The Galaxy S5 Active for AT&T in the US is said to carry model number SM - G870A, so it's possible we could be looking at the international model of the device, even though Samsung doesn't change the numbering in the model numbers anymore even if the handsets are for particular carriers.

Samsung explained recently that this is because the carrier - locked models only have to go through testing for one particular carrier only whereas the unlocked models need to be put through rigorous testing for all supported networks to ensure proper network functionality. (sammobile.com)
Be certain when looking at particular carriers that you find options that are easy to wear and will not be too difficult to utilize as you are aiming to transport your kids to and from different places of interest. (babycarrierhq.com)
