You don’t need to cancel MNP request. Just don’t port, if you don’t want to even after getting the code.


Can existing service provider delay the number portability process to new service provider.?


I placed a porting request on 7th March. My bill due date is 16th March. I paid the bill on 12th March and cleared all outstanding with current operator. Then also they rejected my Porting request saying bills due at the time of placing the request without informing me. Is that legal?
