The Home Internet guide separates its published call/message wording from general Customer Care and T-Life app/chat contexts, and explains a navigation-link discrepancy. The Fiber guide now documents the general Fiber support page's phone-hours context; its earlier text-extraction loading screen did not establish absence of hours. Keep those product and channel scopes separate. These are signposts to exact guides, not renewed company-source checks, measured availability, menus, waits or successful contact.

Navigation inspection: 2026-10-05T09:59:37Z. This edition changes only the Fiber destination pin and Fiber hours-cell signpost, plus dated navigation context. All other company-table cells, the source URL/date, 611 prerequisite, Customer Care and Home Internet links remain unchanged. All eight prior reference declarations and clocks are retained; the current Fiber guide and immediately preceding hub [current article] are separately pinned. That prior edition retains the Home Internet navigation check and earlier attribution. This follows the telephone standard [current article].

Recheck after a changed destination, before reliance or by 2026-10-12T09:59:37Z. This clock measures Wiki5 navigation inspection, not telephone-source freshness. Eight author navigation decisions were manually checked; a distinct same-operator checker rechecked those decisions and added five manual boundaries, with no independent formal coverage. No call, account, chat, contact or transaction occurred. Feedback should identify the exact affected link or service context without private customer details.
