Roaming: You cannot use NumberSync outside of the U.S., Puerto Rico, or U.S. Virgin Islands. Due to technical limitations, calls using NumberSync cannot be used with TTY devices and will not support 911 TTY calls. Instead, dial 911 with a TTY from a wireless phone on a cellular network or landline phone; or text 911 directly, where available; or call 911 through relay service using TTY or IP CTS from a wireless phone on a cellular network or landline phone; or use IP Relay or IP CTS from a capable device. Visit att.com/numbersync for more information.

911 Call Routing: 911 calls sent through your tablet are routed based on automatic location information obtained from your tablet. If you cannot be located using automatic location information, 911 calls will be routed based on the address you provide in the NumberSync settings of your tablet.
