After receiving a waiver from the FCC, it looks like AT&T has flipped the switch on Wi-Fi calling. All you folks with an eligible plan and device running iOS 9 can go into Settings and flip the switch.<\/p>\n
<\/p>\n
As the name suggests, Wi-Fi calling will allow subscribers to make and receive calls over Wi-Fi. If you have poor reception at your house, this is a huge deal.<\/p>\n
Once you do flip Wi-Fi Calling on, you\u2019ll have to go through a few steps and a short waiting period, including entering an emergency 911 address. If you want to use the feature, you have to have AT&T HD voice features enabled, along with a solid Internet connection.<\/p>\n
Update<\/strong>: We turned on Wi-Fi Calling, and it works great. Unfortunately, AT&T handles Wi-Fi Calling a bit differently, which means you likely won\u2019t get handoff capabilities when going from Wi-Fi to cellular. AT&T told us that it depends on network coverage in the area you live. If HD Voice is available when your Wi-Fi connection is lost, the call will handoff no problem. If not\u2014like where we are in Irvine\u2014your call will drop. The only time your call will continue is if you\u2019re making a 911 call. Here\u2019s a coverage map<\/a> to see if HD Voice is in your area.<\/p>\n
