[ UPDATE 19/09/2020 15:00 ]: TM says 200Mbps upload speed for 500Mbps Unifi plan was a mistake. More details here.
Last month, TM had introduced faster Unifi broadband plans with speeds up to 800Mbps. On top of that, you can get the option to add bundles such as Unifi Plus Box and Unifi Mobile with a significant discount.
When the plans were announced, both 800Mbps and 500Mbps plans were listed with 200Mbps upload speed. Turns out, TM has quietly reduced the upload speed of its 500Mbps plan by half.
This change of upload speed was discovered by one of our readers who had subscribed the 500Mbps plan on the 24th of August. Apparently, TM had stated the 200Mbps upload speed by mistake and it should have been 100Mbps.
The TM Unifi 500Mbps fibre broadband plan with 100Mbps upload speed is currently listed at RM249/month without the extra bundles but you do get a free Mesh WiFi Deco M9 Plus worth RM999. As a comparison, Maxis offers 500Mbps with 100Mbps upload speed at RM219/month, and it comes with 2 units of Mesh WiFi.
Thanks Wang Mat for the tip!
