Can I make calls and use data services at the same time? You cannot use voice and data services simultaneously. If you receive a call while data service is active, the call will be forwarded to voicemail. You can place an outgoing call anytime, but it will interrupt any in-progress data session. When is my data connection active? Your connection is active when data is being transferred. Outgoing calls are allowed; incoming calls go directly to voicemail. When active, the or indicator animates on your phone's display screen. When is my data connection dormant? If no data is received for 10 seconds, the connection goes dormant. When the connection is dormant, voice calls are allowed. (The connection may become active again quickly.) If no data is received for an extended period of time, the connection will terminate. Can I sign out of data services? You can sign out without turning off your phone; however, you will not be able to browse the Web or use other data services. While signed out, you can still place or receive phone calls, check voicemail, and use other voice services. You may sign in again at any time. To sign out, go to Settings > More... > Data > On/Off in your phone's menu. 142 Section 3B:Web and Data Services
