Sending advertisements via mobile phone is just one option when it comes to informing customers of your business or service. It's a method that should be used carefully, since many people have to pay to receive text or picture messages, and unwanted advertisements can cause your would-be customers to be seriously annoyed with you: not the best way to drum up business.

If you have a good reason for wanting to send advertisements via mobile phone, the best way to do this is to create a list.
Remember that your mobile phone provider may charge you to send text or picture messages, and when you send a message to a group, you will be charged for each member of the group to receive that message.
