Mobile Number Portability (MNP) is a way to enable mobile phone users to change from one mobile network carrier (the donating network) to another one (the recipient network) while retaining their mobile telephone number.
- How does this service technically work?
- After the portability of a number has been performed, how the routing of the calls is managed?
- Is a "ported number" dependent on both donating network and recipient one to work correctly? If the donating network is affected by a fault, does the ported number continue to work?
