What Is WiFi Calling? Full Guide for Android and iPhone Users

Wi-Fi calling is changing the way we communicate, providing easier ways to make and receive calls without depending on cellular networks. With increasing reliance on strong, continuous connectivity, particularly in areas with weak cell service, Wi-Fi calling has become a turning point for important conversations.

As of early 2023, more than 60% of mobile users in the US have Wi-Fi calling support, making it an important feature for many smartphone users. This transition shows its increasing necessity as a good option for better communication.

In this guide, I am going to explain how Wi-Fi calling works, the benefits it has, and how you can enable it on your Android or iPhone with little effort.

What Is WiFi Calling?

Wi-Fi calling enables you to make phone calls and send texts over a Wi-Fi network instead of using cellular service. This feature is particularly useful when you are in locations with poor cellular service.

Wi-Fi calling generally works by directing your calls over an internet connection, resulting in good call quality and service. It is compatible with most modern smartphones, including Android and iPhone devices, and can give you better call quality in areas with weak cellular signals.

Many users depend on this feature to stay in touch, particularly while stuck inside a building with a weak connection or while travelling in remote areas.

How Does WiFi Calling Work?

Wi-Fi calling uses a Wi-Fi network instead of your device's cellular network for placing and receiving calls, sending text messages, and accessing other services. It easily connects your device to the internet, using a voice-over-IP (VoIP) system to address the call, rather than depending on a mobile network.

So, you might have a doubt that “What happens if my phone detects a Wi-Fi signal in the middle of a call?”

Simple, it immediately switches to Wi-Fi calling from a cellular network, allowing you to take the call with better quality. This showcases how important Wi-Fi calling is, whether you are at your home, in a coffee shop or in areas where there is no proper network coverage.

Wi-Fi Calling: Is It Free or Charged?

Wi-Fi calling is usually free when you are connected to a Wi-Fi network, as it uses your internet connection instead of your mobile carrier's cellular network. However, be mindful of your internet data usage, as some internet providers may charge you for excessive data usage.

For international calls, Wi-Fi calling can still be a cheap option. Some carriers offer Wi-Fi calls to international numbers at the same cost as domestic calls, while others may apply international rates, which are typically lower than traditional roaming charges.

WiFi Calling vs Regular Cellular Calls

Here’s a clear comparison between Wi-Fi calling and regular cellular calls, showing the key differences. This table will help you see how both methods function and the benefits of each:

Benefits of WiFi Calling

WiFi calling has a number of advantages that make it a great option for mobile users. Here are some key benefits:

• Improves Call Quality: WiFi calling offers better audio quality, even in places where cell phone service is poor. It uses your WiFi network to provide more stable call quality, reducing dropped calls and background noise.
• Cost Savings: WiFi calling can also lower your phone bill. Calls made over WiFi do not use any cellular minutes, allowing you to make international calls for free.
• No Need for Cellular Signal: If you have a poor or no cellular signal in your area, WiFi calling enables you to make and receive calls without any problems, as long as you have access to a strong WiFi network.
• Seamless Connectivity: WiFi calling helps you stay connected when you are in a place with poor cellular coverage, like basements and remote areas, as long as there’s a strong WiFi signal available.

Limitations of WiFi calling

While Wi-Fi calling is beneficial, it comes with certain limitations that you should be aware of. Here are some key drawbacks:

• Needs stable Wi-Fi and a strong Wi-Fi signal, with a poor signal causing dropped calls or poor sound quality.
• Limited to areas where Wi-Fi is accessible, ineffective in places with no coverage or weak internet.
• Wi-Fi calling won't work with all devices or carriers, so compatibility checks are important.
• Wi-Fi calling may not provide accurate location information to emergency services.

Which Devices Are Compatible with Wi-Fi Calling?

Wi-Fi calling is available on almost all new smartphones, which allows you to make clear calls through a Wi-Fi network. Here’s a list of devices that currently support Wi-Fi calling:

For Androids:

• Samsung Galaxy S series (S6 and above)
• Google Pixel series (Pixel 2 and above)
• LG G6, V20, and newer models

For Carrier-Specific Phones:

• Devices from carriers like T-Mobile, Verizon, and AT&T may have Wi-Fi calling turned on by default on specific models.

Best Practices to Ensure Seamless WiFi Calling

For the best WiFi calling experience, it is important to follow specific guidelines. This will help you avoid issues and ensure clear communication. Here are the key best practices for smooth WiFi calling:

Choosing the Best WiFi Network for Calls

To get good call quality, it's best to use a fast and reliable WiFi connection. Networks that are slow can cause call drops and sound problems. Always use networks with high bandwidth and little interference for the best WiFi calls. If possible, pick 5GHz WiFi over 2.4GHz for faster performance and better call clarity.

Adjusting WiFi Calling Settings

Activate WiFi calling in your device's settings for a better call experience. Modify network settings to switch between WiFi and cellular connections when required. Customise advanced settings such as call preferences to prioritise WiFi calling when accessible and enhance your device's connection.

Ensuring a Strong Signal for WiFi Calling

To make Wi-Fi calling better for you, optimise your network for better performance. Weak connections can result in poor audio and call quality issues. Here’s how to make your network better:

• Positioning: For a stronger signal, stay near your router. Don't use your phone where signals are poor, such as in basements or corners of the house.
• Avoid Interference: Keep your phone away from things that might disrupt the signal, like microwaves or thick walls.
• Upgrade Your Router: If your router is old, try purchasing a new one that provides faster speeds and stronger signals for easier calls.

WiFi Calling on Public Networks

Public WiFi can be less secure and may not offer the best speeds for calls. For improved security and performance, it's better to use a private and reliable WiFi network, especially during important calls.

Troubleshooting WiFi Calling on Your Device

Though WiFi calling is very convenient, it can sometimes fail. To resolve any problems with WiFi calling, try these troubleshooting steps:

Ensure Wi-Fi Calling is Enabled

Ensure WiFi calling is activated on your phone. For both Android and iPhone, go to your "Mobile Network " or "Cellular" settings to switch on WiFi calling. If calls still don't work as expected, you might need to check your connection's stability.

Reset Network Settings

If WiFi calling isn't working, try resetting your network settings. Doing this will restore your WiFi, Bluetooth, and cellular settings to their default state, fixing any configuration problems that may be affecting your WiFi calling.

Update Your Device’s Software

Sometimes old software can prevent WiFi calling from working properly. Be sure to look for updates on your device. If you experience frequent connectivity problems, it might be beneficial to use tools that monitor your network's performance regularly.

Using Qoli for Better Control

If the above methods fail, try using network monitoring tools such as Qoli to gain control over your WiFi connections. It provides advanced features for identifying and fixing network problems that can impact WiFi calling.

With Qoli, you can:

• WiFi Blocking: Block certain WiFi networks from disrupting your calls.
• Detailed Logs: Review detailed records of WiFi network behaviour, covering IP addresses and connection times.

Conclusion

Wi-Fi calling delivers better call clarity and often reduces expenses, especially where call signals are low. By applying these best practices and using troubleshooting techniques, you can maximise the benefits of Wi-Fi calling and enjoy smooth calls. Use this technology to stay connected and enhance your calling experience, no matter where you are.
