If your child's calls end on their own, a few things could be behind it. Work through these, most common first. A couple differ by model.
Common reasons
Weak cell signal
Check the current signal strength by pressing the top side button and swiping down from the top of the screen, and move to a spot with better reception. The watch does not support Wi-Fi calling, so it needs a cellular signal.The 30-minute call limit
On the Bark Watch plan, calls end automatically after 30 minutes to help manage usage. This is expected, not a malfunction. Your child can simply call back to keep talking.
āLow battery
If the battery gets very low, the watch may end the call. On the Samsung model, once the battery hits 1%, the watch switches to Watch Only mode and cannot take calls until it charges. Charge the watch and try again.
āRestart the watch.
A quick restart clears many temporary issues.
āSamsung model: press and hold the Home button and the Back button for about 7 seconds.
āSchok model: press and hold the top side button for about 20 seconds.
