specific issues such as ensuring tariff transparency, the National Numbering Plan, and regulating porting charges, etc. have been raised and will need careful consideration. This paper discusses service provider number portability (SPNP), as SPNP is the primary form of number portability that promotes competition among the mobile service providers
