About using UMA with a Wi-Fi network

UMA (also known as GAN) is designed to improve service and prevent dropped calls in areas of limited or no mobile network coverage by automatically switching between the mobile network and available Wi-Fi® networks. If your wireless service provider supports UMA and you subscribe to this service, you might be able to make calls, visit webpages, and send and receive email messages, PIN messages, and text messages over a Wi-Fi network.

For more information about UMA, contact your wireless service provider.
