Difference between 2G and 3G in India

While there is only voice transfer in 2G, 3G allows for data transfer in addition to transmission of voice
• The clarity of voice in 3G is significantly more than 2G, and there are very little disturbances
• 3G is a much more secure technology than 2G
• 3G makes available many more features for mobile users such as internet, mobile TV, video calls, video conferencing, mobile gaming whereas no such features are there in 2G
• One drawback of 3G is that it is not available in all parts of the country, whereas 2G is universally available across India
• 3G services are pricier in the country than 2G. But now the MSNL has reduced its 3G tariff to attract more customers
