# How Do I Send an Automatic SMS from My Bot with ChatSyncs?

> The SMS tab in Bot Settings — automatically sends a custom SMS to a subscriber the moment they share their phone number in a WhatsApp conversation.

The **SMS** tab in [Bot Settings](/learn/chatsyncs-bot-settings/introduction) automatically sends an SMS
to subscribers who share their phone number through this bot.

<Note>
  **SMS API** is a dropdown listing the SMS gateway profiles you've connected under [SMS
  Integration](/learn/chatsyncs-integrations/sms/introduction) — connect one there first, then select it here and write
  the Content this bot should send.

## Frequently asked

<AccordionGroup>
  <Accordion title="Do I need to connect an SMS gateway before I can use this tab?">
    Yes — connect one (Plivo, Twilio, Nexmo/Vonage, and others) once under [SMS
    Integration](/learn/chatsyncs-integrations/sms/introduction), then write the Content here.
  </Accordion>

  <Accordion title="What triggers this SMS to send?">
    The subscriber sharing their phone number during a conversation with the bot — there's no
    separate button to click.
  </Accordion>

  <Accordion title="Can I personalize the SMS content per subscriber?">

    messages.
