Starting June 21st, T-Mobile's most popular plans will include more and/or faster data while overseas, as well as inflight on major US airlines.
T-Mobile's most premium plan, Magenta Max, gets the biggest upgrades, with 5 GB of international high-speed data each month — up to 5G speeds where available — in 210+ countries and destinations. The same plan will also now include free inflight Wi-Fi, all flight long, on "select flights" with Delta, American, and Alaska, coming soon to United as well.
This includes streaming TV "where available". These same benefits also apply to the Business Unlimited Ultimate plan.
Customers on Magenta, Business Unlimited Advanced, and equivalent Sprint plans also see improvements, though not as great. For international roaming, those customers will now get 5 GB of 5G data each month in the 11 European countries with a T-Mobile network: Austria, Croatia, Czech Republic, Germany, Greece, Hungary, Macedonia, Montenegro, Poland, Romania, and Slovakia.
In other countries, the free data roaming speed (for things like basic navigation and email) is being doubled from 128 kbps to 256 kbps. For inflight Wi-Fi, Magenta customers will now get free service for the whole flight on up to four flights each year, and one free hour on all additional flights.
