However, with HD Voice over a cloud phone system, you can have effective business communication with your team using much higher quality sound and clarity than cellular service. In this guide, we’ll address the common questions regarding wi-fi calling.
What is Wi-Fi Calling?
Wi-Fi calling lets you place and receives voice calls, free texting, and video calls over a Wi-Fi network instead of a cellular network. It is a built-in feature on most smartphones. Consider using this feature if the cellular network service is weak or unavailable and Wi-Fi is available.
The IEEE and the Wi-Fi Alliance established several standards for wireless connections. So if you have a high-speed broadband connection, there is a good chance that you also have a router.
"WiFi calling is recommended for business use since it has several advantages over conventional cellular calling. WiFi calling eliminates the need for additional hardware or services and enables flawless communication even in locations with weak cellular coverage. By using low-cost or free WiFi networks for communication, WiFi calling can lower the costs associated with international calling. WiFi calling offers an additional layer of security for confidential business interactions over standard cellular calling by encrypting data transmissions. Overall, using WiFi calling can increase security, lower costs, and increase corporate productivity."
The range of a wireless router is typically about 150 feet, depending on the building materials used, and Wi-Fi calling provides the ability to use a wireless internet connection to make phone calls. Moreover, Android and iOS devices now support universal APIs (application programming interfaces) for VoIP calls, which optimize battery life and user experience.
It is imperative to have a backup connection to ensure business continuity. If your company’s wireless network fails, you must be able to conduct business over an LTE-based cellular network. It works over both networks when appropriately configured.

The free phone number call app such as DialerHQ allows businesses to make Wi-Fi calls from any device even if it doesn’t have cellular service.
Centrally, Wi-Fi calling utilizes VoIP technology to provide a better caller experience. As a result, you can choose the right plan and second number to meet your business needs, and it avoids paying your cellular company high international calling rates. In addition, thanks to modern wireless router advancements, you can leverage reliable network connections without any dropped calls.

Cellular Data vs. Wi-Fi Calling: What’s the difference?
Wi-Fi Calling makes it possible to talk to people who live in remote areas. You do not need to be near a cell phone tower. You just need an internet connection.
While Wi-Fi can provide a faster connection, the quality of voice can be affected if many people use Wi-Fi simultaneously, which is often the case in crowded places such as shopping centers or stadiums.
Wi-Fi calling has the disadvantage that your network can disrupt your call, among other problems related to VoIP. These issues are preventable, but those with poor network connections may experience echoes or delays.
Due to Wi-Fi congestion, video calls over Wi-Fi may suffer. Because of this, it might not be the best option for remote employees stuck in airports with overcrowded Wi-Fi connections. Most likely, they’d have a stronger cellular connection since cellular coverage areas are more reliable in urban areas.
Additionally, Wi-Fi calls can extend the battery life of your device. Using Wi-Fi calls consumes no battery, whereas a device constantly searching for a cellular network to connect to does. It connects to one network and stays there until you disconnect.
