Correction: Jio Fiber actually provides the most popular and relevant OTT subscriptions bundled with their fiber & airfiber plans. They are providing 15 OTTs currently with the upper tier plans and 13 OTTs with the lower tier plans. Until a few months back, they had 18 bundled OTTs total.
When it comes to bundled fiber + OTT services, no one can beat Jio in it because they are available throughout India and providing lesser but most important OTT services. Whereas others are providing many useless/less known OTT subscriptions which many might not find interesting.
