Wi-Fi Calling: Advantages and Disadvantages of Voice over Wi-Fi
Key points
- Wi-Fi calling uses Wi-Fi for calls and texts, bypassing cellular networks.
- It improves call quality and enables calls in cellular dead zones.
- Requires a stable Wi-Fi connection; congestion can cause audio issues.
- Handover to cellular is not always seamless when Wi-Fi is lost.
What is Wi-Fi Calling?
Wi-Fi calling, also known as Voice over Wi-Fi (VoWiFi), is a feature that allows mobile phones to make and receive calls and texts using a Wi-Fi internet connection. This technology routes the communication through an IPsec tunnel and ePDG connection to the carrier's network, effectively bypassing the traditional cellular network for the initial leg of the call.
Advantages of Using Wi-Fi Calling
One primary benefit of Wi-Fi calling is its ability to provide service in areas with poor or no cellular coverage, such as cellular dead zones often caused by building materials like thick concrete or metallic coatings. It also generally offers better call quality compared to cellular networks, especially when cellular obstructions, tower congestion, or fluctuating signals are present. Wi-Fi calling can provide HD voice quality on a strong connection.
Disadvantages and Limitations
Despite its advantages, Wi-Fi calling is not without drawbacks. It relies heavily on a stable and uncongested Wi-Fi connection; network congestion can lead to choppy audio, lag, or dropped calls. While the feature is designed to seamlessly switch to cellular networks if the Wi-Fi connection is lost, this transition is not always reliable in practice.
Ease of Use and Cost
Wi-Fi calling is typically easy to enable and use, requiring no special apps or additional costs on most carrier plans. It activates automatically when needed, and the recipient of the call does not need to have Wi-Fi calling enabled for the feature to function.

Reporting from
Wi-Fi calling routes phone calls and texts over a Wi-Fi connection instead of a cellular network, offering improved call quality and coverage in dead zones. However, it requires a stable Wi-Fi connection and can suffer from congestion, leading to choppy audio or dropped calls.
