Good evening. I am still getting used to my new Android ZTE Maven. This phone keeps on notifying me about Wi-Fi calling. While I understand the pros of enabling this feature, and have some idea of the cons. I am hoping to find out the easy way (by posting this question) whether or not my specific device is able to take advantage of Wi-Fi calling, and if so, is there any pitfalls (other than the storage space eaten up by the app)?
