You are upset with your service provider, here is an opportunity to change without changing your mobile phone number. Number portability provides consumers with the ability to change service providers, locations, or service types without changing their telephone numbers. Prior to number portability, changing service providers required end-users to accept a new number or if available, use remote call forwarding.
Lot of hurdles to cross before effective implementation of the facility. A variety of back office systems also require changes to accommodate NP, such as billing, inventory and operational support systems.
Other issues to consider as they ramp up for full porting implementation include: intercompany testing; telephone directory listings for customers who opt to switch their wire line service to a wire line provider and wish to publish directory information; troubleshooting; interconnection agreements; cost recovery and bill reconciliation, as well as the Inter carrier Communications pre-porting process.
You have to pay Rs 19 for the change. Does it mean the end of all your sorrows with your mobile phones. Wait and watch
