Overview

Rent or attach phone numbers and wait for the SMS they receive.

Three kinds of numbers share one surface:

  • Twilio: virtual numbers you rent and keep.

  • Hero SMS: temporary numbers rented for minutes, for one-off SMS verification.

  • Mobile: real SIM cards in Android phones, attached to your project by scanning a QR code with the SIM Bridge app.

Whichever kind a number is, GET /list, POST /release and GET /sms/wait work the same. Provider-specific actions live under /providers/{provider}/…. The provider is chosen by the path, never by a parameter.
