Enabling and Disabling Voice Calls
You can disable voice calls without turning off your
phone; however, you will not have access to both
incoming or outgoing voice calls. Disabling voice calls
will avoid any charges associated with minutes used or
roaming. While signed out, you cannot place or receive

services, but you can access the Web and use other

time.
