Due to poor visibility (zero ad) of BSNL’s ongoing Plans and offers among mobile users in TN (including Chennai) and absence of Uninor, Now TN based private GSM users are forced to paying 39% to 43% more for one month local mobile calling pack and also 300% to 400% paying more for every local landline / fixed line call per minute.
Apart from this, private network had decreased their STV – special tariff voucher’s validity from 30 days to 28 days, here are the comparison table: (only local calling pack in TN are taken for).

Most of the special tariff vouchers (voice calls) from Private networks are always given special benefits only for mobile calling; which pack is not support to landline/fixed line calls, so that they have forced to pay headline tariff or often called base tariff is Re.1/min to Rs.1.50p/min.
Private network has differentiated like on-net mobile calls, off-net mobile calls and fixed line calls. But BSNL has always differentiated like on-net (mobile/landline/fixed line) and off-net (mobile/landline/fixed line).
Many of the BSNL’s plan vouchers and special tariffs calling vouchers are supported / included on-net calls means (local and national mobile/landline/fixed line) and off-net calls means (local and national mobile/landline/fixed line). Due to this private network mobile users are forced to a call landline, it has charged 300% to 400% more than what BSNL Mobile users pay. So, Those who are using local voice calling pack from private networks they are have paying more than BSNL user.
