  • Here is a detailed procedure for CDMA to GSM Number Portability in India.

    UPC Code: At first you will have to get a Unique Porting code (UPC). For it send an SMS to 1900. You will get an Unique Porting code (UPC).

    Example: PORT your mobile number

    Fill application form: After getting UPC code you should go to your nearest retailer (Airtel/Idea/BSNL/Tata etc..). You should ask about the application form related to mobile number portability. In this form you will have to fill your personal details and UPC Code.

    Documents Required: When you are filling your form you will have to submit the following documents:
  • Identity Proof (PAN Card/Voter ID/Passport etc..)
  • A recent Passport size photograph
  • UPC Code
  • Copy of your Address

    Get a new SIM: When your procedure related to filling your form is finished, you will get a new SIM which you will have to replace in a GSM phone.

    You will receive a SMS: You will get an SMS from your new provider to your old provider SIM. The message will tell you the date and time when you will get the service from your new SIM.

    Use your new SIM: After the time that you got in SMS you can use your new SIM with the services of your new provider.

    Note(1) The charges for Porting CDMA to GSM - Rs.19.
    (2)Waiting time – 5 to 7 days
  • Yes, MNP from CDMA to GSM is possible in India. The main aim of MNP is to continue with the same number while changing one operator to another irrespective of network technologies. (CDMA/WCDMA/GSM etc.)

    Here you need a new handset as your previous CDMA handset will not work with new GSM SIM.

    As mentioned by Ekta, please follow the process and get it done.

    With Best Regards,
