So as someone noted above, Sprint is now copying T-Mobile with free throttled data in a lot of countries.

But one wrinkle is that you can buy a "high-speed data pass" by the day or week which apparently has no data limits.
So $5 per day in most countries outside of North America or $25 a week. Wish T-Mobile offered this option. They offer high speed data pass but it's more expensive and the data limits are a couple of hundred megabytes.
Wonder how Sprint's international roaming partners compares to T-Mobile's.
Wonder if Sprint offers Wifi calling.
