Call Drops - Airtel issue. Set to 2G only - not an issue on vodafone.

I have had a set of Call failures on Airtel number, these have been happening and I decided to check some details.

Call Failure on Airtel, Sigh! :

Voice coverage on old Operators(Vodafone, Idea, Airtel) is better in 2G than on 3G or 4G towers. So decided to force 2G as preferred on Iphone 5s for airtel sim. Checked settings and there is no option which allows 2G on a Airtel sim. see screenshot 2:

No option to select 2G on Airtel, why ?:

Now checking the same setting on Vodafone sim this allows setting 2G as preferred sim on iPhone 5s.
And there I have no call drops when Vodafone sim is used.



See the full signal when Vodafone 2G is selected and that just works. No call drop on my secondary number.


Now decided to reach Airtel on all of this, But they aren't able to understand the issue. Reached them on twitter - they checked and still not able to root cause or provide the solution.

For now I will just use Vodafone as a temporary secondary sim.

Facebook delete Account ? Mostly not, but do fix Apps permissions access

So Elon Musk deleted Facebook accounts for his Companies. So i decided to check what more privacy thing is available that I can take care in my Facebook account. Since all the Leak of user data had happened thru the developer Apps - I decided to check which Apps have access to my Facebook data. Funny(/Scary) to see I had some stupid app back from 2009 also still having access to my Friends list and Pages I like. Why they need this.

Removed all the Apps and kept to bare minimal Strava and few more.

This link provides to see what app you have as connected.

1. Removed many apps and now it looks like this below.

2. Further more there is settings box which shows up like this below:

Simply put - this controls Apps how they use Facebook authentication etc. Just turned it to off for my account. 

This setting should take care how my data is shared by my authentication, but this doesn't answer as to how if one of the friend has provided access to some app - would that mean the App would still have my demographic data ? 

Awaiting to reach out some folks to have an answer on this.
