Tata Motors is offering 50 Rs of free talktime only for Airtel users. I have not tested it since I don’t have any airtel sim card. But you can give it a try.
Procedure to get Rs 50 free talktime
1) Visit the Tata motors page using this link and you will see an option to book a test drive.
2) Now fill your full name, email id and most importantly your Airtel mobile number (prepaid).
3) Now, you will get the call from customer care to confirm the test drive.
4) After confirmation, your Airtel number will be recharged with 50 Rs.
