MTNL is a sister concern company of BSNL and comes under Central Govt… The customer base of MTNL is nearly 5.92 million. And from past few years the graph is going down even if the Indian Govt. is spending too much of huge amount to uplift the customer base, but still the graph is going down and the main reason is their “GREAT SERVICES”. The MTNL lineman don’t have enough idea to configure even a modem and to solve a single complaint they take nearly 1 month or more because the don’t have enough workforce and the coverage area is very big. And when you see the MTNL exchange you become shocked to see their exchange, made of HUWIA equipments, and when you see the AIRTEL exchange you will find Ericson equipments just because the cost of HUWAI equipments are nearly half then Ericson.
Basically they have two type of exchange one is for 256 Kbps and one for above 256Kbps, if you buy plan for above 256 then you may get good response because for that only they use Ericson exchange.
I don’t know why the Govt. change the plan to get more customer and spend a huge amount in ads, the salary of lineman is nearly 15000/-, I think this is a total waste. Customers are very much frustrated from MTNL. If you visit the MTNL exchange you will find many customers shouting on the Area Manager. MY personal experience with MTNL was pathetic and now I switched to another services provider and now I am very much satisfied.
