Samsung unveiled new Pink Gold options for the Galaxy S7 and Galaxy S7 edge a few days ago. The two new flavors are available for purchase in South Korea, but Samsung promised other "select" markets to get them soon.
The first of those markets will be the Netherlands. T-Mobile will be offering both Galaxy S7 and Galaxy S7 edge in Pink Gold on June 23. You can pre-order them now, and you will receive a free 64GB microSD card.
There is no info if this color will be a T-Mobile exclusive for the Netherlands but it's highly unlikely. The other carriers should be offering the Pink Gold models, too.
We'll keep you in the loop for when we learn more about those "select" markets.
