Trump Mobile, the wireless venture backed by the Trump Organization, has postponed delivery of its long-promised gold-colored T1 smartphone beyond the end of the year, blaming the latest U.S. government shutdown for the delay. The move extends a months-long slide in its launch timeline and underscores the operational challenges of turning a political brand into a mass-market hardware business.​​

Customer service representatives for Trump Mobile told Fortune the shutdown had disrupted shipments of the $499 device, and said while the device would not be shipped this month, “we’ve been told mid to late January.” The company has not publicly provided a revised delivery date.

​​”The T1 has been delayed due to the government shutdown. They had to pause everything on the FCC side of things,” the customer service rep said, adding the $499 price has not changed.

Trump Mobile was unveiled in June as a licensing venture that uses the Trump name to sell mobile service and a branded Android handset, the T1 Phone. The device is marketed as a gold-colored smartphone priced at $499, available via preorder with a $100 down payment. It is designed to run on “The 47 Plan,” a $47.45-per-month offering that bundles 5G service with unlimited talk, text, and data, the pricing a nod to Donald Trump’s status as the 45th and 47th U.S. president.
