Yeah, Meanwhile. Jio and
Tata is deploying lines overhead.
There is another reason, Airtel wants to upgrade is because their copper lines now have moisture on it which can't sustain for coming years anymore. Overall, they are forced because of competition, technology advancement and requirement of the customer.
Whatever it is, Airtel FTTH is the best you would wish for.
Same Day Fix.
You get what you pay.
Most Stable
Better Hierarchy in customer support. (Reaching to Nodal Team means risk of job for ground-level team).
Stable Routing.
Jio doesn't have a lot of stuff from above specially Routing.
Airtel very well understands that now if they don't upgrade their tech, they will start loosing customers to other ISPs very fast. Since, a lot of people don't want landline anymore if they get mobile network at their home.
So moving from Airtel to other ISPs is easier on customer side.
At the end, it boils down to the MCD's approval for the deployment. Airtel is ready to do full FTTH Delhi Wide.
