Effectiveness: This application helps to choose the best option and reduce expenditures by determining the operator which the number was ported to.

The app checks whether all the numbers in your phonebook are connected to "Mobile Number Portability" (MNP) * service. If the dialed number is connected to the MNP service, you can save money by calling the number of the relevant operator.
For example: If the dialed number is ported from Azercell to Bakcell, you will save money by using your Bakcell number automatically during the call.
