What are the advantages of WiFi Talk & Text?

As long as you are connected to a local WiFi network, you will be able to use your mobile device to make/receive voice calls and send/receive SMS text messages, just as if it were on a normal cellular network. This means that you can use your service even when the wireless signal is limited. Another advantage of having the WiFi feature active on your account is to eliminate INTL roaming charges.  If you are roaming internationally with WiFi enabled, you will not be charged for any inbound or outbound calls that use a WiFi connection.  The same is true for sending SMS text messages.
