COPS=? command to show all networks | Telit Cinterion IoT Developer Community
September 23, 2016 - 9:20pm, 9204 views
I am using PXS8 and am trying to view all the networks that the modem can see.
When I enter the AT+COPS=? It returns only AT&T networks. I am confident there are other networks (T-MOBILE, Verizon) that it should be reporting.
Is there a AT command that I am missing so I can see all the networks even if the Operator is forbidden?
AT+COPS=?
+COPS: (2,"AT&T","","310410",2),(1,"AT&T","","310410",0),(1,"AT&T","","310260",0),,(0,1,2,3,4),(0,1,2,90,91)

Hello,
First of all I can see this line:
^SCFG: "MEopMode/AccT","GSM/UMTS"
where GSM/UMTS access technology is set. The other options are cdma2000 and MULTIMODE for both. Please also note that in AT&T specific USIM Elementary File there is RAT mode parameter which cannot be changed by this command.
Please try to change to MULTIMODE.

Hello,
I have changed the MEopMode/AccT setting to "MULTIMODE" and restarted the module. This change has no effect when searching for available networks.
Still when the AT+COPS=? is given the response is
+COPS: (2,"AT&T","","310410",2),(1,"AT&T","","310410",0),(1,"AT&T","","310260",0),,(0,1,2,3,4),(0,1,2,90,91)
The SIM is an AT&T sim, but I would expect to see other networks such as (T-Mobile and Verizon). Is there any other AT command settings that would allow the module to see other networks besides AT&T?
Hello,
You have already all the possible bands set.
Can you check with the SIM card from other operator? Another thing you could try is setting cdma2000 and then check. You can also try to disable the SIM interface with AT^SCFG="SIM/IfAvl","off". There's another command for network scan that you could try: AT^SNMON="INS",2. Please also check AT commands specification for more options. Please deregister form the network with AT+COPS=2 before.

Hello,
Does the fact that I have an AT&T sim card installed prevent the PXS8 modem from finding other networks?
Thanks
It could be possible. But I can't test it in Europe. That's why I advised you to try with other operator's SIM card. Please also check AT+CPLS? and AT+CPOL? replies.
