is Mobile number portability ?
Mobile number portability (MNP) enables mobile phone users
to retain their mobile phone number when changing from one mobile network
operator to another.
In India this service is available for both postpaid and
prepaid subscribers and on both GSM and CDMA technology platforms but only
within your own telecom circle. Inter circle mobile number portability is expected to start from
The procedure is that you send an SMS to 1900 like PORT XXXXXXXXXX. You will
get an SMS reply containing an eight digit alpha-numeric code and an expiry
date for it. Then you approach the new service provider with this unique
porting code. Carry ID and address proof, a photograph and an application
with the unique code & your mobile number. You have to complete this
process within the expiry date. New operator will take request to mobile
portability clearing house. Clearing house will get your number deactivated
from existing provider and activate new one. You'll then get SMS from new
service provider mentioning date & time when porting will take place. Your
phone will go out of service for few hours while switching.
The cost of porting is Rs.19. A subscriber must remain with a service provider for
at least three months.
