Do you charge for the weather forecast on Android? When I took out my sim card, the weather was still there. What is the explanation?

Take out the SIM card and you can use it as usual. Does your mobile phone have WIFI? If there is, it may be a WIFI connection! ! If not, Dorsey, your mobile phone is amazing! ! ! ! ! ! Because there is only one way to update the weather forecast software of Android through the Internet! The charge is divided into GPRS /WCDMA3g/wifi! In addition to WIFI, you have to charge traffic money ~!
