EVS was designed from the ground up to work with packet-switched services such as VoLTE (Voice over LTE). Fraunhofer calls it Full-HD Voice. The EVS codec allows bit rates ranging from 5.9 Kbit/s to 128 Kbit/s, which allows phone service providers to optimize their networks as needed.
You have much more control of EVs than IVs, but there are limitations upon them. Most notably, Pokemon are limited to 252 EVs (in this generation) per stat, and 510 EVs across all six. The limit per stat used to be 255, but was changed to 252 in this generation. A 255-EV Pokemon that gets Transported will have its EV reduced to 252.
