You might receive a ZTE MF927U or MF985 (both 4G) at no cost if you commit to a small data plan.
No. Factory reset only clears settings, not hardware.
Technically, you could desolder the 3G modem from the MF65’s PCB and solder a 4G module from a donor device. This requires advanced micro-soldering skills, schematics, and custom firmware. It is not free (tools alone cost $200+) and will likely destroy your device. Avoid.
The ZTE MF65 is fundamentally a 3G HSPA+ device and cannot be "upgraded" to 4G LTE through software or firmware updates. The hardware lacks the necessary internal 4G radio components to support LTE bands.
