SMS alerts deliver scheduled-task failure notifications by text message for urgent visibility. Quantity, phone-number, and billing specifics are evaluated on the official source.
Verified failure foundation
The evidence-backed foundation is failure behavior, not SMS mechanics: server unavailability can trigger retry attempts before an alert, and task information includes logs and the latest response body. SMS evaluation builds on that verified behavior without inventing channel details.

Not confirmed from current public documentation, so not asserted here: SMS delivery guarantees, phone-number quantity limits, country/carrier coverage, message templates, escalation rules, and prepaid account mechanics. SMS pricing and billing claims are omitted from this page until product-owner validation is recorded.
SMS workflow evaluation
SMS should be reserved for failures that need fast human attention. Decide which events deserve SMS, who receives the message, what detail is safe to include, and how the recipient moves from SMS to application logs.
- Which scheduled task failures are urgent enough for SMS?
- Which role or phone number receives the first alert?
- What content is safe in a short message?
- What escalation path follows repeated failures?
- How should non-business-hours alerts be handled?
- What validation record clears external SMS claims?
Relationship to Failure Alerts
The Failure Alerts page explains retry-before-alert behavior and channel boundaries. This page stays narrower: SMS-specific workflow planning. For current pricing and notification information, refresh and use the official sources.
