AT&T is launching its first 5G phone on June 17th, but only for business customers and a select group of developers. The company will offer the Samsung Galaxy S10 5G to customers on the new AT&T Business Unlimited Preferred plan, which includes 5G service. For a limited time, businesses can order the Galaxy S10 5G with 256 GB of storage through their AT&T account representatives for the discounted price of $1,000. The phone can access AT&T's mmWave 5G network, which is available today in "very limited parts" of 19 cities, with plans to reach parts of at least 30 cities. The phone cannot access 5G service at lower (sub-6 GHz) frequencies that AT&T has promised to launch by the end of the year. The company is also offering a group of developers a Galaxy S10 5G with free service through the end of the year.
