Review on 🌐 ZTE MF833V Unlocked 4G LTE USB Modem, LiveU Compatible, Android Head Unit (MTCE Firmware Only) - Please Inquire Before Purchase by Christian Byrd

I need a 4G LTE USB modem that works correctly with Costa Rica's telecom carriers, specifically Kolbi (the largest carrier with the best coverage in the country). It works great and is the best modem I found during my research that meets almost all different frequency specifications for LTE 4G, 3G and GSM 2G not only for Kolbi but also for other providers like Claro. works fine with a USB tethering on the internet when connected to a GL.iNet GL-AR750 AC router (which has an OpenWRT based system).
