NEW YORK — The Trump family said it is licensing its name to a new mobile phone service, the latest in a string of ventures that have been announced while President Donald Trump is in the White House, despite ethical concerns that the president could mold public policy for personal gain.

Eric Trump, one of the president’s sons running The Trump Organization, said the new venture, called Trump Mobile, will sell phones built in the U.S., and that the phone service will maintain a call center in the country as well.

The announcement of the new mobile phone and service, called T1 Mobile, follows several real estate deals for towers and resorts in the Middle East, including a golf development in Qatar announced in April. A $1.5 billion partnership to build golf courses, hotels and real estate projects in Vietnam was approved last month, but the deal was in the works before Trump was elected.

Trump has already used the federal government to reward his allies and punish his enemies. The Federal Communications Commission, the primary regulatory body overseeing mobile phone companies, has already launched investigations of media outlets Trump dislikes and, in some cases, is personally suing.

The company on Monday said the new, gold-colored T1 Phone, which will be available for $499 in August, won’t be designed or made by Trump Mobile, but by another company it did not identify.

The service, which will cost $47.45 a month, is partnering with existing cellular carriers with access to a 5G network.

Trump’s media company also announced Monday that it had filed a registration statement with the Securities and Exchange Commission to launch a new exchange-traded fund tied to the prices of the two most popular forms of cryptocurrency.

Trump Media & Technology Group, which operates the Truth Social media platform, said the planned ETF will have 75% of its assets in bitcoin, the world’s most popular cryptocurrency, and 25% in ether, the second-most popular.
