LTE frequencies are an issue mostly for those outside the Americas since most phones sold North and South are the US/American versions and thus have at least one of the bands used in the U.S. This is specially true for higher end phones like Samsung's Galaxy S and Note and even more so for the Iphone. Also, the newer a phone is the more LTE bands it will support. As usual, always check first.

Voltage is not an issue for those in most of the Americas, Japan and Taiwan since these countries have 110 volt type systems and use the same plug. China, despite being a 220 volt country uses a similar plug for smaller appliances and thus most visitors from there won't need adapters to charge their devices. As stated in the article, almost all chargers work on both voltages but, again, always check first. It should say 100-240 V 50-60 Hz on the charger or appliance itself.
