To properly use the smrtPhone mobile app, you must enable access to the microphone (so your contacts can hear you!) Most of our users also prefer to have notifications on, so they know when a call or text comes in. It's up to you whether to enable Mobile Data, but if you plan to use smrtPhone away from WiFi, it is required.
This (silent) video will give you the visuals on the steps outlined below.
