Longtime macrumors forum member, but I usually use the MacPro forums. This is my first iPhone issue. I have an iPhone 6 on ATT. At my house, my ATT signal is crumby. Last night, my phone missed calls all night, which is a big problem for my work. Is it possible to configure the iPhone such that even if the phone has no cell signal, calls can be received through the wifi signal? I know I can use wifi to call out through Messages, but I don't know whether it will receive calls in this way. Any help would be greatly appreciated. I would prefer to use Apple native software, but if I need to use Skype, etc., that would be OK as well.
