T-Mobile offers free text messaging. It allows its customers to send free text or picture messages during flights that have Gogo as their Wi-Fi connection.
T-Mobile also allows its customers to access its Visual Voice Mail for free during such flights. Gogo is a company that is specialized in in-flight connectivity technology. Some American airlines such as American Airlines and US Airways use Gogo for their Wi-Fi connection. T-Mobile customers can send free texts or picture messages while traveling in any of these airlines' planes, even when the plane is at a high altitude of 35,000 feet. However, the cell phones that they use must be compatible with Gogo. Recent models of Gogo-compatible cell phones are Apple iPhone 6, LG G3 and Nokia Lumia 635.
