Does the the nCommand app use my cell minutes?

The answer to this question depends on your configuration however if properly configured, nCommand does not use your cellular voice minutes, it does, however, use data. When nCommand communicates with cloudUC servers, it can use either cellular data or wifi data, depending on which is available. If you plan to use nCommand heavily, ensure that your cellular plan includes an adequate data plan to accommodate the additional data consumed by the application. Typically voice calls use very little bandwidth, less than 200kbps bidirectionally, but over time, this can add up. It is recommended that you use wifi whenever possible to minimize cellular data plan consumption.
