The desktop of HTC mobile phone shows the weather. How is this function realized? Is there a charge, a monthly fee or a function fee?

Don't listen to the upstairs. No charge. Next time it's inked, put it in your mobile phone, not on the SD card. Then press and hold the screen to add the weather in ink in the widget, and you can automatically update the weather after setting the city.

Will it be updated automatically without opening the network connection? This is a bit strange, isn't it? I didn't bring mine. The usage traffic is actually very small.
