This facility has been available on BSNL network for both 2G and 3G mobile Internet plans but the same was stopped in February, the company said in a statement.
"This new facility will be applicable for all the GSM 2G and 3G prepaid mobile customers of all BSNL circles across India," the statement said.
To cash in on high demand for 3G services, BSNL is gradually introducing new 3G mobile Internet plans at prices lower than the industry.
"BSNL recently introduced Rs. 68 Data Special Tariff Voucher (STV) which allows 1GB 3G Mobile Data for 10 days, never given by any other operator at this cheapest rates in the present market," the statement said.
The mobile data carry forward facility of accumulation of unutilised balance data usage in BSNL prepaid plans will also be applicable for all the customers of normal data STVs and longer validity BSNL 3G data plan schemes.
"Quality of service and customer satisfaction is our top priority and transparency makes us different from other operators," BSNL Director for Consumer Mobility, N K Gupta said.
