Q8. How can I port to a new Mobile Service Provider?
The steps involved are as follows:
[*]You will have to go the new Mobile Service Provider’s Service Centre or Authorized Dealer to request for porting of your Mobile number. Fill in a Service Registration Form and pay the porting fees for processing. (Presently some operators are not charging any fees for porting).
[*]The Recipient Operator shall ask the subscriber to send a SMS to Donor operator to request for UPC (Unique Porting Code) using short code
‘1900’ from the Mobile number which is sought to be ported.
[*]The SMS text for requesting UPC by a subscriber shall be the word ‘PORT’ followed by a space followed by the 10 digit mobile number which is to be ported which shall be case insensitive. (i.e. it can be port or port etc.) (e.g. PORT 98160XXXXX and send it to 1900).
[*]Upon receipt of the SMS, the Donor Operator shall forthwith send back a reply SMS containing a Unique Porting Code through an automated system. Subscriber will fill the UPC in the application form for porting.
[*]In case the subscriber’s CLI does not match with the 10 digit mobile number. UPC shall not be allotted but a message shall be generated to inform such subscriber that the CLI does not match with the Mobile number.
[*]UPC allocated to a subscriber shall be valid for a period of 15 days from the date of request or such time till the number is ported out, whichever is earlier, for all service areas except Jammu & Kashmir, [color=#ff0000;]Assam[/color] and North-East licensed areas the validity for the UPC shall be for a period of 30 days from the date of request or till such time the number is ported out, which ever is earlier, irrespective of number of requests the subscriber makes,
[*]You will be issued a new SIM card by the new service provider
[*]Upon approval of porting request, the new Mobile Service Provider will inform you the date and time of porting. You are required to change your SIM card at the said time. In case of problem you need to contact the new Service Provider.
