It's just about better speeds. Depending on the configuration that snapdragon 845 chipset can get speeds in the Gigabit range theoretically. In a real world scenarios we should get over 100mbps easily.

In general 4CA would give out double the speed of 2CA if the same kind of config is used.
These speeds are important to me as someone who uses my phone as a hotspot for my pc at times and I am not covered by fibre in my area so LTE is all I have. Hence I need utmost performance from my devices in terms of LTE speed.
Still, I have a 50mbps fibre line and don't personally need faster. I already stream 3 android boxes and do some downloading with capacity to spare. As an example of usage, streaming dstv now @1080p only takes around 5-8 mbps, netflix at UHD takes around 20 - 25mbps at most.

If you are rooted you may check which bands are being aggregated with network signal guru app and mimo info as well.

Mtn is probably just about the only carrier in SA that enjoys decent CA with the Mi 8.
Their bands seem to be covered.

MTN and Vodacom is running some very interesting aggregation configurations.

MTN runs a nation wide 3CA configuration. B1+B3+B8. Band 3 is always 10MHz. Band 8 is always 5MHz and Band 1 varies between 10 and 15MHz. 15MHz in areas that feature more 4G than 3G devices.

Vodacom runs a B1+B3 configuration nation wide. They then add Band 8 to the mix in certain areas. Band 1 (10-15MHz) + Band 3 (10MHz) and Band 8 (5-10MHz)

Telkom the master of the LTE bands and configurations but as we know the ONLY operator in SA that can actually run 4 carrier aggregation and top all speed charts but choose not too. They run 2 sets of 2 carrier aggregations.
Band 40 (20MHz) + Band 40 (20MHz) they also run a Band 1 (5MHz) + Band 3 (10MHz) aggregation. A real opportunity to aggregate 4 Bands maybe we shall see it someday. Also Telkom does not own ANY low frequency spectrum like Band 8. This means that 2G is run on 1800MHz and that is the reason Telkom 2G coverage is poor and basically the exact same coverage as Band 3 - 1800MHz.

MTN and Vodacom runs their 2G on 900MHz, 3G on 900MHz and 2100MHz and LTE on 2100MHz, 1800MHz and 900MHz.
Cellc runs their 2G on 900MHz, 3G on 900MHz and 2100MHz and LTE on 2100MHz and 1800MHz
Telkom runs their 2G on 1800MHz, 3G on 2100MHz and LTE on 1800MHz, 2100MHz and 2300MHz(x2)
Rain runs their LTE on 1800Mhz and 2600MHz, 5G on 3600MHz

This is some good info.

How is MTN achieving 150MHz? Are they now doing some LTE-U now?
I think I will get some sim cards and see what I get from my tower after this Corona has hopeful settled down.
I need to test out MTN and Vodacom CA and see what I pick up

Oops sorry typo. 15MHz max. They don't have that much spectrum.

My Mi Max 3 received the Android 10 update last night. Update seems to have gone smoothly.

Mia Africa is good too. A bit more expensive than getting it from Gearbest and a bit limited.
Yeah I also buy a lot of my stuff from gearbest. Usually I use their expedited shipping option and it is still much cheaper than buying local. Sometimes I buy local when stuff is on special and the price is more or less the same because for warranty / returns it makes more sense.

I just commented about mia africa cause the abovementioned screenshot was from their website, not gearbest

My original screenshot was from Gearbest. But yes rather order locally.
