PSM / eDRX support for Sprint network provider with Hologram SIM

Hi
I am using Hologram SIM with my customer board based on Nordic nRF9160 module. I am trying to use the PSM / eDRX feature, but not getting any success …

The following are the AT commands I use for PSM, after powering up my custom board, and sending AT+CFUN=1:

AT+CPSMS=1,"","",“10101010”,“00100001”
OK
AT+CPSMS?
+CPSMS: 1,“10101010”,“00100001”
OK
AT+CEREG?
+CEREG: 5,5,“590C”,“03BE4711”,7,“11100000”,“11100000”
OK
AT%XMONITOR
%XMONITOR: 5,“Sprint”,“Sprint”,“310120”,“590C”,7,25,“03BE4711”,108,8665,24,34,"",“11100000”,“11100000”,“01001001”
OK

In the last response for AT%MONITOR, the “111” indicates that the PSM is deactivated. Has anyone faced similar issue with Sprint provider? How can I set the PSM mode active? Any help will be really appreciated:)

Thanks

Hi

I am actually thinking of trying SIM from other company with which the features PSM / eDRX actuall work. Any suggestion would really help!

Thanks
