This mobile operater is average .
The main disadvantage this mobile operator is validity date .if we rechrge with10, 20, 30 we will losed in one week when we did not recharge with big amounts.it does not have any offers like 10paisa per minte.
The main advantage of this operator is we select the 5contacts and send thise numbers to the 57777 I did not sure .then it will cost 10 paisa per minute for bsnl opearatorsand 30paisa per minute for others.but bsnl data offer is good when we compe to other mobile operators.overally it is good
