Although major U.S carriers like Sprint, T-Mobile, and now AT&T already have Wi-Fi calling for their customers, Verizon is the last major U.S. carrier that still needs to activate the feature for its customers. AT&T recently raised a big stink about Sprint and T-Mobile having enabled the feature without being approved by a special waiver from the FCC, but nonetheless, Sprint and T-Mobile have been reached out to by the FCC to complete the waiver, and Verizon has already went through that process and been approved.
Now that we're waiting on Verizon, if you're a Verizon subscriber, you'll be happy to know that Verizon has announced this week its plans to enable Wi-Fi calling on its network for iPhone users early next year, although no specific date has been verified. On the other hand, owners of the Samsung Galaxy S6 and Samsung Galaxy S6 Edge will be able to start using Wi-Fi calling on the Verizon network as early as next week via a software update.
Wi-Fi calling is a great feature that allows users to tap into the power of Wi-Fi when their cellular signal is low, such as when inside of metal buildings or just when far away from civilization where there aren't so many cellular towers around. This allows you to maintain your crisp and clear call quality even when you're not in reach of a cellular tower and prevents breakups and call dropping.
