o YK is responsible for the maintenance and repair of the telecommunication lines and related network — at no additional charge — that are outside our customers’ homes or businesses. However, the wiring inside a customer’s home or business is the responsibility of the customer. YK does not repair telephone sets. If during a requested service call it’s determined that the problem is caused by your telephone set or inside wiring, and not our facilities, an applicable trip charge and repair cost will be imposed. To avoid any unexpected or expensive repair bills, YK offers a Wire Protection Plan. The service provides protection for inside your location. Contact us at 361-771-3334 to learn more.
