Are you fed up of your network provider’s poor services? If, yes then change your operator right now without changing your number. Now you must be thinking how to port mobile number? It is very simple, just request the preferred operator to provide you their services on your current mobile number. This process is known as Mobile Number Portability.
The portability process is very 
simple and you need to follow certain steps for that. First of all, you need to send an SMS in a particular format –eg., PORT 9999787878, to 1900. After this you will get an SMS in reply that will contain a Unique Porting Code (UPC). After receiving this code, you have to call your preferred operator and they will send an executive to you who will take your UPN and ask you to fill a form for MNP. The executive will also ask you for a valid id proof and address proof and then they will apply the necessary process. After your MNP request is approved, you will get an SMS containing the time and date when the porting will take place.
Generally applying for MNP is an easy process but there are certain challenges which are faced by the users. One of the major issues is the time involved in it. According to rules, the process must be completed within 7 working days of applying, but it takes long and sometimes the number is not ported even after 15 to 18 days. Further, when the process takes place your phone may be dead for 2 to 4 hours and you are not allowed for any incoming as well as outgoing calls.
There are some charges i.e. of Rs. 19 (plus other charges) as well that you have to pay for MNP. Apart from this, if you have switched your operator through NP, then you cannot apply again for it unless 90 days of portability have been completed. Further, your PORT out request sometimes also gets rejected by the existing operator because of some “contractual obligations”.
Solution: The Telecom Enforcement Resource and Monitoring (TERM) Cells observe such matters related to MNP. If you face any such issues, then you can file your complaints by making phone call, email as well as can go personally to the office for the same. Further, you can also call the nodal officers to resolve such issues.
