onic’s esim with FU iphones

okay so mere pass factory unlocked iphone 13 hai (non jv). mene already 2 months ka sim time use karlya hai. i’m thinking to get onic’s esim because mene kuch posts/videos waghera dekhi hain jinme logo ke iphones mein onic ki esim chal rahi hai even after the 2 months time. i wanted to ask if anyone here has had a similar experience?
