> No, they can't be connected to AT&T, Verizon, or T-Mobile in the US. T-Mobile still has a 2G network operating in most of the country and the 5S supports voLTE so it can use both 2G and LTE for calls. It does not have any low band support, so indoor and rural coverage will suck, but it will work. Even if it didn't have voLTE it would still work on T-Mobile on LTE data and if you were in a GSM market it would fall back to 2G to make calls. The stores won't activate it, but you can take an activated sim card and pop it in and they will not blacklist it. T-Mobile technically still has 3G broadcasting on their femtocells so that's another option for calls/data if you're around them.
