I am a subscriber to essar cellphone in delhi and I would like to share my views with others that better not to go for this. I feel they are running thier company by stealing little money every time from the customers. belive me once I had rs.22-00 balance on my handset and that time without any information the essar stopped services to my cellphone. then I called up their customer service center to complain the matter but rather listening to my complaint they said that the handset shows only approximate values/balances and not the exact figures but still difference of rs.22-00 .. I donot buy this. even worst was that after charging afresh I again got rs. 10-00 less then what I was supposed to get .. again I called up their so called customer support and I was told that might be your balance before recharging was in minus rs. 10-00 and thats why now they deducted the minus amount... can you buy this theory...if yes, then only go for SPEED
