Terrible Audio Quality Vs. FaceTime Audio! – FreedomPop: Calling & Texting Review

Terrible Audio Quality Vs. FaceTime Audio! Tested on both iPhone 5s & iPad Mini 4 w/Cellular. Must be a low quality/bandwidth codec, plus you have to use the VoIP app on iPhone 5s, cannot use the native phone app. ? Good costs, however.
