Wi‑Fi Calling lets you make and receive calls over a Wi‑Fi connection instead of using mobile towers. It’s useful abroad if your carrier supports it.
On iPhone
- Go to Settings → Cellular → Wi‑Fi Calling.
- Toggle Wi‑Fi Calling on This iPhone → ON.
- Follow the on‑screen prompts to confirm.
On Android (varies by device)
- Open Settings → Network & Internet (or Connections on Samsung).
- Look for Wi‑Fi Calling.
- Toggle it ON.
- If asked, choose whether to prefer Wi‑Fi or Mobile Network for calls.
Notes
- Not all carriers support Wi‑Fi Calling — check with your provider if the option doesn’t appear.
- Wi‑Fi Calling may still use your home SIM, so charges can apply depending on your carrier’s rules.
