# @ohos.telephony.sms (SMS) (System API)

The **sms** module provides basic SMS management functions. With the APIs provided by this module, you can create and send SMS messages, obtain the ID of the default SIM card used to send and receive SMS messages, and obtain and set the SMSC address.

>**NOTE**
>
>The initial APIs of this module are supported since API version 6. Newly added APIs will be marked with a superscript to indicate their earliest API version.
>
>This topic describes only system APIs provided by the module. For details about its public APIs, see [@ohos.telephony.sms (SMS)](js-apis-sms.md).
