MTNL Mumbai has introduced a new 4999 Unlimited plan for Triband users. The rental for this plan is Rs. 4999 per month, with unlimited access to internet for the month at 2Mbps speed. We have seen MTNL launch some incredible affordable offers lately in Mumbai but this offer comes as a surprise when almost all providers are decreasing their prices to stay in the competition. Customers would want to try MTNL 3G unlimited plans which gives 3.1 Mbps connectivity instead of the static broadband connectivity at higher cost. Time for a reality check, huh?
