(CNN) -- T-Mobile wants to beef up its cell coverage by thinking small and piggybacking on your Internet service. The carrier is offering its customers a free personal cell spot -- a router that plugs into an existing broadband connection to improve mobile phone coverage while at home. All new smartphones purchased through T-Mobile will allow phone calls and texts over WiFi. And as mentioned in Apple's announcement Tuesday, T-Mobile will be the first carrier to support seamless switching between WiFi and cellular networks, so you don't have to hang up and redial when you leave the wireless area. For now, the switching capabilities will only be available for the iPhone 6 and 6 Plus.

That means that if someone is streaming video on a @placeholder network while another person wants to make a call, the video may be slowed so that the phone call gets more bandwidth.
