EC2X network information commands

What is the difference between the commands AT+CREG and AT+QNWINFO access technology ?
QNWINFO Looks more detailed ? Or its about the data ? while CREG is generic ?

AT+CREG //Network Registration Status

AT+QNWINFO //Query Network Information

Thanks and sorry, i dont understand.
Whats the difference between CREG Act (“Access technology selected”) and QNWINFO Act (“The access technology selected”) ?


Ok thanks for the explaination !
I’d say that qnwinfo is more about the data service.
creg is the generic access technology.
