On October 9, 2013, T-Mobile announced Simple Global, a service included with eligible Simple Choice plans. This service allows one to roam in over 100 countries with unlimited text and speed-limited data, and make calls at $0.20/minute. High-speed data passes will be available for purchase. On March 7, 2014, T-Mobile announced this number will be increasing to 122 countries. If one is connected to WiFi in one of these countries, and their phone supports WiFi calling, all calls and texts to and from the USA are free, and work the same as if they were on the cellular network.
