Coming from the TP-LINK MR600 (which is a basic 4G router for simple use) and then from the ZTE MC888pro, the difference with the new router is huge. It is much more stable, with a better UI and obviously fewer bugs than the MC888pro.

In terms of speeds, the difference is impressive: from 150-200Mbps download I am now consistently at 400+Mbps down, although the upload remains low at 15Mbps. Even after disabling Mobile Security, I did not see any noticeable change in performance. Certainly, the external antenna plays a big role, as it helps to catch the optimal signal point. For comparison, at the same spot the iPhone 16 Pro Max gets about 100Mbps down and 7-10Mbps up.

A very useful feature is the 10-meter power-over-ethernet cable, which allows you to place the router even on the roof without needing to search for outlets. The T3000 proves to be extremely reliable, as it has not dropped even once, despite supporting over 30 Wi-Fi devices simultaneously.

Negatives
There is no option to change DNS, which is limiting.
The Band Locking has quite a few bugs and often requires a factory reset to work properly.

@JohnXeon Since I am facing an issue with torrents when you mention "For torrent users enable TCP connection only, uTP must be off." are you referring to a setting in ZTE? I searched and did not find anything like that in the menus. If you can answer me, you will save me.

The MC889 is very stable! Contrary to what the friend wrote in the previous review, the modem has no problem no matter how heavy the workload is. The issue is with the cosmote sim when mobile security is activated, under heavy workload it locks the sim and the router freezes. If you go to mycosmote and deactivate mobile security for this connection, the problem will not occur again.

For torrent users, through the application you use to download, activate only TCP connection, uTP must be off.

The Outdoor unit (MC889) sticks or restarts on its own, especially under workload. When it sticks, it does not recover on its own unless I disconnect it from the power first
