Hello, we are currently making an sms application in Uganda using the Airtel and MTN mobile networks. When we run our application via Airtel, it goes smoothly, yet using the MTN networks seems to throw a bunch of errors. We have tried both the RAZR3 and the Huawei E3251, and yet the same errors persist. Based on the logs, it seems to be a memory issue:

GSM1=> Airtel
GSM2=>MTN

CMS ERROR 300:


CMS Error 500


CME Error 25:


CME Error 516:


These are the four different errors we are seeing. I removed the PDU input for now.

Thanks

Here is our smsd.conf as a reference:

Update:

We accessed the phone directly and did the following commands:

AT+CPMS? ("MT","IM","OM","BM","DM"),("OM","DM"),("IM") OK
AT+CREG? +CREG: 0,1 OK

AT+CREG=? +CREG: (0- 1) OK

based on this, we set up our smsd.conf as follows:

##MTN
[GSM2]
##ensure device corresponds to serial port
device = /dev/ttyACM0
pre-init = CREG=1
incoming = yes
check_network = 0
check_memory_method = 31
memory_start = 0
primary_memory = MT
hangup_incoming_call = yes
##mobile phones do not need pins. unsure about modems
#pin = 1111
baudrate = 115200
##state the queue you wish to utilize
queues = mtn

The CME error 300 went away for primary memory, so thats a plus! However we are getting 500 errors still, and the pre-init string did not work. Is there a way we can set CREG=1 from the conf file?
