I just subscribe for this plan because maxis has the good coverage in my (non-fibre) area compared to other telcos and provide unlimited(?) data to use. After hearing it throttle to 512kbps, I had no choice but to limit my usage down since I can't afford to get throttle during gaming session.

While 512kbps is still better than celcom which drop to 64kbps, they could've just limit the usage to 2mbps at least. What can we do with 512kbps anyway, this is not dial-up era anymore

Is Twitch and Discord are affected too by any chance?

I can still access speedtest here. Probably there's an issue with routing. Reset your modem should work

For SIM only, you can just go to the store/booth and pay upfront to get the sim card, activation in 5minutes iirc
For SIM + Modem, same as above but some store may not have the modem ready for you. Do call their respective maxis store beforehand

Seriously, I don't mind if Maxis capping Youtube streaming to 2mbps but also capping everything else in 8pm~12pm is just a stupid move from this carrier. As if the 300GB FUP limit isn't enough but I didn't even hit that cap for months since I use this plan, should just move to Unifi Air if I kept getting this kind of treatment

Wow with that kind of speed on normal hours alone is already a red flag, mind you the upload speed is almost on par with what unifi air gives.
2mbps limit for 8-12pm is seriously unacceptable, even for single user since this prime time that people consume their content online, limiting this for everything hurts a lot, even for gaming. Complaining to mcmc soon

So far, I can stream youtube and other video on 1440p during 8pm~12pm this month, no throttling observed on other site too but network would suddenly halt (around 12.30am~3am) and needed to reset router when it happened.
