The table retains its October 1, 2026 source baseline except for the Home Internet hours cell, which now points to the refreshed guide rather than retaining the old “Not listed” wording. The refreshed 5G Home Internet guide now provides a separately checked dedicated-support context. Read its exact scope and source dates before choosing a channel. Customer service and Fiber remain the retained source-only editions.

The 5G Home Internet guide separates its published 24/7 call/message wording from general Customer Care and T-Life app/chat contexts. It also explains a navigation-link discrepancy while keeping the corroborated technical-support number. These are signposts to that guide, not renewed phone-source checks or measured availability. They establish no general Fiber hours, phone menu, wait or actual endpoint.
Navigation inspection: 2026-10-05T09:45:05Z. The Home Internet destination pin and hours-cell signpost changed. All other company-table cells, the source URL/date, 611 prerequisite and other destination links remain unchanged. All five historical reference declarations and clocks are retained; the current Home Internet guide and immediate prior hub are separately pinned. This edition follows the telephone standard [current article]; the exact previous hub [current article] preserves original extraction and attribution.
Recheck these links after a changed destination, before reliance or by 2026-10-12T09:45:05Z. This clock measures Wiki5 navigation inspection, not telephone-source freshness or successful contact. 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/context without private customer details.
