Working with GSM modems via AT commands
Because I just got a Huawei K3520 GSM modem and I'm going to play around with it to make it send notifications in case something at work goes down. Here are the AT commands I found useful.
# Entering your pin in case it needs a password. >AT+CPIN="xxxx" <OK
# Finding out your service center number >AT+CSCA? <+CSCA: "+401234567890",145
# Finding out your own number >AT+CNUM +CNUM: "","1234567890",129
#Setting network connection preference ( some might need 2,4 at the end instead of 1,2 ) AT^SYSCFG=2,1,3FFFFFFF,1,2 # for GPRS/EDGE Preferred AT^SYSCFG=2,2,3FFFFFFF,1,2 # for 3G Preferred AT^SYSCFG=13,1,3FFFFFFF,1,2 # for GPRS/EDGE Only AT^SYSCFG=14,2,3FFFFFFF,1,2 # for 3G Only #The ^Mode status lines mean this: ^MODE:3,2 # indicates GPRS ^MODE:3,3 # indicates EDGE ^MODE:5,4 # indicates 3G ^MODE:5,5 # indicates HSDPA
#Setting OWN Number AT+CPBS="ON" AT+CPBW=1,"<number>",,"<name>" AT+CPBR=1 #Showing OWN Number if set AT+CNUM
