title: Mobile phone - configuration via SMS
body: <p>In Germany, mobile carriers often provide a simple way to configure your mobile phone for MMS and GPRS: After keying in your phone number and device model on the carrier's website, you get a "configuration sms" sent to you.</p>
  
  <p>I'm trying to understand how that works from a technical standpoint. I have scanned through 3GPP TS 03.40 (<a href="http://www.3gpp.org/ftp/Specs/html-info/0340.htm" rel="nofollow noreferrer">http://www.3gpp.org/ftp/Specs/html-info/0340.htm</a>), but haven't been able to find much. Also, the fact that one has to provide the phone model indicates that it is a provider specific thing and not standardized?</p>
  
  <p>Does anyone have any pointers for me? Also I'd be interested how the "internet-enabling" process looks like in other countries. Anyone care to share?</p>
