I have just changed my plan to 512 Combo. When the plan was launched many found it very very xpensive, but I dont really think so. With 512 combo I have to pay them 2000 Rs. But since its a combo plan I dont have to pay phone rental (hope so atleast) now so that saves my 250 rs and effectively I have to pay 1750. But also I get 500 free calls as compared to 60 on my current plan so difference is 440 calls which is worth Rs. 350. So effectively I have to (1750-350= Rs1400) for 512 kbps unlimited connection. Now Airtel costs around 1499 Rs. for same plan I know MTNL is not as good as Airtel but its not as expensive as ppl have calculated, atleast for those who already have MTNL telephone and are paying the rent. I had to call CC atleast 4 times to get my plan changed and couldnt coz their server was down. Everytime different person picked up the phone and none knew if there's any plan with 512kbs unlm speed exists. AMAZING!! . My plan will come in to effect on 1st June and i have got my fingure crossed to see speed and sync rate.
