Under the scheme, anyone who buys the mobile phone for Rs 3,690 will get a cashback of Rs 900 after 1.5 years and Rs 1,200 after another 1.5 years.
However, the person has to use the specified Vodafone number on the device and recharge at least Rs 150 per month without fail.
The recharge can be done either cumulatively or as a one-time recharge.
The cashback amount at Rs 2,100 is higher than the Rs 1,500 that its rivals offer.
The cashback brings the device’s effective price down to just Rs. 1,590, Vodafone said.
The bundled offer can be availed up to March 31st, 2018.
Users will receive the cashback in their M-Pesa wallets, allowing them to recharge, pay bills, transfer money or withdraw cash, it added.
