How to solve the problem of MOTO A3000 automatically connecting to GPRS?

None of these answers have used A3000!

When your A3000 just accepted a MMS message or surfed the Internet, and your phone has not done anything now, it The status of the wireless manager is: (GPRS) (EDGE), which is normal. Simply put, this is just an indication of your network status.

You only need to disconnect. It is okay not to disconnect, even if You have been connected for 100 hours, but you are not using it! As long as you are not online for that much time! (That is, there is actual traffic generated)

Also, there is no way to change this phenomenon of A3000. It's just an indication of network status, don't worry...
