Does BiM Active use my minutes or my data plan while recording?
No, that would be a huge phone bill! Instead, the phone briefly accesses the network at the start of an activity to determine position and is off-network for the entire recording. Uploading your activity data to the BiM Active web site requires another brief network access. In practice, this equates to about 2-3 minutes of air-time per uploaded activity (20-30k of data).
