A guy has asked me this question "How to Change from Reliance CDMA to GSM under MNP?". So here is a detailed procedure for CDMA to GSM Number Portability in India.

1. Send an SMS: PORT<space>Your Mobile Number and sent it to 1900. You'll get an Unique Porting code (UPC)
   

   Ex: PORT 9885098850
   

2. Goto your nearest retailer of your choice (Airtel/Idea/BSNL/Tata etc..) and ask for an application form in which you need to fill your details along with your UPC code received (in step 1).
   

   Proofs Required: UPC Code, Copy of your Address, Identity Proof (PAN Card/Voter ID/Passport etc..) and a recent Passport size photograph.
   

3. After all the process has been completed, the retailer will hand over a new GSM SIM to you which you'll need to place in a GSM phone.


4. Next, you'll get a message from your new Operator (the one you've chosen) to your old operator's SIM, the details regarding the porting date and time i.e., when you can use your new SIM card.


5. After the specified time, you can use the new SIM in your GSM mobile with new Mobile Operator serving you.
   

Note: The charges for Porting CDMA to GSM is Rs.19. Waiting time would be 5-7 days before your CDMA number is completely ported to a new GSM number.

This is the same process for all CDMA numbers (Reliance and Tata Indicom).
