{"answer":"SMS can be useful for status requests, controlled rebooting, changing between WAN and cellular paths, switching a supported relay output or reporting a digital-input alarm. Because SMS uses the mobile signalling path, it may still work when normal packet data or the remote VPN is unavailable.\n\nOnly functions explicitly supported by the router and safely connected equipment should be used. Physical control requires interlocks and a fail-safe design; an SMS command should not be the sole safety mechanism for machinery. Confirm the command syntax and model compatibility in the current Comset guide, and test how acknowledgements and errors are reported.","approval_status":"draft_for_dave_review_pending_public_brain_audit","approved":false,"category":"SMS Control Alerts and Automation","category_slug":"sms-control-alerts-and-automation","created_at":"2026-06-08T09:10:00+00:00","daily_publish_cap":2,"date_published":"2026-06-08","display_date":"2026-06-08","drip_status":"review_seed","freshness_note":"Confirm current model specifications, carrier compatibility, stock, pricing, firmware, warranty and commercial terms directly with Comset where they affect a decision.","id":"comset-qa-034","image_ids":["comset-product-comset-sms-app","comset-category-hero-012-sms-control-alerts-and-automation"],"language":"en-AU","last_updated":"2026-06-08T09:10:00+00:00","matched_image_ids":["comset-product-comset-sms-app","comset-category-hero-012-sms-control-alerts-and-automation"],"public_brain_verified":false,"publish_status":"review_preview","published_at":"2026-06-08T09:10:00+00:00","question":"What can an industrial router safely control or report through SMS when the data connection is unavailable?","question_intent":"public_guidance","question_type":"decision","real_image_mapping_status":"mapped_to_approved_comset_catalogue_v1_6","site_key":"comset","slug":"what-can-an-industrial-router-safely-control-or-report-through-sms-when-the-data-connection-is-unavailable","source":"Comset public website scrape and stable industrial-networking explanation","source_record_ids":["comset-source-0017","comset-source-0295","comset-source-0365","comset-source-0376"],"source_type":"client_source_plus_stable_explanatory_context","source_urls":["https://comset.com.au/product/comset-sms-app","https://comset.com.au/product/digital-io-board-4-relays-dio-004","https://comset.com.au/faq"],"tenant_slug":"comset","updated_at":"2026-06-08T09:10:00+00:00"}
