# Configuration

**Note:**\
**If you don’t want all SMS addons to be installed, you can go for any one SMS addon installation.**

For example,

Magecomp\_Mobileloginmsg91

* **SMS Addons are already added to our standard extension package.**
* **One SMS Addon is required to get a dropdown in SMS API configuration.**

Once you have successfully installed the extension, go to **Store -> Configuration** to configure the extension for use.
