{"answer":"Confirm that the SIM is active, inserted in the correct orientation and size, has no unhandled PIN lock, and is provisioned for data. Check the account has allowance or credit and that the plan supports the required APN, roaming, static/public addressing or private network service.\n\nVerify the carrier has not restricted the SIM to an approved device type and that the antenna ports are correctly connected before powering the modem. Test the SIM in a known-working device where permitted. These checks separate account and provisioning problems from hardware faults and save unnecessary router resets.","approval_status":"draft_for_dave_review_pending_public_brain_audit","approved":false,"category":"Router Setup APN and Configuration","category_slug":"router-setup-apn-and-configuration","created_at":"2026-07-07T09:10:00+00:00","daily_publish_cap":2,"date_published":"2026-07-07","display_date":"2026-07-07","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-083","image_ids":["comset-support-router-login","comset-support-apn-settings","comset-support-australian-apn-table","comset-category-hero-028-router-setup-apn-and-configuration"],"language":"en-AU","last_updated":"2026-07-07T09:10:00+00:00","matched_image_ids":["comset-support-router-login","comset-support-apn-settings","comset-support-australian-apn-table","comset-category-hero-028-router-setup-apn-and-configuration"],"public_brain_verified":false,"publish_status":"review_preview","published_at":"2026-07-07T09:10:00+00:00","question":"What SIM, PIN, plan and carrier settings should be checked before troubleshooting the router hardware?","question_intent":"public_guidance","question_type":"technical_context","real_image_mapping_status":"mapped_to_approved_comset_catalogue_v1_6","site_key":"comset","slug":"what-sim-pin-plan-and-carrier-settings-should-be-checked-before-troubleshooting-the-router-hardware","source":"Comset public website scrape and stable industrial-networking explanation","source_record_ids":["comset-source-0045","comset-source-0375","comset-source-0088","comset-source-0107"],"source_type":"client_source_plus_stable_explanatory_context","source_urls":["https://comset.com.au/faq","https://comset.com.au/videos","https://comset.com.au/router-comparison-table"],"tenant_slug":"comset","updated_at":"2026-07-07T09:10:00+00:00"}
