While telcos are fighting against the government over the reserve price for spectrum auction, the 3G war among the operators is heating up. After Airtel, Idea and RCom, Vodafone on Tuesday slashed 3G tariffs by up to 80 per cent.

Vodafone said that its 3G plans now start from Rs 25 for 25 MB data usage and go up to Rs 1,599 for 12 GB data usage. Under the pay as you go for pre-paid customers, the rate has been cut by 80 per cent to 2 paise per 10kb.

 Vodafone also announced there will be no additional charges for roaming on data usage. "Additionally, Vodafone will now allow its customers to use data from their bundle package while on net roaming across any location in India without any additional charge," a company statement said.

Vodafone said that its new `pay as you go' (PAYG) price plan for prepaid users is the cheapest in the industry. At 2 paise/10 KB, it is an 80 per cent reduction from the existing rate of 10 paise/10 KB, making it a plan tailor made for everyone".

"Our new PAYG price plan at 2 paise/10 KB is now the lowest in the industry, below the existing base rate of 3 paise/10 KB data plan," claimed a Vodafone India spokesman.

Last month, Bharti Airtel, Idea Cellular and Reliance Communications had reduced tariffs for its third generation (3G) high speed internet services.

"With the introduction of these plans, we aim at establishing a foundation for providing a 3G data plan for everyone, making it affordable to the masses in the country," Vodafone India Chief Commercial Officer Sanjoy Mukerji said in a statement.
