9160 network selection

hi support team,

how to select network manually, using “8.1 PLMN selection +COPS”   or "8.16 Mobile network operator %XOPCONF", which command should customer use, and what's the difference?

for end customer in America searched network and find Verizon, but when using AT+COPS=1,2,"311480", 9160 can't attach to Verizon., if my understanding is correct.

for "8.16 Mobile network operator %XOPCONF", i think it is the same function.
