Works for both prepaid and postpaid mobile connections. You will have to make a mobile number portability request to your current mobile operator.
Steps:
1. SMS PORT <your Mobile Number> to 1900
Example: PORT 9898989898 to 1900
2. Ignore the UPC (Unique Porting Code). It will expire automatically.
3. Within 1-2 days you will get a call from customer retention department asking for the reason. Tell them “other” network (airtel, reliance, vodafone, etc…) is offering plans with lower call charges and more data usage. They will make an offer so that you don’t change your mobile operator. Accept it.
4. If you don’t get a call – it does not matter, because you lose nothing.
