It's extremely hard to tell except to test it yourself, because mobile network may be different for each location.
For my area, Unifi Air has better speed from morning to afternoon, congestion at night rather bad. Whereas Unifi Mobile also has congestion but everything seems to be still running smooth. Hence, I use Unifi Mobile BEBAS currently.
It may be different for your location. So, if you wish to try unifi air, you had better take the SIM only since it does NOT has any contract. But, need to pay RM100 advance payment.

Unifi Mobile Bebas has three (3) unlimited data add on.
1) RM1 for 2 hour.
2) RM3 for 24 hours.
3) RM20 for 7 days.
All comes with unlimited tethering with capped speed at 8mbps, depends on location and congestion.

TM point CS told if your area has unifi mobile coverage, you'll be able to use unifi air too.
I was using unifi air for 2 weeks, on Feb 2020, but terminated due to badly congested at night time.
Unifi Air is using LTE band 5 in my area. It's actually using the same LTE band as unifi mobile.

Double posted.

Unifi Mobile postpaid does NOT have unlimited tethering, it’s unlimited data for phone.

1) SIM only has no contract.
2) SIM with device has 24 months contact.

I took the SIM only for testing and need to pay RM100 advancement, but it turned out very congested at night time.
I would never take the modem, because you still need to return the modem IN WORKING CONDITION after 24 months. It's basically just FREE RENTAL.
My area only has LTE band 5 too. You may try to subscribe unifi air SIM only for testing.

Yes, you can put it in smartphone provided your phone support LTE band 5.
You can cancel it through mobilecare app live chat, but you'll have to wait around 90 days to get the balance of your advance payment according to what CS told me.

FYI, Tenda 4G 680 (RM260+), or D-Link DWA-953 (RM380+) could be used just in case you need a 4G modem.
I used unifi air for around 3 weeks, and I still have RM30 balance after the last bill, but haven't get it back yet.

Your area has LTE band 38 or 40, or both in addition to LTE band 5. So, you'll get 4G+, unless your phone is bugged, JK .

BTW, thanks for sharing RM0/weekly.

Everyone has returned home, it seems Unifi Mobile BEBAS is also getting congested with a rather SLOW speed to 1-4mbps.
Unifi Mobile users are growing rapidly, wonder if it could cope with its network.

Yes, it allows hotspot.
"Internet not usable" is because of too many users, which your area has network congestion.
Just like my area, very slow at around 1-3mbps DL and 3-5mbps UL.
Anything that's FREE, it's perceived as NO GOOD.

P.S. I'm not saying unifi mobile bebas is not good, just that when Unifi Mobile gives out FREE unlimited data, many people will be using it at the promo time. It's in fact quite stable in my area.

Any usage will extend the validity to 90 days. I believe buying alone will NOT do, you'll still need to do some browsing, simply open a few webpages.

It has been said many times. All unlimited data add-ons are capped speed at 8mbps.
DISREGARD what Unifi Mobile CS says, cause they will KEEP TELLING you unlimited data does NOT capped speed.
The expensive data is truly HIGH SPEED data, depends on area.

I'm sorry idk, I haven't used any of its postpaid b4 because it doesn't have unlimited tethering.
For RM99, I had better go for U Mobile GX68.

I said “had better”, I neither use Unifi Mobile POSTPAID nor U Mobile. So, I can’t solve your queries.
I’m using Unifi Mobile PREPAID, its weekly unlimited data also allows unlimited TETHERING, although with capped speed at 8mbps.

From experience, I don't think you may get TnC for that. Just like unifi mobile Bebas, their CS will keep saying its speed is NOT capped.

You need to check the modem has LTE band 5.
Yes, Tenda 4G680 can be used with unifi mobile bebas. You can connect an RJ11 phone to the modem to make phone call. My cousin is using it.
Alternative choice: (1) D-Link DWA-953, (2) Huawei B525s-65a, (3) Huawei B618s-65d

You'll get free 30 days unlimited data for NEW SIM. It's capped speed at 8mbps. The free 3gb 4G data is high speed data, but you'll need to wait till the free 30 days expired.

Sorry, I thought u order Unifi Mobile Bebas (Prepaid).
Postpaid doesn't have speed capping at first according to earlier posting. I'm not sure.

Any usage will extend the validity to 90 days, be it call, SMS, or data like simply open a webpages.
So, your # is now extended to 90 days from the last day usage.

Is that postpaid 99 for RM59? If yes, it has a 12 months contract. How could you port out NEXT month?

If you chose the bottom one, it has only 10gb quota with NO contract.
