tIt's me again, the poor guy that lives in a shithole area with monopolize telco.
Long story short, I signed up for Unifi Air without contract during May to test the speed out in my area, as the website showed that I am not covered for their Unifi Air signal.
I found out that my area is available for Band 40, although quite weak (min 10 mbs max 38 mbps) but still better than my original.
Then I went to TM Point to register for contract, but they said no B618 modem available, need to queue.
I agreed for queue and wait for their call.
After 3 weeks, I received the call today and guess what?

They changed their plan to ZTE modem.

I was like seriously?
B618 is worth at least RM 750 - 800, whereas this ZTE shit???
And the performance is lousy AF as shown by previous users (See post above).
Even their staff told me that the performance is a big gap between this 2 models.
They told me to consider wisely if I want to sign their contract again.

I am receiving weak signal even using B618, if I use ZTE I can confirm it will be worse.
And now I am left with 2 options.
1. Cancel my Unifi Air SIM plan as it is not in contract, and back to the Maxis One Go slow speed.
2. Buy a B618/B818 myself and pay RM 800.

I waited 3 weeks just to get this.
This is so ridiculous. And I feel rugi if I were to buy that B618 myself.
I really hope TM can resume back the B618 modem.
I am thinking of ending that unifi air sim plan.
That's all folks.
Sorry for my ranting post.
Poor guy living in shithole signing out.

I got my Huawei b818 and I tested it from 730pm to 8pm

Speed around 10mbps to 20mbps. Sometimes suddenly dip to 2.

Is this normal speed for that time?

Will test the off peak speed on Saturday.

Also, my router already shows it is at 3 bars, is there any chance that getting an external antenna would help with the speed?

Hahaha.
Do not thank me only, thank the other forummers who also suggest me to get this Huawei model.
I cannot remember his name but thanks to him, now finally I can upgrade my speed from the shitty 4 Mbps Streamyx to this awesome 50 Mbps+ speed internet.
Anyway for DNS, you are able to change it directly in the router by inserting some commands in the console of the browser.

But for the B818 code, you replace it with this:
$('#dhcp_dns').show();

What...seriously!?

was thinking on signing up unifi air , but heard they now use ZTE modem , is it any good?

yes, u are right. contact them via live chat for unifi air (a.k.a unifi mobile / formerly webe) will only give you straight answer about the penalty need to be paid. est rm 1500+ 

already ctc them by twitter so they escalate and open a report. now awaiting their decision. i believe their twitter is handled by the correct department ™ not unifi mobile/air team.

ill need to return the modem ofc. and live my life with my longly dreamed fibre internet
well.. im aware of that 24 mnths contract, but the cs at tm point and tm staff that called me did said, once fibre is available, we can switch and terminate. cos it considered an upgrade. 

hope they will ease the process for me. otherwise skmm is the only way to go if unsolved. 

Hi guys, does the ZTE MF286C modem bundled with the plan is a CAT6 modem that can support LTE-A/4G+?
