In short

Open the Phone app, tap the three dots, Settings, and switch on Wi-Fi Calling. The switch only appears if your carrier supports Wi-Fi Calling on your plan. Your phone then calls over Wi-Fi where the mobile signal is weak.

If you have ever finished a call standing by the window with one arm up in the air, try Wi-Fi Calling. It lets you call and take calls over Wi-Fi when there's no mobile signal. Not every network and phone offers Wi-Fi Calling, though, so some phones don't have the switch.

    Choose when Wi-Fi is used

    Tap Wi-Fi Calling itself to choose between Wi-Fi preferred and Mobile network preferred. Samsung lists these two options; we left the feature off and did not open them.

    Or use the quick panel

    Samsung's guide also shows a Wi-Fi Calling button in the quick panel: swipe down twice from the top and tap it. It appears only where the carrier supports the feature.

If you do not see this option

If this does not work

  • The switch is on, but calls still use the mobile network Samsung says calls follow the preference: with Mobile network preferred, Wi-Fi is only used when there is no mobile network. To have calls use Wi-Fi, choose Wi-Fi preferred.
  • It does not work at all Samsung says the phone must be connected to Wi-Fi with a strong signal and have an active SIM or eSIM, and the carrier must have Wi-Fi Calling activated on your account.
  • You see a roaming option instead? Samsung says some networks make you tap Roaming network preference or When Roaming to choose how calls work abroad.
  • Still nothing after checking the basics? Samsung also lists an up-to-date emergency address and a phone software version that supports the feature. Check that your phone's software supports the feature, then contact your carrier if it still fails.

Good to know

No Wi-Fi Calling switch? Ask your network whether it offers Wi-Fi Calling and whether it's switched on for your phone.

Samsung's US guide puts the switch under Settings, Connections, Wi-Fi Calling instead; look there if the Phone app has none.

Wi-Fi Calling needs an active SIM or eSIM and a strong Wi-Fi connection. Wi-Fi dropping? Samsung Galaxy Wi-Fi keeps disconnecting? 6 things to check.

Samsung says that if the network you prefer isn't there, the phone switches to the other one by itself. To undo it, tap the switch again. If calls are missing entirely, see why calls go straight to voicemail.
