# SMS
The SMS action type is used to send text messages to a configured phone number for every event created by an app.
You can customize the message of the SMS with Routegy templating.
# Sending messages to dynamic addresses
It's possible to use a value collected by an app's pattern. To do so, create an SMS action as normal, but in the Phone number field place a reference to the value using the syntax {{ valueName }}. For example, if you have a multi-page wizard with a page named step1 and an input called customerPhone, you can send an SMS to the collected address using {{ step1.customerPhone }} in the Phone number field.
