When I turned to HTC G7 for help, I found that sim card applications consumed the most traffic. What is this swelling?

In order not to waste traffic and electricity, please make the following settings, which can play a certain role.

1 Settings-Wireless Network-Mobile Network Settings If you don't use 3G mode, choosing GSM only saves power than 3G mode.

2 Settings-Account and Synchronization-Turn off the background data (turning this on when using is the chief culprit of sneaking traffic and wasting electricity)

3 Settings-Location-When not in use, the GPS is turned off and the mobile phone is turned off.

4 Settings-Date and Time-Auto Delete

When updating and canceling timing synchronization and sound effects, the weather on the desktop is turned off and on.

It depends. You have done all the basic settings above. The application of SIM card is mobile phone, but most people don't. Can't you see this application or something? Can be viewed in the application. See if you can cancel or consult mobile customer service to cancel.

UC browser, you need to cancel the loading of pictures, otherwise the pictures are equivalent to the traffic of several web pages.
