I forgot to recharge my account yesterday which was due date and strangely noticed that many channels like India TV, ABP News, R Bharat, Mastiii, etc. were still running smoothly this morning
I guess airtel will also provide some FTA chs. as a complimentary combo and these will not cost anything + not be counted in any slab including introductory one. Waiting for @Arsh bro to give more information, in my opinion they r still finalising list and testing activation.
