Hi @kieng_quan_hu_nh ，
These two versions belong to different versions, and the baseline span is relatively large. Are you sure you need to upgrade to a new version?

Currently I am using the modem Quectel EC20CE 16 ports firmware EC20CEFBKR03A05M2G_GW in Vietnam,when I insert the sim card Mobifone into the modem and using the AT+COPS,the response show successfully +COPS:0,0,“Mobifone”,7, then i get the information of the sim card using AT+CUSD=1,“*101#”,15,the response is +CME ERROR:100,but when I use another Quectel EC20 16 ports modem using firmware EC20CEFAGR06A17M4G,everying works perfectly.
So my question is will it work fine if i update the current modem the new firmware.
this is the image of the modem need to update firmware:
