But here's the thing with BSNL's announcement. You get 2Mbps speed but only till your data-limit is not breached. In simple words, fair usage policy (FUP) the biggest detrimental to our internet package is here to ruin our day yet again.
Once you've exhausted your data pack, the speed reverts back to 512Kbps much to our disappointment. In many ways, BSNL has repeated history of being unclear with its proposition by stating the promise of aforementioned speeds (minimum) and totally skipped the part wherein FUP usage will bring you back to ground, in terms of speed.
This isn't the first time when BSNL has tried misleading its consumers, as communication on their part has more or less been found to be different in reality. It seems they haven't learned from their mistakes in the past, after all.
