BSNL Rs 999 Plan Gets Additional 30 Days Validity Extension As mentioned above, BSNL reduced the validity of Rs 1,188 Marutham plan to 300 days in Chennai & Tamil Nadu circles. The same treatment has now done to Rs 999 voice-only plan as well but in a positive way. Talking about the benefits, users get unlimited voice calling capped at 250 minutes per day to any network within India for a period of 240 days. But customers recharging between February 15 and March 31 will get 270 days validity. Users can also make voice calls in Mumbai and Delhi circles with the Rs 999 plan. The plan also comes with BSNL Tunes subscription for two months. Sadly, BSNL is not providing data and SMS benefits with Rs 999, which is underwhelming. Even the Rs 1,188 Marutham plan offers just 5GB of data benefit and 250 minutes of voice calling for 300 days. But if you are someone who prefers just voice calling benefit, then opt the Rs 999 plan. Also, do make a note that the Rs 999 plan is not available across all the telecom circles where BSNL is operating. BSNL Rs 1,188 Marutham Plan vs BSNL Rs 999 Plan BSNL relaunched the Rs 1,188 Marutham plan on a promotional basis very recently. The plan now provides 250 minutes of voice calls every day along with 5GB data for a period of 300 days. On the flip side, the Rs 999 plan offers just 250 minutes of voice calling per day for 270 days. Both the plans are available in just Chennai & Tamil Nadu telecom circles.
