Carrier Aggregation on Airtel on Redmi K20 Pro

Basically out of 22 Circles 13 Circles have 40-40 CA and 9 Circles Have only Single B40, 9 Circles they may have CA its like 50-50, While in the other 13 Circles they have CA for 2x2 Mimo, While Devices with 4x4 doesn't get any CA or Maybe very limited, So if a user with 4x4 Mimo supported device like the flagships Mostly don't get CA on Airtel while some people have reported CA working in 1/10 places with flagship phones.

@Luifer who told you in most places they disabled CA.In most states where 30mhz b40 spectrum is there Ca is working on 40+40.

Well sorry for not being clear. What I meant was I was not getting ca here in kerala for the past few months. ,most of the places . Earlier I used to get b3+b40 in my residence but now they have completely disabled it . Nowhere I got ca with airtel
 
So guys, any update on the situation wrt CA. I am getting CA in Airtel in Mumbai but it's very weak and keeps switching. So I got these speeds which is kinda ok because I don't know how much should I expect. But yes, definitely better than 0.87mbps without ca.

I don't know, but when I ran the test on fast.com it gave speeds around 9-10 Mbps with decent pings. It could also be that the tower is far from my home since I get only 2-3 bars.
Edit: Now on 4g,. I get around 230 kbps. Seems I should stop speed testing.

i just want to say one thing even if 4G+ CA is there if its not optimized properly it will perform poorly than single band and if congestion is very high CA will perform little worse (if both aggregated bands are similarly highly congested for ex 3+40 3 maybe given 1 mbps and 40 maybe giving 3 mbps so you will think ok it should give 4mbps but instead it may give 3mbps that can be due to congestion or poor optimization) it all depends on the vendor optimization how well its optimized
 
Yup, I agree. Congestion or non optimisation could be an issue as seen in this result. Relatively early morning and I got good speeds.

I have had similar issues last week with Airtel 4g. Ran a speedtest after your comment, found out it is working. Could be some issue, my net was pretty much patchy till yesterday from last week.
