   Watch these steps Done

2. 

   Switch on Wi-Fi Calling

   Scroll down to Wi-Fi Calling (written WiFi Calling on our phone) and tap the switch. It was off on our phone.

   Done

3. 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.

   Done

4. 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.

   Done

If you do not see this option

• You are asked for an emergency address Samsung says a pop-up can ask for your emergency contact information when you switch it on. Enter it and tap Save; you can change it later under Wi-Fi Calling, Emergency address. Sources: Turn on Wi-Fi Calling on Galaxy phones, How to activate Wi-Fi Calling on a Galaxy smartphone
• You are on AT&T in the US Samsung says that on AT&T phones VoLTE must be on before Wi-Fi Calling can be switched on. Source: Turn on Wi-Fi Calling on Galaxy phones

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. Choose Wi-Fi preferred. Source: How to activate Wi-Fi Calling on a Galaxy smartphone
• 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. Sources: Turn on Wi-Fi Calling on Galaxy phones, How to activate Wi-Fi Calling on a Galaxy smartphone

About this guide

Wi-Fi Calling routes calls over a Wi-Fi network, which helps in basements and buildings with a poor signal. Your carrier has to support it, so the switch is missing on some phones.

Good to know

No Wi-Fi Calling switch? Your carrier has not enabled it for your plan or this phone; ask them to switch it on.

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

In short: Phone app, three dots, Settings, Wi-Fi Calling on. No switch means no carrier support.
