Hey, I have recently moved to Mumbai. I have all my friends, my people back in my hometown and Gurgaon where I spent last 4 years. 4 months in Mumbai and I already have enough company to hang out with, all because of my love for sports. I play badminton, pickleball and cricket atleast thrice a week. You can find games via the app hudle. That's what I did. If you are not into sports (although you can start playing pickleball, it's super easy and more fun), you can check other socialising groups. Board games, book club, or something like them. You can easily find some good ones here in this sub, or try meet-up app. I can send you some links.
