T-Mobile is sponsoring 30 minutes of free Gogo Wi-Fi on your smartphone regardless of what carrier you currently use. This is good for September 3rd only on Gogo Wi-Fi enabled domestic flights.

It’s a smart move by T-Mobile who is pointing out that their current T-Mobile One customers receive free messaging, texting, and a free hour of smartphone Wi-fi already. Im addition, T-Mobile One Plus users receive free Wi-Fi for the entire flight.

So if you happen to be traveling domestically today, make sure and utilize your 30 minutes of free Wi-Fi.
