I see, that makes perfect sense.

If your phone not rooted cant lock band. If rooted can download network signal tools in play store and disable any band that you want. Unifi Air uses band 38 and 40. But unifi mobile uses band 5 (850Mhz) band 38 (2600Mhz) band 40 (2300Mhz). If you put in sim card to your phone chances are ur phone will see band 5 signal is stronger because 850Mhz can penetrate further and deeper than higher frequency like 2300 and 2600. Our smartphone is really a dumbphone cause they only measure signal strength but not the speed that it has. Usually band 5 is congested and speed is less than 5mbps for my case. So thats why i disable band 5 on my phone.
As for samsung phone there is hidden menu accessible by ussd codes that can let you disable any unwanted LTE band. I forgot what the code is, google away.

Bro, sorry to disturb again. Bought the sim, popped into my phone, it does show full 4g bars, but not internet at all. not even loading. I tried my brothers samsung A8 2016, but cannot fins a working method to do band selection, it also not working at all.
Any suggestion from you?
As from TM, i don't want to say anything abt their support.

Unifi air is more better since can bring back to hometown during holiday + up to 64 user w/o quota

Set apn to unifi
think that full bar most likely is band 5 haha signal strong but speed so so

The ussd codes for samsung to change radio function i think is *#2263# if im not mistaken. Tried in my fren s10 it works last time. But not sure about the codes. It was long ago.

Or

Just buy modded modem from shopee. Personally using huawei b310 now. So far ok la. My place can get 10-15mbps on band 38

huawei b310 modded can lock band to 38/40?

most mifi/modem router default use band 5 which usually congested and slow

I have a similar problem, i was thinking to do long range wireless bridge however i have to erect two towers 40m which is quite expensive. Now im thinling about using this booster for unifi air.

Here i need some opinions about doing this:

If im not mistaken, unifi air is working as the concept with mobile signal? No? If it yes, then i can proceed to buy booster antenna, position it direstly to the tower and connect to unifi air.

Is it possible to do this?

unifi air map. your place under unifi mobile. try with unifi bebas first. use phone which can lock band 40 like samsung and mediatek soc.

booster is illegal. one day mcmc will come visit your home.

If using 4g router and plug in unifi mobile sim card, it will utilize data quota or hotspot pass quota? TM can detect data sharing usung 4g router?
