AT&T can only actually do that account-splitting for its own subscribers, but it's working on ways to let other carriers do the same thing for Toggle users. Toggle's dual device personalities already work on devices from any carrier. To make split plans possible, AT&T is studying how it might share usage data for the corporate portion of a phone with other service providers, Hill said. It already delivers that information to its enterprise customers. Other carriers could use the same data to put together a bill for their subscribers.
Toggle can be useful beyond the classic corporate office environment, Hill said. For example, grade schools could build special profiles for each grade level, with different materials and assignments, and have the right profile pop up on a shared tablet when a student from that grade logged into it. For workers in the field who share a company vehicle, each could customize a device to his or her own preferences and needs and get those by logging in, Hill said.
"Where we're headed is ... profiles being driven out of the cloud," Hill said.
Toggle could save a lot of work and worry for enterprise IT departments, where concern about data security continues to grow, said Tolaga Research analyst Phil Marshall. And the idea of personalization could extend to many other areas, such as using multiple personas with different social-networking services, he said. "We're just hitting the tip of the iceberg on what can be done," Marshall said.
