Hi,
Got the Hologram.io developer SIM card, thanks.
I have an A6 GPRS/GSM module which I have used successfully in the past.
I have installed the SIM and communicating with the device through AT commands.
I don’t seem to be able to connect to the network. After I reset I get:
^CINIT: 1, 0, 0
^CINIT: 2, 32, 41891
^CINIT: 8, 2048, 1
^CINIT: 16, 0, 1638410
^CINIT: 32, 0, 0
+CREG: 0
+CIEV: service, 0
+CIEV: roam, 0
+CREG: 2
+CIEV: service, 0
+CIEV: roam, 0
+CREG: 3
which seem to indicate that the device tried to search for carriers but got rejected.
If I issue a “COPS” command I get
AT+COPS=?
+COPS: (3,"Orange","Orange","42501"),(3,"Cellcom","Cellcom","42502")
OK
which seems to indicate that the status is “forbidden”.
The two carriers are all the carriers in Israel that offer a 2G network.
Tried to force a manuall connection but only got:
+CME ERROR:Network not allowed emergency calls only
Any ideas what might be happening? Do I need to enable roaming in some explicit way?
Israel seems to be listed in Hologram’s “Zone 1”.
Perhaps roaming agreements are in place for 3G/4G devices only?
Please advise,
Arik.
