I can’t get a data connection if I try with a SIM card, which is roaming. If I try SIM cards which register in home networks, all is OK. Roaming SIM cards works aslo well in HiloNC modules, but don’t work witch Hilo3g module.
I’ve no idea where to search, maybe there is a locking mechanism in the Hilo3g module? But it takes some time after, the NO CARRIER +KUDP_NOTIF: 1,5 message appears, there should be some timeout.
What’s the newest firmware version of the Hilo3g modules?
my module states:
AT+CREG? +CREG: 0,5 OK AT+CGREG?<\r><\r><\n>+CGREG: 0,5 OK AT+KCNXCFG=0,"GPRS","*****","****","*****" OK at+ktcpcfg=0,0,"www.google.com",80 +KTCPCFG: OK at+ktcpcnx=1 NO CARRIER +KUDP_NOTIF: 1,5 at+ceer +CEER: User Aauthentication failed OK
