Metro Tuesday announced it has expanded cellular service to the K Line’s underground sections. “Our customers deserve a safe, convenient, and connected ride — and we’re pleased that cell service is now fully operational in the underground stations on the K Line,” Metro Board Chair and Whittier City Council Member Fernando Dutra said in a statement. The expanded cell service makes it easier to stay connected while at stations and onboard Metro trains, the company said. In addition, AT&T customers began receiving cellular service on the Regional Connector — Little Tokyo, Historic Broadway, Grand Ave Arts/Bunker Hill stations — in May. Metro expects T-Mobile and Verizon Wireless customers to have service on the Regional Connector as early as this fall.
