Speaking about the first plan introduced by BSNL, the Maha Saver plan, it offers Rs. 220 talk time and 110 minutes of free BSNL to BSNL calling. Also, you can set a caller tune at no extra charges. Do make a note that this plan is valid only for BSNL users in Andhra Pradesh & Telangana.
Talking about the Rs. 485 tariff plan, it is valid for BSNL users in Karnataka circle. This plan gives unlimited voice calls to any network including incoming and outgoing roaming calls. It also gives 1GB data per day for 90 days, making it 90GB data for the period. The 1GB data works even on national roaming in BSNL and MTNL network.
Recently, BSNL launched the same Rs. 485 plan for Tamil Nadu users, and hopefully the operator launch the same plan across the country in every circle.
BSNL has been aggressively launching circle-specific tariff plans in recent times. The operator is already offering a Rs. 429 plan that gives benefits of 1GB data per day and unlimited voice calls for 90 days.
