{"answer":"That depends on the router\u2019s failover rules and on how failure is detected. Some systems swap because the mobile connection drops outright. Others watch whether traffic can still reach a known destination, which is often more useful because a link can stay technically connected while being practically unusable. The transition may be quick, but the real question is whether the application can tolerate a short interruption while the router re-registers and re-establishes sessions.\n\nComset can help tune that behaviour for the job. An unattended monitor, an EFTPOS terminal and a site-to-site VPN tunnel may each need slightly different failover logic.","approval_status":"review_build_pending_public_brain_audit","approved":true,"category":"Dual SIM and Carrier Redundancy","category_slug":"dual-sim-and-carrier-redundancy","created_at":"2026-07-17T09:10:00+00:00","daily_publish_cap":2,"date_published":"2026-07-17","display_date":"2026-07-17","drip_status":"scheduled","freshness_note":"Confirm current specifications, carrier compatibility, stock, firmware, warranty and commercial terms directly with Comset.","id":"comset-qa-100","image_ids":["comset-product-cm950w","comset-product-cm510q-w","comset-category-hero-004-dual-sim-and-carrier-redundancy"],"language":"en","last_updated":"2026-07-17T09:10:00+00:00","matched_image_ids":["comset-product-cm950w","comset-product-cm510q-w","comset-category-hero-004-dual-sim-and-carrier-redundancy"],"public_brain_verified":false,"publish_status":"published_preview","published_at":"2026-07-17T09:10:00+00:00","question":"How quickly can a dual-SIM router move to the second SIM if the first network fails?","question_intent":"public_guidance","question_type":"conversational_public_guidance","real_image_mapping_status":"mapped_to_approved_comset_catalogue_v1_6","site_key":"comset","slug":"how-quickly-can-a-dual-sim-router-move-to-the-second-sim-if-the-first-network-fails","source":"comset_manual_review_v1_5","source_record_ids":[],"source_type":"manual_review_from_public_sources","source_urls":["https://comset.com.au/product/5g-4g-router-with-dual-sim-cm950w","https://comset.com.au/product/dual-modem-dual-wifi-gigabit-router-cm770w-6"],"tags":["manual","reviewed","customer_style"],"tenant_slug":"comset","updated_at":"2026-07-17T09:10:00+00:00"}
