It seems that BSNL has now modified its double data initiative under which the company offered double data at the same price to its prepaid customers. Now, as per new details, the BSNL doubled data initiative would be a Diwali promotion; beginning on October 28 and ending November 5.
Basically, the BSNL Diwali Double Data initiative, as its name says, offers double data for the same price. Under the Double Data plan, there are multiple recharge options; higher the data opted-in for, higher the validity. The highest validity period offered is 1 year.
The lowest recharge denomination starts from Rs 68 which offers BSNL customers 2 GB data with validity of 1 day. Prior to the offer, data limit offered under this recharge was 1 GB. The highest recharge slab, which is Rs 4498, promises a staggering 80 GB data with validity period of up to 365 days.
Another notable aspect about this initiative is that customers who have already recharged for Rs 68 and enjoying 1GB data can recharge again with Rs 68 to experience 2GB worth of data. Tariff-wise breakup of BSNL's Diwali Double Data is given below:
Rs 68 – 2 GB data- 24 hours validity
Rs 155 – 2 GB data – 15 days validity
Rs 198 – 2 GB data – 28 days validity
Rs 1498 – 18 GB data – 1 year validity
Rs 2798 – 36 GB data – 1 year validity
Rs 3998 – 60 GB data – 1 year validity
