For starters, the company is now enabling Wi-Fi calling and texting on nearly every smartphone it sells to Simple Choice customers (Nexus devices not included, since they don't come with carrier modifications). T-Mobile users can also use any public or private Wi-Fi network in place of its cellular network. These calls are free, just as they've already been for people already accustomed to using T-Mobile's Wi-Fi calling.

Starting on September 17th, Simple Choice customers can get a T-Mobile Personal CellSpot router with a $25 refundable deposit that can serve parts of the home with poor coverage. If this sounds familiar, that's because carriers have been toying with the idea of using Wi-Fi to expand their coverage for quite a while using various approaches. Now T-Mobile's doing it too.

To round out the package, T-Mobile has also made a deal with Gogo to provide customers with free unlimited text messages and voicemail access on all Gogo-equipped flights on US-based airlines. This feature apparently explains the Wi-Fi calling enhancements we've seen pop up on firmware update change logs as of late. To take advantage of it, customers just need to enable in-flight texting once before boarding a plane. They can do so at t-mobile.com/gogophones.
