Setting up your Cingular mobile phone to receive SMS messages, otherwise known as text messages, will enable you to stay in contact with your friends and family. SMS messages are short messages, usually no more than 160 characters long. In the event that you cannot talk or do not want to talk in public, opting to send an SMS message is more efficient. Setting up SMS messages is easily done with a Cingular SMS capable phone.
