A few years ago, the ZTE MF920U was everywhere — in offices, apartments, and backpacks of frequent travelers. It was a simple and reliable pocket-sized 4G router that let you connect multiple devices to the internet at once.
Now it’s much harder to find. Even if you do come across one for sale, it’s usually leftover stock or refurbished units with only a minimal warranty. Instead of the usual 12 months from the manufacturer, stores now offer just 1–3 months.
Why the MF920U Has Become Rare
The reason is simple: production has been discontinued. Newer models have replaced it, offering updated components, better batteries, and support for current standards.
With older batches, there are several risks:
-
Batteries have lost capacity after years in storage
-
No firmware updates or security patches
-
Higher chance of getting a refurbished unit
-
Short warranty periods that don’t give peace of mind
In short — buying one now is a gamble.
What the ZTE MF920U Offered
At its peak, it was a solid 4G option:
-
Up to 150 Mbps download speeds
-
2.4 GHz Wi-Fi for up to 10 devices
-
Compact size with around 6–7 hours battery life
-
Some versions included ports for external antennas
But technology moves on, and even in perfect condition, this model no longer looks like the best choice today.
OLAX MT80 — The Modern Alternative
Among current pocket routers, many users are switching to the OLAX MT80. It keeps the main strengths of the MF920U but adds important upgrades:
-
Supports all LTE bands needed for Ukrainian mobile networks
-
3000 mAh battery for longer runtime
-
Modern Type-C charging port
-
Two CRC9 connectors for external MIMO antennas
-
Official seller warranty

Why the MT80 Makes More Sense
If you’re in a weak-signal area, the ability to connect an external antenna makes a big difference. If you travel often, a larger battery and a modern charging port are simply more convenient. Most importantly, buying a new device with an official warranty means you won’t be left stranded if something goes wrong.
Where to Buy
On 5G.IN.UA, the OLAX MT80 is available both as a standalone router and in bundles with external antennas to boost signal — a ready-to-use solution for home, office, or travel to areas with poor coverage.

Bottom line
The ZTE MF920U was a good choice in its day, but buying it now without official warranty coverage is risky. The OLAX MT80 offers the same speed class but with a fresh battery, modern Type-C charging, full frequency band support, and external antenna capability. In 2025, it’s the safer and more practical choice.
