@nishantt6969 Same here. I had pre-paid 3 months for a 100mbps Airtel Plan which got activated on Dec 11th 2021..... Now today it's 11th March 2021, exactly 90 days....and today the internet should expire, but I am having exact same experience - 1Gbps Speeds.
How ever, here are the weird things with Airtel I observed
1. I am getting
Gigabit Speeds now.
2. First I got message in Feb saying my internet will be expiring on 11th of march, then from past 7 days I am getting message that it will expire on 12th of March, and suddenly yesterday on 10th of march, I got a message saying that it will expire on 10th oof march itself.
And now that's what probably happened and now the speeds are 1Gbps.
3. Airtel website displays bill cycle up to 8March with Due date of bill as 18th March but Due amount being -91.78 INR ( -ve one ) while the Airtel Thanks app shows Internet pack has expired and Rs 28 as Account Balance.
As I live in a Tier 2 City - Aurangabad ( Maharashtra ) - and the landline/VoIP feature doesn't work, So I can say I am on Advanced Rental Plan, and not postpaid bill cycle.
As others said, it maybe due to LCO's fault that internet stays active. But in my case I can confirm, that I am getting it from Airtel and not LCO because here's the long story short.
In my city, there is an ISP called Gazon Fiber or Gazon Communications. So I have been using it since 7 years now, the service was very good. I was using 1Gbps Plan since about 2018. The Prices were cheap - costed about 1000 Rs a month incl taxes, (no OTT apps), the services were also good.
Also this ISP had many other Sub-ISPs taking Internet from them which I got to know while talking with the installation team guys whenever they visited for providing new connection nearby or if the cable got cut.
But I started experiencing much downtimes in Lockdown as these Sub-ISPs had got many more customers, so I finally decided to shift to Airtel.
So when I opted for Airtel Xtreme Fiber, as you all know, the 1st payments related team was from Airtel.
The 2nd team who was doing the installation was from a Local ISP. This Local ISP was a Sub-ISP of my original Provider Gazon, which I knew. So I casually asked them if these people are still using Gazon. That is when those guys told me that now they were relying on Internet from Lease lines of Airtel and
Tata because they experienced the same issues of downtime.
So Clearly, in my case there was no such thing as LCO.
Then I asked these Guys if the OLTs are at offices of Airtel or other ISPs, ( bcause there's no big office of Airtel in my city as far as I know )
They told me that OLTs are located anywhere, not just office.
That is when I got to know, that these days there has been a lot of change. Now each tower has equipment of multiple service providers like VI, Airtel, Jio , BSNL. Earlier the towers had a single generator, now even that has changed, there are huge batteries in the cabinets of Jio/ Airtel or others and as well as this generator. Usually majority of Towers in India are built by Indeus Towers. Here's a Video explaining about
Jio's ODC equipment. It's much convenient for them to Wire it all at the same place. And here's
another video taken at some tower, where OLT's are kept
So maybe they also lease the underground fiber cables between each other as the requirements change. So for Big telecos, its cheaper to have OLT at nearest Base Station of Tower and connect the nearby area, but they still need a sizeable amount of customers. But they save much on cabling long routes over the ground ( which is I guess not legal ) and thus have higher reliability.
So I guess, its some fault with Airtel's System.
