How to Use Airplane Mode and Wi-Fi Calling on Android

/ How-To Guides / By

Introduction

Airplane Mode and Wi-Fi Calling are two essential Android features that help stabilize connectivity, reduce battery drain, and maintain communication in places with weak mobile signals.
Airplane Mode disables all cellular radios instantly, while Wi-Fi Calling allows you to make and receive calls using a Wi-Fi network instead of relying on mobile towers.

Many users activate Airplane Mode without understanding its full impact or miss opportunities to use Wi-Fi Calling to improve call clarity.
This guide explains how these two features work together, when to use each tool, and how to optimize network settings for the most reliable experience.

By understanding the relationship between airplane mode android, wifi calling android, and overall android network settings, you can manage your device more efficiently and avoid unnecessary signal issues.

Step-by-Step Guide

Step 1: Understand What Airplane Mode Actually Does

Airplane Mode disables all wireless signals at once:

  • Mobile data
  • Cellular calls and SMS
  • Bluetooth
  • Wi-Fi
  • NFC

However, Android allows you to manually re-enable Wi-Fi and Bluetooth even when Airplane Mode is active.
This means you can stay offline for mobile networks while still using wireless headphones or connecting to the internet when needed.

Understanding this foundation helps you configure Airplane Mode properly instead of treating it as a complete shutdown function.

Step 2: Turn On Airplane Mode

Airplane Mode can be activated in seconds:

  1. Swipe down from the top of the screen.
  2. Tap the Airplane Mode icon.
  3. Wait for all cellular signals to turn off.

Once enabled, your device stops searching for mobile towers, which reduces battery consumption in low-signal areas.
If Wi-Fi and Bluetooth are required, you can enable them manually after activation.

Step 3: Re-enable Wi-Fi While in Airplane Mode

Many users do not realize this step is possible.
After activating Airplane Mode:

  1. Open Quick Settings again.
  2. Tap the Wi-Fi icon to turn it back on.
  3. Connect to your preferred network.

This configuration is useful on airplanes, in hospitals, or in locations where mobile radios must stay off but wireless internet use is allowed.

Step 4: Enable Wi-Fi Calling on Android

Wi-Fi Calling routes your voice calls and SMS over Wi-Fi rather than cellular networks.

To enable it:

  1. Open Settings.
  2. Tap Network & Internet.
  3. Select Mobile Network.
  4. Choose Wi-Fi Calling.
  5. Toggle Use Wi-Fi Calling to ON.

Your carrier and device must support the feature, but most modern Android phones—including Samsung, Pixel, and OnePlus—allow Wi-Fi Calling by default.

Step 5: Make Calls While Airplane Mode Is On

Once Wi-Fi Calling is enabled, you can make calls even if Airplane Mode is active.

The sequence is simple:

  1. Turn on Airplane Mode.
  2. Turn on Wi-Fi.
  3. Ensure Wi-Fi Calling is enabled.
  4. Dial any number normally.

The call will connect through your Wi-Fi network with stable quality, ideal for places with weak mobile coverage.

Step 6: Optimize Android Network Settings for Better Stability

To improve overall performance:

  • Keep Preferred Network Type set to LTE/5G.
  • Avoid constant switching between networks in low-signal areas.
  • Enable Adaptive Connectivity if supported.
  • Update carrier services regularly.

These small adjustments help maintain strong call quality when switching between Wi-Fi Calling and mobile networks.

Troubleshooting

Wi-Fi Calling Not Working

  • Check if your carrier supports Wi-Fi Calling.
  • Ensure Wi-Fi networks allow VoIP traffic.
  • Disable VPNs that block voice routing.

Calls Fail in Airplane Mode

  • Confirm Wi-Fi Calling is enabled in settings.
  • Ensure Wi-Fi is connected before dialing.
  • Restart your phone if settings do not refresh.

Poor Call Quality

  • Switch to a different Wi-Fi network.
  • Move closer to the router.
  • Disable battery saver modes that restrict network services.

Additional Tips

  • Use Airplane Mode in low-signal areas to prevent rapid battery drain.
  • Wi-Fi Calling can be used internationally depending on your carrier’s policy.
  • Combine both features to avoid roaming charges while staying reachable.
  • If your router supports QoS, prioritize voice traffic for clearer calls.

Final Notes

Airplane Mode and Wi-Fi Calling are not separate tools—they complement each other.
Airplane Mode reduces unnecessary radio activity, while Wi-Fi Calling ensures communication remains stable.
By mastering both settings, you can improve battery efficiency, strengthen call reliability, and use your Android device more intelligently in various environments.

Extra 1

In emergency situations, Wi-Fi Calling can be more reliable than mobile networks, especially inside buildings.
If your device frequently loses signal indoors, enabling Wi-Fi Calling ensures texts and calls continue to work without interruption.
For travelers, this combination is ideal because it prevents roaming charges while maintaining full communication capabilities.

Extra 2

Some Android devices automatically switch between Wi-Fi Calling and mobile calling depending on signal strength.
If you prefer calls to stay strictly on Wi-Fi, disable “Switch to mobile data for calls” under the Wi-Fi Calling advanced menu.
This ensures your device remains fully controlled and predictable, especially when using Airplane Mode as part of your daily routine.
