The ZTE MF293N is a popular 4G/5G CAT6 router, often bundled with mobile network operators like Vodafone, T-Mobile, Telstra, or Smart. While these "locked" routers offer subsidized hardware, they restrict you to a single carrier’s SIM card. Unlocking your ZTE MF293N allows you to use cheaper local SIMs when traveling, switch to a better provider, or increase the resale value of your device.
