According to a document leaked to Tmo News T-Mobile will launch a new add one for customers on a T-Mobile ONE plan called ‘Global Plus’. For $50 a month users will receive:

Unlimited high-speed data while roaming in a Simple Global country

5GB high-speed, international tethering in a Simple Global country

Unlimited Simple Global to Simple Global calling at $0.00 per minute

Unlimited messaging

Unlimited stateside international talk and text

All features of the ONE PLUS international add on.

Previously you could pay $5 daily to get high speed data and calling. It looks like the plan needs to be in place for a full billing cycle, but it isn’t clear if the add on can be added and removed at will. If you were already using the $5 daily add on more than 10 times a month then you’d be coming out ahead on the new plan.
