I called BSNL customer care (in Kerala) and customer care executive informed me that BSNL Broadband doubled the FUP speeds to 1 Mbps for all Broadband plans. Yesterday, One of the major news paper in Kerala displayed an advertisement about BSNL Broadband's new FUP speed.
Unfortunately I'm getting only 800 kbps speed even before FUP instead of 2Mbps speed. I registered a complaint via customer care executive and she informed me that the technician will check the speed and rectify the faults.
