Mobile Number Portability: How to Port Mobile Number in India, Charges & Other Details

By -

mobile-number-portability-india Those who are still unaware about Mobile Number Portability (MNP), it is a  service using which a mobile  phone subscriber can migrate from one operator to another without having to change his/her mobile number. For example, you can opt to choose for Voafone services on your Airtel number or vice-versa, courtesy MNP.

As of now mobile number porting can be done only within the same telecom circle and not on inter-state or inter-telecom circle basis. Meaning, you can only port the number in the same state/circle where the mobile number originates. But good news is that, inter-state MNP has already been approved by TRAI (Telecom Regulatory Authority of India) and telecom operators will be soon introducing inter-state MNP services too.

How to port your mobile number?

Its simple, all you’ve to do is

  • Generate UPC (Unique Porting Code)  from the same number that you wish to port (procedure mentioned below)
  • Clear all your pending dues (if your’s is a post-paid mobile connection)
  • Visit a mobile outlet or nearby store of the new operator along with:
    -The UPC code thus generated
    – A photo and a copy of your identity proof
  • Pay the requisite porting fees of Rs. 19/-
  • Get your number ported to new operator within the stipulated time frame of 15 days

Generating UPC for Mobile Number Portability:

  • Send an SMS: PORT<space>Mobile Number (that is to be ported) to 1900
    For ex. PORT 9812345678
  • Your existing operator will immediately provide with an 8 digit alpha-numeric porting code that you need to submit to the operator you wish to opt to along with relevant documents. (The unique porting code will be valid only for 24 hours)

FAQs related to Mobile Number Portability:

  1. Can I migrate a number from one state to another via MNP?
    Unfortunately, currently you can only migrate to another operator within the same circle. But inter-state portability will be launched in India very shortly.
  2. What are the minimum and maximum time specified for porting number from one operator to another?
    Porting time could be anything between 24 hours to 4 days.
  3. What are the charges for Porting to another operator?
    As mentioned above, service providers can charge a maximum of Rs. 19 for porting a number .
  4. Who is eligible for availing mobile number portability?
    Any customer having a mobile number older than 90 days can migrate to another operator with the same number. He/She will have to wait for another 90 days before being able to port their number again.
  5. Will my number be dead during the porting process?
    As per the details available, a number will remain dead for 2 hours approximately during the porting process. Fortunately, the 2 hours downtime will be between 10 PM and 5 AM IST.
  6. Can I migrate my post-paid number to another operator with prepaid services or vice-versa?
    Yes, that can be done once you clear off all pending dues with the current operator.
  7. Will my prepaid balance carry-forward to new operator?
    No. All remaining balance on your mobile will get lapsed and will not be carried-forward to the new operator. Thus, its advisable to completely use the available talk-time before moving to another operator.
  8. Can I port my CDMA number to GSM operator or vice versa?
    Yes, with the introduction of MNP, moving from CDMA to GSM or vice-versa is possible too, but your existing mobile will be rendered useless if you opt to move from CDMA to GSM technology.
  9. Can I port my landline number to a mobile service provider?
    Porting a landline number to a mobile operator is possible in countries like US though, for now, Indian govt. has planned to launch MNP only for mobile phone users. India might witness landline number portability in the future.
  10. Will I get any freebies from the operator I am porting my number to?
    During the launch of MNP in India, various freebies were offered by new operator to welcome its customer. Do check with the new service providers’ customer care if any welcome offer is available currently.

    I am not getting port number from my service provider which is Reliance CDMA. I had SMS to 1900 two times from my number but did not get reply. How much max time it takes to get reply from service provider?

    Also i am not getting the meaning of (The unique porting code will be valid only for 24 hours) in above paragraph. Should anybody can tell me ?

    • Vaibhav, call complaint helpline @ 198 and ask them for your porting code. They must give. If not, let me know.

      Regarding UPC validity – the code keeps changing. You can port your number only with a valid and active UPC.

        Deepak, i am suffering the disadvantages of CDMA phones now. My cell mike is not working. So can’t communicate with customer care (rather anyone). Due to CDMA can’t use friend’s cell (all are GSM). Only SMS is the option that is working. But not getting the reply from 1900.

  10. i want to port out my number from MTS (CDMA) to some other gsm provider, however the CDMA handset that is provided by MTS does not work so i cannot send the port sms from dat handset, how can i start the port out process without sending an sms….

  11. Hi Deepak, thanks for the info. I want to migrate from Reliance CDMA. My only reason is that i need a more savvy handset, which is possible only if i go the GSM way. I am overall happy with the service and conectivity with Reliance so i m worried that the migration might lead to a different set of problems ifi choose the new servie provider incorrectly. Can you recommend a good GSM service provider based on track record? I travel widely within India so connectivity on the go is important. As is overall operating cost. Random inquiry seems to show Airtel as an overall good bet. What do you say.

    • Yes, Airtel, Reliance (GSM) or Vodafone should be the best bet considering they have license for almost all telecom circles. All the best with the migration! :)

  12. @deepak.. thank u for all d informations.. As per u said above, from today dats 20 jan, d MNP wil be available pan india.. so now can i change my karnatak vodafone number to tamilnadu airtel or vodafone only.. plz do reply..

    Is MNP not yet activated for Delhi people ? Should I continue with the nasty service provider further?

  14. Seems you did some mistake while sending the SMS.
    Please try again by sending
    PORTspaceMobile number
    and send to 1900
