What happens if the phone signal is unavailable during a walk?
If the phone signal becomes unavailable, you may not be able to receive the most up-to-date tracking data from your tracker, nor send live tracking commands to it.
However, the Pawfit tracks all the time even when there is no phone signal. It stores the offline tracking data and sends this data over when it gets a phone signal again. Once it gets a phone signal again, it sends over all the offline data so you would know where your pet has been. You can check the historical tracking data on the Activity and History screen.
