GET /phone/sms/sessions returns 400 "SMS session type is invalid" when using session_type=all

We're calling GET /phone/sms/sessions with session_type=all (documented as a valid value), but some accounts return a 400 Bad Request:

Error Code: 400
Message: SMS session type is invalid.

Questions:

  1. Under what account configurations or plan types would session_type=all be considered invalid?
  2. Is this returned when the account doesn't have SMS/MMS features licensed or activated?
  3. Is there a distinguishing error code so we can handle it gracefully in our integration?
