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.
Firmware vs. Hardware: While firmware updates can fix bugs or unlock a device to work with other carriers, they cannot add new radio frequency bands. A 3G device will always be a 3G device. zte mf65 upgrade to 4g free

3. The Low-Cost Replacement (Under $20): Instead of investing time in a hopeless hack, purchase a used, entry-level 4G MiFi device. Models like the ZTE MF65M, ZTE MF283, or Alcatel LinkZone are widely available on eBay, Facebook Marketplace, or thrift stores for $10–$20. This is the financial equivalent of "free" compared to the value of your time. The MF65M, in particular, is a direct successor to the MF65, using the same form factor and battery but with a proper 4G LTE Category 4 modem.
