How to identify the currently used network band in quectel modems using AT commands.
Specifically EG21 module or similar LTE modems - Quectel_EC2x&EG9x&EG2x-G&EM05_Series
Need to know which band of network am I currently registered to. Like 2G,3G,4G .
Is there a sequence to use… Mean to ask that if these command should be used after AT,AT+CPIN?,AT+CREG?,etc
Please let me know if there is any sequence of sending commands before sending AT+QENG=“servingcell”
