Bharti Airtel has restored its 28-day ₹299 prepaid plan after net customer additions slowed in Q2FY27, while shifting focus to upgrades, postpaid and other levers to boost ARPU. Bharti Airtel has brought back its 28-day, 1 GB-per-day entry-level plan costing ₹299, which it withdrew from the market in August, according to the company’s website, as the quarter ended September showed a slowdown in net customer additions.
