It’s official: Google is in the wireless business. On Wednesday, the company launched Project Fi, a wireless service that lets subscribers jog between the networks of T-Mobile, Sprint and Wi-Fi connections. It’s priced at $20 a month, with one gigabyte of data at $10 a pop; unused data will carry over to the next month. At the onset, the service is very limited: It only works with Nexus 6 phones. At Mobile World Congress in January, Android chief Sundar Pichai confirmed earlier reports of Google’s plans, but said the service’s scale would be limited. Still, the initiative, among several Google is pushing to remove impediments to speedy Internet access, will agitate the wireless industry.
