OK, here goes. Just confirmed from a known source who has opted for these plans. FUP applies to all old connections. However, as part of BSNL Anniversary celebrations, new connections booked this month have no FUP for 2 months only, then FUP applies.This is still great. 16Mbps till 40GB, then 4Mbps beyond for 1499 is awesome!For comparison, Beam also has 1660 plan with 15Mbps till 40GB, then 4Mbps.In contrast, my Tikona has 4Mbps true unlimited at 1249 bucks!
