Because the MF920V is the last of its kind: a hotspot that is . Newer 5G hotspots often have eSIMs soldered to the motherboard, non-removable batteries, and firmware that checks for unlock codes via a live server (making paid unlocks impossible).

For travelers, remote workers, and budget-conscious users in developing nations, the MF920V remains the gold standard. On a cold Tuesday evening, I unlocked my own ZTE MF920V. I bought it locked to O2 UK for £12 on eBay. I paid $9 to a website in Romania. Six minutes after entering the 16-digit code, the LCD screen flickered. The O2 logo vanished. In its place: "T-Mobile NL" (a Dutch SIM I had lying around). An unlocked unit sells for $60
The device did not cheer. It did not blink. It simply worked.
