on the latest pdf the speed of the Rs 900 plan is
4 Mbps upto 8GB 512 Kbps beyond 8 GB T/A
and 850 Rs is
1 Mbps upto 8 GB, 512 Kbps beyond 8 GB
if we compare both the plan have equal cost as they give 400 and 350 minutes free calls...
but wat is the meaning of that T/A on BB 900 plan..
and which one will u prefer....
