T-Mobile 將要推出國際漫遊單一費率的資費方案：「T-Mobile to offer free unlimited international data, texts」。
T-Mobile's latest shake-up puts international roaming rates in its sights, with the carrier eliminating fees for data and text messages entirely in more than 100 countries. It will also simplify the calling rates, charging a fixed rate of 20 cents per minute.

不過 unlimited international data 是有速度限制的：
Chief Marketing Officer Mike Sievert said the average speed customers would get would be around 128 kilobits a second.
T-Mobile hopes to make some of its money back with "speed packs" that customers can purchase on the fly to boost their connection speed temporarily. For $15, a customer gets a single day's worth of high-speed data up to 100 megabytes, while $20 gets one week at 200 megabytes and $50 gets two weeks and 500 megabytes. The speeds are more accustomed to T-Mobile's HSPA+ networks, since international roaming with LTE isn't broadly available.
Only T-Mobile’s network can give you unlimited everything for everyone. Other carriers may even make you share minutes, messages, and data between you and your family. With the Simple Choice Plan, each line comes with unlimited talk, text, and data while on our home network—and starting October 20, unlimited data and text in over 100 countries at no extra charge. That means no overages just about anywhere you go. Plus, there's no annual service contract and it's easy to add additional lines.
