If you’re a T-Mobile customer, your company just gave you a very unexpected gift at yesterday’s UnCarrier event: a wireless router. Yes, a fully functioning, magenta-branded, ASUS-built router, which can do essentially everything your current router can do — and if yours is old, this will likely do even more. The device, which would cost roughly $200 if you purchased it on Amazon without T-Mobile’s tweaks, only requires a $25 deposit, which gets returned to you once you’re done using it. The company is going all-in on its commitment to providing every subscriber and every carrier-branded smartphone with free WiFi calling, and the router — called the T-Mobile Personal CellSpot — is the icing on the cake. But, you may ask, why is this a thing that’s happening in the year 2014, especially when most of us already have access to a router (and thus, WiFi calling) nearly everywhere we go?
