Hi, I have a EC25 modem and I do not plug the SIM card.
When I want to set a different technology (2G, 3G, 4G) or different operator (MNC) using the following commands, “servingcell” is still the previous one.
AT+QENG="servingcell"
+QENG: "servingcell","LIMSRV","WCDMA",432,35,5962,9C58AFF,2993,453,1,-57,-11,-,-,-,-,-
OK
AT+COPS=1,2,"43235",0
OK
AT+QENG="servingcell"
+QENG: "servingcell","LIMSRV","WCDMA",432,35,5962,9C58AFF,2993,453,1,-57,-5,-,-,-,-,-
OK
AT+COPS=1,2,"43211",2
OK
AT+QENG="servingcell"
+QENG: "servingcell","LIMSRV","WCDMA",432,35,5962,9C58AFF,2993,453,1,-60,-6,-,-,-,-,-
OK
I have 2 questions:
1- How can I apply the above locking on the modem? Is there a memory or similar concept which the current serving cell information is stored and I have to reset or clear before/after locking on the MNC or technology? Is there a complementary command to satisfy the locking conditions?
2- I know that in AT+QCOPS command, I can set scan technology in the first argument (1:2G, 2:3G, …, 7:2G+3G+4G). Now, does the result of AT+QCOPS=7,1,1,2 change after locking on a MNC or a technology (i.e. after solving question 1) or also a band on the modem? In the other words, if I lock on band 8, the result of AT+QCOPS=7,1,1,2 is in band 8 or not?
