“If you have an iPhone 6 (or 6 Plus) on T-Mobile’s network, Wi-Fi calls can be made and received exactly like cellular calls. And they will seamlessly be handed off to the cellular network when you leave Wi-Fi range, and vice versa,” Walt Mossberg writes for Re/code. “Also, on the new iPhones, the company’s improved-quality ‘HD calling’ will work on Wi-Fi calls, not just cellular ones.”
“T-Mobile calls this ‘Wi-Fi Unleashed,’ and I’ve been testing it — at home, and at public Wi-Fi hotspots in coffee shops, airports and hotels in Maryland and Massachusetts. In my tests, it worked just as advertised,” Mossberg writes. “My test T-Mobile iPhone 6 defaulted to placing all calls over Wi-Fi, if available, but with the same phone number the phone uses for cellular calls. These Wi-Fi calls could be made to any cellphone or landline phone, regardless of which network the other party was using.”
“There’s no special app to use, just Apple’s standard Phone and Messages features. And T-Mobile doesn’t charge extra for this service, or count Wi-Fi voice calls against your data usage. They do count against voice minutes, but the carrier notes that most of its current plans include unlimited voice minutes,” Mossberg writes. “And T-Mobile says the built-in Wi-Fi calling capability works overseas, so you can avoid cellular roaming charges.”
