BG96 AT+COPS command to force connection to network

IoT Modules LPWA Module

Hi,

I’m trying to force a connection to verizon network on a BG96 modem for testing:

AT+COPS=?
+COPS: (3,"Verizon Wireless","VZW","311480",8),(3,"313 100","313 100","313100",8),(1,"AT&T","AT&T","310410",8),(1,"T-Mobile","T-Mobile","310260",0),,(0,1,2,3,4),(0,1,2)

What is the AT+COPS= command to force connection to Verizon in above list?

I’ve tried several variations with no success:

AT+COPS=1,0,"Verizon"
+CME ERROR: 30
AT+COPS=1,0,"AT&T"
+CME ERROR: 30

AT+COPS=1,2,"311480",8
+CME ERROR: 30
AT+COPS=1,2,"310410",8
+CME ERROR: 30

another way , you can lock verizon band and force register
with cmd like this : AT+QCFG=“BAND”,0,8,8 // Lock to B4（catm & nb）
