What should I do if I can't make a video call on Xiaomi Smart Kids Watch?

The watch must be in 4G or WiFi network environment to make video call; if the watch is in 2G network, please switch to 4G network or connect to WiFi network and try again.
When the power of the watch is lower than 20%, in order to ensure the normal voice call and positioning needs, so the watch pause can not initiate and receive video call requests to reduce the loss of power, please charge the watch in time to make normal video calls.
