BSNL Tamilnadu just a while ago has slashed WiMax broadband internet tariffs for heavy usage consumer who run out of Data Usage Limit.

*Additional Data upto 5GB = Rs 0.20 / MB
*Additional Data over 5GB = Rs 0.10 / MB [Works out to Rs 100 / GB]

By Additional Data they mean, data that is over the limit provided in your WiMax Plan

Suggested WiMax Plan

Rs 750 / Month 4 GB Download at 4 Mbps Speed

Or

Rs 750 / Month, 512 Kbps Speed and Unlimited usage. In this case the additional Data tariffs discussed here won't apply.
