Help My phone cannot make wi-fi calls

[ShiroChu]

When I turn on wi fi calling and turn off my cellular network, I am able to connect to the internet and use my browser, but I cannot make a call. It says "mobile network not available." This is an issue because I cannot receive multimedia messages unless I am on wi fi. Does anyone have any advice?

It think the Samsung Galaxy Light aka Samsung Garda was a T-Mobile/Metro PCS exclusive in the US. So here are their instructions for Wi-Fi calling on your device on that network.

To use Wi-Fi calling, you must first register an E911 address and turn on Wi-Fi to connect to a Wi-Fi network.

1. Register your E911 address at My T-Mobile.
2. Turn on Wi-Fi.
3. From any Home screen, tap the Menu key.
4. Tap Settings.
5. Tap the Connections tab.
6. Tap More networks.
7. Tap the Wi-Fi Calling Switch to On. The Switch moves right and turns green.

Set connection preference
