What happens if I step out of my Wi-Fi coverage area while on a call?
When you go out of range of your Wi-Fi coverage area your call will disconnect. You will need to re-dial after you are in cellular coverage or re-connect to another Wi-Fi network. Likewise, if you start your call on the cellular network and enter a Wi-Fi-only zone, your call will terminate.
Why does the quality of my Wi-Fi call vary?
Call quality cannot be assured with Wi-Fi Calling, as it is dependent on the Wi-Fi and Internet connection you are using. Cellular service provides higher assurance of call quality, since calls are on a dedicated spectrum, using carrier-grade equipment and maintenance. Wi-Fi Calling is configured to default to cellular service whenever possible to deliver the best quality calling experience.
Why does my phone default to cellular calling?
By staying on a cellular connection, the quality of service is always maintained. The quality of your calls over Wi-Fi Calling will greatly depend on your Wi-Fi connection to the Internet. Since Wi-Fi is shared with other devices and other Wi-Fi networks, it will be more prone to interference, which may cause call quality issues. As well, Wi-Fi Calling depends on the Internet quality and available bandwidth. Slow Internet connections and public Wi-Fi Hotspots tend to have very low Internet quality. Cellular networks do not have these interference issues. Bell's HSPA and LTE Mobile networks can provide a higher quality of service and better user experience.
Emergency calls will default to the mobile network whenever it is accessible and will be treated as usual. When the mobile network is not available, your emergency call will be sent to a call center that will ask you where you are calling from, then forward your call to the appropriate 9-1-1 response centre. If you are unable to verbally communicate your location, help will be dispatched to the address in your device settings. It is important that you update this address to reflect your most up-to-date whereabouts when you use Wi-Fi Calling.
In addition, T911 and special numbers (e.g., services offered to the public like 211, 411 and 311) are not accessible over Wi-Fi.
