T-Mobile is expanding its Simple Global international plan to 70 more countries starting on July 22nd, which will bring the total number of countries and destination served to 210. Introduced alongside the additional regions of coverage is T-Mobile’s new $5 daily data pass, which you can use for 512MB of 4G LTE data unlimited text and talk, starting on August 1st.

This move will establish T-Mobile’s Simple Global plan as the most widely available international data plan for US customers who are already subscribed to the T-Mobile One mobile plan with 25 cents / minute flat-rate calling.

Compared to AT&T and Verizon, T-Mobile has the most countries and destinations covered with the lowest cost for its international data pass. Now, the real test is traveling to each destination to see just how well the expanded service works.
