BSNL DATA_BUNDLE_96 validity extension plans details

Hi,

I am using bsnl mobile and today I received sms saying my validity is expiring soon so now time to get it renewed. I generally use Rs. 36 validity extension plan which extends validity for 180 days with free 50 mb data for a month. But I also noticed this plan on bsnl portal with 365 days validity. But there is no details available for this. It only says it has 365 days validity but nothing else is given. And what is about data in it ? Does it give data valid for 365 days , what about minutes or what kind of plan is applied, is it per second plan or it is per minute plan or it is not changed and just validity is increased ?

Anyone has got any idea about this ?

You will have 500 GB data valid for 1 month.
You will have 365 days of validity
You will have base tariff what you were using.

But call customer care at 1503 from BSNL phone to confirm.
