1) Are you testing it on the same phone on same SIM slot?
2) Is your phone a dual SIM 4G+ supported?
3) How much is the usage for each SIM?

For my previous experience, they both are getting around the same speed at my location.

No, the ZTE from Maxis is a 4G only router.

After consumed 300GB, the speed would be throttled to 20~30mbps. So, your location may have network congestion. And, YouTube is getting throttled at night time from 8pm~12pm at 1.5mbps whether or not you have reached 300GB.

Many users of this Go WiFi plan already confirmed all video streaming sites would get throttled to 512kbps once reaches 300GB usage. So, this plan is definitely not suitable for users who loves to watch TV.

Yes, you can just walk into the Maxis store and sign up immediately walk away with the SIM only with no contract.
You may need to wait for the ZTE 4G router if that particular store has no stock, and remember, taking the 4G router will bind you into 24 months contact.

If you take the 4G router provided by Maxis, it'll have a 12-months contract.
SIM only is free of contract.

The ZTE router by Maxis is a 4G only router, and 30-40mbps may be its max speed. Huawei B818 is a 4G+ router, plus its signal reception is said to be very powerful. Therefore, of course you’ll get high speed with Huawei B818.
Yes, this plan would throttled video streaming sites at night time from 8pm-12am. And, throttled for all day after 300GB usage. Still, the browsing and downloading were throttled at 20mbps which was acceptable to me. You may try complaining to MCMC and see if it’s gonna changed, good luck.

I used this plan two months back as home internet, terminated it because my home finally has Unifi fiber internet in OCTOBER 2020. Luckily, I did not take the router, otherwise I’ll have to use it until May 2021.

As my previous usage, all video streaming sites, google play store updating/downloading, FaceBook are getting badly throttled to 512kbps, while speedtest, downloading sites (e.g. filehippo), Steam games updating/downloading are throttled to 20~30mbps.

Anyways, sorry to hear that and that's very bad of Maxis. Probably, Maxis has amended this MaxisONE Go WiFi again since the TnC stated.

6.4 - Maxis reserves the right to modify for any reason whatsoever or suspend or terminate (temporarily or permanently) the Services at any time and from time to time with or without notice. You agree that Maxis shall not be liable to you or to any other party for such modification, suspension or termination of the Services.

You should have got a 4G+ router instead if your location supports 4G+ network. TP Link MR6400 is a 4G only router, and so ±30mbps might be the max speed you could get using that router.
Do take note that this MaxisONE Go WiFi is not truly unlimited high speed internet, it has a quota of 300GB high speed and after that it's throttled to ±20mbps. Furthermore, all video streaming sites will be badly throttled.

Have you tried DiGi infinite 150 although it is a bit pricier or a cheaper alternative Unifi Air which is at your location? Since you’re not under contract, you may try them if you haven’t.

Your upload speed is +19mbps. It's more like congestion than throttled.

You may also complain to MCMC on Unifi Air poor coverage. Since Unifi is an GLC, I believe it may get approval for erecting tower or enhancing network faster and easier than non-GLC ones.
Otherwise, terminate it and just make do with whatever is good for you.

How much have you used for this month? and How much GB do you use usually for a month?

Yes, I really don’t like that Maxis stated “unlimited even if you’re not in fibre coverage area” on its webpage.
BTW, have you tried DiGi infinite 150 which gives 1000GB quota?

Only 2 , Please update yourself, this DiGi i150 unlimited data plan came up for quite some time before Maxis and Unifi.
Yes, that’s a postpaid plan with unlimited data + unlimited tethering, which means you can use on a 4G router as a home broadband provided that your location has a good connection. It’s an alternative for Unifi Air unlimited data, plus you get unlimited calls if the 4G router can connect a phone using RJ-11 cable.

No, you can use the SIM in any 4G supported devices, eg. Phone, router, MiFi, etc.
You could take the SIM only, and it doesn't have contract.
12 months contract applied if you take the 4G router for RM1.

You should take the SIM only to test your location cause the 4G router from Maxis is not good.

In comparison? Which means you tried both SIMs in the same ZTE router?
For what I meant no good is that it’s a 4G only router. So, if one’s location supports 4G+, they may not get the full speed at their location using the ZTE router by Maxis.

Please read carefully "Add on (optional): RM1 with 12-month contract" below the "buy now". Only if you take the 4G router from Maxis for RM1, you'll be tied to a 12-month contract. I don't see any "forcing" like you said.
This plan is RM138: NP. There's an RM30 rebate for 12-month (no contract) = RM108 if you're a Maxis postpaid user. Anyway, you may just visit any Maxis center and walk away with the SIM only free-of-contract.

BTW, I was using this plan previously. Already terminated it due to changing to Unifi Fiber finally got coverage at my location.

Which router do you use? Some routers are 4G only capable, which may limit the speed to 30+mbps.
Which phone do you use? Most of the phones nowadays are 4G+ capable, that’s why you may reach 100+mbps on 4G+ network.
So, there’s a high chance of getting better speed with a good router, e.g. Huawei B618 or B818.
Note: for congestion issues, regardless of whatever router you use, it’ll be the same. And, also there’s the throttling issue as some people said here, plus the 300gb high speed quotas.
