No wonder la.
Maybe you can buy all SIM from the telcos to try?
Based on your speedtest, Unifi Air speeds seems unstable in your area.

What phone you are using currently?
Well cannot rely on phone so much, there is a possibility that the line there is crowded also.
Or maybe the line for Band 40 also not so strong, so it will affect the speed also.
There is a lot of possibilities here.

Well it is an old phone, cannot expect much to have amazing speeds.
Maybe if you buy a router, maybe can get better speeds overall.
But that is also depends on how strong the Band 40 or 38 coverage are.

For me non peak is around in the 1 am to 4 pm.

I am using it outside of Unifi Air coverage, they have upgraded my area with Band 40 which previously only Band 5 but did not update the map yet.
Around Centrepoint, Seremban.
Got 5 main taman around there.

Shopee got

I buy B818 from Lazada.
SING4G the name of the seller.
So far so good.
B618 is OOS during that time, so I just buy B818.

Wait, since when unifi Air got Band 1?

You can use HManager to lock the band.

If you got any issues with the internet, do PM me ya.
A bit crowded to post in this thread.
I will assist you as much as I can.

LPDA 1 unit is rm75.. need 2 so 75x2 = rm150

the bracket is the same for tv antenna.. around 8-10 ringgit.. the metal pole is around 10-15 ringgit.. all i bought from hardware shop..

no cost of installation as i did all by myself since I have all the tools (power drill etc).. just need chair/staircase to install

if you are not confident to install urself, maybe mytv@freeview installer can setup the pole everything for you..

A new customer (yesterday received the sim) +without device (sim only)

Testing with my phone 2nd sim (Oneplus7T) the speed was around 60MB-71MB

Nice ah.. coverage blue..

Congested?
Already check sinr rsrq value etc?

Well your SINR is quite bad.
Maybe congested.

I got unifi air sim only and was wondering whether it can work with mobile router like TP-Link M7200. Anyone have any experience?
