If u see fiber map, number of areas they are covering have increased. I guess many lcos don't want to upgrade to excitel fiber coz either they have their own fiber infrastructure or they don't want to invest in fiber due to initial high cost. For users Excitel Fiber is big upgrade but for lcos its not as it is not increasing revenues, only benefit is stable network and low maintenance cost in long term. Jio and Airtel will change this mindset for sure otherwise u can't survive now. Its the reason my lco took excitel fiber although he was unwilling for the same since start.
