The Xiaomi Smart Kids Watch supports data roaming. However, due to variations in network frequency bands across different countries and regions, it cannot guarantee full functionality in all areas. Whether it works properly depends on the actual network conditions in the location where the device is being used.
Data roaming refers to the ability of a device to connect to networks outside its home carrier's coverage area, when traveling abroad. It allows you to access mobile data services like internet browsing, messaging, and GPS navigation through partner networks. While convenient, roaming relies on network compatibility and agreements between carriers. If the local network’s frequency bands are not supported by the watch, it can result in reduced functionality or no service at all.
Note:
For optimal use, it is recommended to check the device's network band compatibility and consult the local carrier before traveling.
