Turning on Wi-Fi Calling
Go to Settings > Phone > Wi-Fi Calling
Is it working?
When Wi-Fi calling is working the status bar will show your status bar will show "AT&T Wi-Fi" (or Verizon or T-Mobile, yada, yada, yada.)
It Doesn't Work...
Sometimes Wi-Fi calling doesn't work unless the network settings are reset. Here's the procedure:
Note: Wait two minutes before you go from one step to the next.
- Go to Settings > Phone > Wi-Fi Calling and make sure that Wi-Fi Calling is on.
- Restart your iPhone.
- Turn Wi-Fi Calling off and then on again.
- Go to Settings > General > Reset
- Tap Reset Network Settings.
Your status bar should show "AT&T Wi-Fi", now. If not, contact your provider. Most providers offer free assistance.
