SMS
Texts from your Twilio number or from this phone's own SIM.
Two ways to text. From a Twilio number, with send_sms_twilio, which needs a number bought on Twilio (a verified caller ID cannot text). From this phone's own SIM, through phone control, where Send texts and Read texts are separate switches; reading lets a bot pick up the OTP a site just sent you. Call lists use SMS or WhatsApp for the follow-up text after a first miss. Slack, Notion, Linear and hundreds of other services are not channels: they connect as MCP servers under Project → Connectors.
