Any mobile phone you buy today should have at least SMS messaging
capabilities, and nearly all users of any age know how to send and
receive such messages.
• Android comes with a built-in SMS application that enables you to
send and receive SMS messages.
• However, in some cases you might want to integrate SMS capabilities
into your own Android application.
• For example, this would be useful if you wanted to track the location of your
kids — simply give them an Android device that sends out an SMS message
containing its geographical location every 30 minutes.
• Such a capability also means you would have to pay the fees incurred
from sending all those SMS messages.
