MTN 3G and GPRS pppd setting on linux (Fedora 4)

[MacNabs]

Hi
I am using a merlin u630 data card and have successfully got it working. Has anybody configured the pppd dialup scripts for MTN 3G/GPRS? I would like the chat AT commands for a GPRS_ONLY , 3G_ONLY and 3G_PREFERRED connections.

Here are my current working chat scripts:

MTN_3G_ONLY.chat
ABORT BUSY
ABORT 'NO CARRIER'
ABORT ERROR
REPORT CONNECT
TIMEOUT 60
"" "AT&F"
OK "ATZ"
OK "ATE1"
OK "ATE0V1&D2&C1S0=0+IFC=2,2"
OK 'AT+CGDCONT=1,"IP","internet"'
OK "AT+CGEQMIN=1,4,64,384,64,384"
OK "AT+CGEQMIN=1,4,64,384,64,384"
OK "ATDT*99***1#"
CONNECT ''
TIMEOUT 60

MTN_3G_ONLY
lock
name MTN_3G_ONLY
connect "/usr/sbin/chat -f /etc/ppp/MTN_3G_ONLY.chat"
/dev/ttyS2
460800

Also what is the diiference between the MTN "internet" and "myMTN" APN's

Thanks

Eh, yes there IS a difference between the two APNs!!!!!
Have you tried roaming internationally not using the INTERNATIONAL standard for APN access - "internet". If you dont use the internet APN, you will not break out locally and will end up coming all the way back to South Africa to break out onto the internet.

I wish MTN would start conforming to International Best Practices. All the other networks do...

Hi Thanks guys for the info.

I still would like to know the AT commands for MTN GPRS / 3G.

With Vodacom its:

OK 'AT+COPS=0,0,"Vodacom-SA",0' (GPRS Only)
OK 'AT+COPS=0,0,"Vodacom-SA",2' (3G Only)
OK 'AT+COPS=0,0,"Vodacom-SA",3' (3G Preferred)

Thanks again

Here are the AT commands if anybody is interested, just changed Vodacom to MTN and it works like a charm.

OK 'AT+COPS=0,0,"MTN-SA",0' (GPRS Only)
OK 'AT+COPS=0,0,"MTN-SA",2' (3G Only)
OK 'AT+COPS=0,0,"MTN-SA",3' (3G Preferred)
