I have both the LM321 and CPE 903 models. Here is my experience with both models. The CPE-903 has micro-usb port to power it and hence it is portable, and you can power it with a power bank when/where there is no electric power. It does not require frequent restarting like some routers as it gives a stable internet connection. It has only one LAN/WAN port and you can plug ethernet cable to a computer or into another router. Many people have a problem with sim-tray and it fails to recognize sim card specially after replacing sim card. Mine also failed in the same way. Otherwise it is an excellent device. The LM321 gives me full bar signal and the CPE-903 gives me one bar minus. The CPE 903 seems to have better WIFI range. Using ethernet cable connected to computer, the LM321 gives better internet speed. I did not encounter sim card absent error with the LM321 model. It does not have micro-usb port and it is powered using 12V adapter. Sometimes it fails to give IP
