We have introduced Wifi Calling before, which is a service for your iPhone that gives the ability to make and receive phone calls over a Wi-Fi connection. Wi-Fi calling is a free service when calling to a US, US Virgin Islands or Puerto Rico number. International rates still apply for international numbers. It’s easy to use, and all of your domestic calling are at no extra charge.
Apple’s latest iOS 8.3 update expands the WiFi calling feature to two new carriers: Sprint in the United States and EE in the United Kingdom.
According to Sprint’s website, the feature will be available after installing the iOS 8.3 update. Once your iPhone updated, a prompt will appear asking you to install “Carrier Update” (Carrier settings updates are small files that can include updates from Apple and your carrier to carrier-related settings, such as network, calling, cellular data, messaging, personal hotspot, and voicemail settings. ) You can also check the version of the carrier settings on your device has, just tap Settings > General > About and look next to “Carrier”. The latest Sprint Carrier Version is 19.1.
To enable Wifi calling on your iPhone, simply toggle on Wi-Fi calling in the “Phone” section of the Settings app, which will let them make calls over Wi-Fi when a Wi-Fi network is available. Wi-Fi calling can be useful when cellular signal is low, and calls also have improved sound over Wi-Fi.
For EE users, to enable WiFi calling is a similar process in the United Kingdom. The subscribers will also need to update their device to iOS 8.3 and then enable WiFi calling in the Settings app, after which the feature will be activated in a few hours. EE’s limiting the number of iPhones able to register for WiFi calling to 100,000 per day, so there may be a waiting period for some users.
