Carrier Aggregation on Airtel 4G LTE

But as there is no Fiber Backhaul I think speeds won't increase that much even using 2x2 with 10Mhz.

Maybe, but we can see a good difference just we need to wait and watch. I get band 3+1 CA speeds are 30Mbps in it.

Speeds are only 15Mbps in band 1 5Mhz SISO, we can get 30Mbps with 2x2 MIMO with addition of another 5Mhz we can get upto 60Mbps.

It's 2x2 Mimo here coz Samsung Exynos models shows TBD Mode 2 and CA supports in all Bands except for one Combinations 1+40+40

Then perform a speed test by locking your phone to band 1. If it is more than 20Mbps then your area has 2x2 MIMO.

I'm getting 18Mbps on Single band 1 and it doesn't goes above 18Mbps becoz I have Airtel postpaid and it doesn't goes more that 18Mbps. I can't lock bands of samsung bcoz it isn't rooted it just latches to 3CA directly.

This was on band 1 10mhz 1x1 siso

I think we can lock bands in engineering mode or service mode.

It is 10Mhz that's Why you are getting 20Mbps if it was 2x2 Mimo you would get Max speeds of 75Mbps which Vodafone gives here in Chennai

I read somewhere that Samsung phones service mode can be accessed only with root

No when i bought S8 in 2017 i was able to lock bands by accessing *#2683662# and i was able to even disable 4x4 mimo,cA combinations and as well as was able to lock bands.but in july 2017 update samsung blocked that code.and now it shows not supported and In s9 and latest series it was disabled from begining.

WoW! What were the speeds ? I hope single band be easily able to give speeds of more than 100Mbps.
