@Kick933 @C3PO might be better perrson to answer this as they were veteran in this field.
First of all don't be decieved by fiber and backhaul bandwith info, some user Anurag Bhatia has laid down the challenges of the backhaul here:
^^^then what does the gateway do? is it like having a store without any supplies .:silly: ...No. It allows them to provide international data services that only a few ISPs in India can currently offer. How they do that is up to them, whether it's purchasing bulk capacity on an existing cable...

Please stop making mere assumptions.
Without official data, users can only make assumptions based on their third-party observations like ping,speeds,jitter(which includes a lot of after effects of things going on in backhaul)
So most of my post will only be assumptions based on
my observations
a)
Constant Connectivity - even if not everyone utilizing 4 mbps+ , phone these days have lots of apps polling services, for rough calculation take 90 percentile usage of 1 mbps: 1mbps *100000 = 100 Gbps
b) Wireless bandwidth irrespective of 4g/5g cannot match fiber due to laws of physics and engineering challenges, yes 4g can provide
upto 100mbps but not to everyone even before it faces backhaul bottlenecks.
c) Load peak is becoming
symmetric : if load peaks it not just because of you
alone and for your isp only, suppose your friends are on group chat any message you post/receive, polling for that happens from their side too in passive mode and in active chat polling doubles for each user(so if you are on AIRTEL and sent 1 mbps worth data, your friends on IDEA, VODA, BSNL also consume that 1 mbps +overhead).
Now do the maths and you see exponential growth of usage.
d)Backhaul capacity is not evenly distributed, bottleneck at one place may amplify the effects for others
These are just my
opinions so take this with grain of salt.
