True, they've already been banned by telcos for their mobile plans meant for phones.

Actually, the ban already imposed quite some time  since you cannot use prepaid/postpaid mobile plans such as Yes Power 35 and Telco U mobile plans on them.
Try placing a Yes prepaid/postpaid mobile plan SIM(not the broadband SIM) into these modems, they won't boot up or connect with no signal.
Only their data only broadband plans can be used because the telco allows buy your own(BYO) modem plans with no contracts.

Zyxel is very popular brand in Europe due to their anti-China policies. It is among the popular benchmark models used by Ericsson which is DNB's vendor.

The screenshot you posted is from non official Yes channel. Also there're 2 models out there one being the 3 Three model mostly already sold out everywhere and the restricted EE model which don't allow lockband function. Their IMEI cannot be changed and ISPs view them as safe models that cannot bypass mobile plans meant for phones. The EE model is useless because of its firmware limitations, and the official Zyxel branded ones expect to pay close to US$500 a new unit.

If you mentioned about blocking, those models with QWRT(China modded OpenWRT) out there will be the ones to be blocked first high on their lists. They allow illegal IMEI modifications and bypass of mobile plans without hotspot quotas.

Many of those modded brands out there claimed to be OpenWRT based are actually China modded QWRT based not the official channel. No one actually knows they have hidden backdoors in them and usually the tactics used by China modem suppliers is that they won't upgrade their QRT firmwares frequently for specific models to push newer models with newer versions of the firmware so you will have to keep buying from them.

based on history. mcmc close one eye for imei mod modem
wifi interference  is a big NO NO
seem like Zyxel NR5103E wifi out-of-spec

there are another  case wifi 2.4G device interference with P1 2.3G spectrum. dont find the link

detailed and well informed explanation from you as always man, u must be an expert in this field

yes the screenshot is from one of the unofficial yes 5g fb group posted by a random anonymous user which caught my attention

btw given tht ISP view Three & EE model as safe models as their imei cannot be changed, i wonder whether these models might still face the risk of being banned outright even if used with a broadband plan (if mcmc were to decide so), this is particularly concerning

considering these models has no SIRIM and seems to be out of spec as what JLA claims

I told you lo is Yeacomm the light design is exactly the same.

Not trying to backup YES or what not, but with 5G, it really boils down to several factors such as location, signal strength, type of modem router used. All telcos in MY under DNB are on the same radio bands, so if a tower is close by to your house, you should get a good enuff speed .... My ss as proof ...

Also would like to clarify that the 3 Three and EE UK Zyxel NR5103E modems are actually Mediatek T750 based not Snapdragon X55 based as many had claimed by online sellers.

Among the other models which uses this Mediatek T750 chipset are:
Yeacomm NR330 5G Modem AX3600 WiFi-6 Router
Arcadyan Meteor aka Telstra 5G Internet Modem 2 (Gen 2)

The Snapdragon X55 chipset based modems are:
Telstra AW1000 5G Home Modem (Gen 1)
TP-Link Deco X50-5G 5G AX3000 Whole Home Mesh WiFi 6 Gateway
Zyxel NR5101 5G NR Indoor Modem

The Mediatek T750(Sept 2020) is a newer chipset compared to the Snapdragon X55(Feb2019) by one year.
It has supports CA across wider 5G NR bands compared to the older Snapdragon X55

are you at ground floor level ?

does YES cap the bandwidth ?

Apartment building, 3rd floor. No speed cap, unlimited data (as long as you're connected to 5G). 4G usage will have a data cap of 100GB, after which when quota is finished, will capped your 4G speeds to 1MBps if not mistaken. Best to use a router that can lock band so that it doesn't drop to 4G on its own.

What bands did you lock ? N78 and B28 ?

I think I did one too many speed tests with my prepaid. 3 weeks ago wasn't that low, now it looks like I am being capped.

Update
-----------
Solved the problem, Possibly the connection drop to 4G more than usual recently so I removed one of the cheap rabbit ears antenna (the 4G one) from the modem, leaving just the 5G antenna. Seem to stabilise the 5G signal reception and stay at 5G. Maybe the 4G antenna was interfering with the 5G one.

does the original yes 5g wireless broadband able to lock band ?

is there any frequent disconnection?

how much max bandwidth do you ever use a month?

Hi, got anyone using Yes flexi? If put the sim card into 5G mifi, able to use?

Since this is broadband plan, it should work if it support B28 and N78.

okay thanks. coz just now i went through some comments in the group, some mentioning that certain devices will block the plan.
Therefore wanna confirm with existing users before deciding wanna apply or not

anyone still using this YES 5g plan?

Signed up for the free 30 days trial using esim on my phone. Only able to detect 4G speeds during speed test even though the coverage check showing there is 5g coverage in my area.

Planning to get  Zyxel NR5103E modem to use with the SIM. Would it be better at pulling 5G connection?

And if the connection is bad. Is it difficult to cancel the subscription? I heard have to go physically to Yes centre in KL.
