View source for Working with GSM modems via AT commands

==WHY==

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.

==WHAT==

Finding out your own number:

<source lang="bash">
# Entering your pin in case it needs a password.
>AT+CPIN="xxxx"
<OK
</source>

<source lang="bash">
# Finding out your service center number
>AT+CSCA?
<+CSCA: "+401234567890",145
</source>

<source lang="bash">
# Finding out your own number
>AT+CNUM
+CNUM: "","1234567890",129
</source>
