Hello,
I have a sim7000A that I’m using with a hologram sim. I can see the device in my dashboard as connected to the global network, but I am unable to make a connection to the internet. I’m executing AT commands via PuTTY, here is the output:
AT
OK
AT+CFUN=1
OK
AT+CNMP=38
OK
AT+CMNB=1
OK
AT+CIPSTATUS
OK
STATE: IP INITIAL
AT+CSTT=“hologram”
OK
AT+CSQ
+CSQ: 25,99
OK
AT+COPS?
+COPS: 0,0,“T-Mobile Hologram”,7
OK
AT+CPSI?
+CPSI: LTE CAT-M1,Online,310-260,0x7BDE,15751179,372,EUTRAN-BAND2,750,3,3,-15,-95,-65,11
OK
AT+CIICR
+PDP: DEACT
ERROR
It looks like I have good signal strength and am online, but when I send AT+CIICR the device hangs for about 10 seconds and then responds with +PDP: DEACT ERROR. This is my first time using a cellular modem and I’m not sure if I’m doing something wrong, or if the issue is somewhere else.
Its possible that my PDP context is set incorrectly. I ran the following:
OK
AT+CGDCONT?
+CGDCONT: 1,“IPV4V6”,“broadband”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0
+CGDCONT: 13,“IP”,“hologram”,“0.0.0.0”,0,0,0,0
+CGDCONT: 2,“IPV4V6”,“ims”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0
+CGDCONT: 3,“IPV4V6”,“sos”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,1
OK
AT+CGACT?
+CGACT: 1,1
+CGACT: 13,0
+CGACT: 2,0
+CGACT: 3,0
OK
AT+CGDCONT=13,“IP”,“hologram”
OK
AT+CGACT?
+CGACT: 1,1
+CGACT: 13,0
+CGACT: 2,0
+CGACT: 3,0
I believe that AT+CGDCONT? indicates that hologram is number 13, and that AT+CGACT? indicates that 1 (broadband), not 13 (hologram) is active. I tried to use AT+CGDCONT=13,“IP”,“hologram” to set hologram to the active PDP context, but it doesn’t seem to have done anything as AT+CGACT? still reports that 1 is active. I’m not sure if this is an issue, but it seems incorrect to me.
Any help would be much appreciated!
