Your device may support dynamic text messaging services that enable you to send Short Message Service (SMS) and Multimedia Message Service (MMS) messages. An SMS message is a text message that contains text only, with letters, numbers, and symbols. An MMS message is a text message that includes any of the following:
- Color background
- Attachments of any kind
- Subject line
Notes
Text messaging is an option that your mobile service provider might require that you pay for. Before you can send and receive text messages, your mobile service operator must activate your text-messaging account.
Text messages are automatically received when your device is turned on. When your device is off, messages are held by your service provider until the next time that the device is turned on.
