# Text Message Settings

You can set the text message settings, such as the prompt mode.

- Setting the Text Message Prompt
  If the text message prompt is set, an alert tone is played or a visual prompt is displayed when there is an incoming text message.
- Setting the SMSC Number and Message Validity Period
  For the first time to send a text message, the Short Message Service Center (SMSC) number needs to be set. The message validity period is the period in which text messages can be stored in the SMSC.
- Setting the Delivery Report
  When the delivery report is enabled, the network delivers a status report for the sent message.
