When to avoid Wi-Fi calling

Avoid it when..
Explanation
You are placing an emergency 911 call.  
  • Wi‑Fi calling may not automatically provide your precise location.
  • Especially risky if:
    • you’re traveling.
    • your address hasn’t been updated with your carrier.
    • you’re on hotel or public Wi‑Fi.
You are using public, unsecured, or unstable Wi‑Fi.
  • Risk of call drops or delays.
  • Potential traffic inspection (low risk, but not zero).
You are physically moving around (e.g., walking, driving).

When you move around, your phone keeps losing and re‑establishing Wi‑Fi connections.

  • Wi‑Fi can’t hand off calls smoothly the way cellular networks can.
  • This results in drops, glitches, or one‑way audio.
Your battery is low.

Wi‑Fi calling can use more battery than cellular, especially when the signal is weak.

How to enable Wi-Fi calling for Android (e.g., Samsung)

Step 1: Switch 5G to LTE

  1. Open Settings and tap Connections.
  2. Tap Mobile networks.
  3. Select Network mode.
  4. Choose LTE (auto connect). This prevents the phone from constantly searching for a weak 5G signal.

Step 2: Activate Wi-Fi Calling

  1. Go back to Settings > Connections.
  2. Tap the text Wi-Fi Calling (not just the toggle).
  3. Switch the toggle to On.
  4. Pro Tip: If your signal is truly terrible, look for Calling preference within this menu and set it to "Prefer Wi-Fi" so the phone doesn't even try to use the weak cellular tower.
