Utilizing Wi-Fi Calling during Mobile Network Outages
Wi-Fi calling is an innovative feature that allows you to make calls and send texts over a wireless internet network, offering several advantages over traditional cellular calls.
A Modern Solution for Improved Connectivity
In areas with poor cellular coverage, such as basements, office buildings, or rural locations, Wi-Fi calling can be a game-changer. By routing calls over Wi-Fi rather than relying on weak mobile signals, it ensures uninterrupted communication.
Cost Savings and Flexibility
One of the most significant benefits of Wi-Fi calling is the potential for cost savings, particularly for international and roaming calls. Since it uses an internet connection rather than cellular network minutes, it often eliminates extra charges.
Superior Call Quality and Stability
Wi-Fi calling can deliver cleaner audio and a more stable connection, particularly when networks are congested or cellular signal is unstable. This results in better call quality and fewer dropped calls.
Operator-Independent Flexibility
Wi-Fi calling offers users more flexibility and control over communication costs, as it is not dependent on a specific cellular operator or tariff. This makes it an ideal solution for travelers and remote workers who wish to avoid roaming fees or the need for local SIMs.
Emergency Calling Capabilities
Many services support emergency calling via Wi-Fi networks, expanding coverage options beyond cellular networks. However, it's essential to register an emergency address for 911 calls to ensure accurate routing during WiFi-calling emergencies.
Technical Aspects of Wi-Fi Calling
Wi-Fi calling uses Voice over IP (VoIP) technology and requires compatible devices and carrier support. It establishes secure tunnels (e.g., IPSec) between the phone and the carrier, maintaining call security while leveraging Wi-Fi infrastructure.
Considerations for Using Wi-Fi Calling
To enjoy the benefits of Wi-Fi calling, it's crucial to ensure a stable WiFi network with at least 1 Mbps speed to avoid dropped calls or poor quality. It's also important to check if your phone company allows Wi-Fi calling on your plan before enabling it.
While Wi-Fi calling does not incur any extra charges, it could potentially use more battery on your device. Therefore, it's recommended to ensure your device has a good charge before relying on Wi-Fi calling for extended periods.
Not all phones can do Wi-Fi calling; most newer Samsung, OnePlus, Google Pixel, and iPhone 6 and newer models are compatible. To enable Wi-Fi calling on an iPhone, go to Settings > Cellular > WiFi-Calling, and on Android devices, go to Settings > Connections > WiFi-Calling.
When Wi-Fi Calling Shines
Wi-Fi calling is useful in situations such as when the network is down, in dead zones, while traveling, and on planes with Wi-Fi. However, emergency calls such as 112/911 might not work in all places over Wi-Fi, depending on your location.
In summary, Wi-Fi calling offers economic benefits, superior indoor coverage, call quality improvements, and operator-independent flexibility compared to traditional cellular voice calls. However, it depends entirely on the availability and quality of Wi-Fi connectivity where the user is located.
