我有Karbonn A9，Android 2.3.6。 GPRS / DATA偶尔不会打开，但是一旦我重新启动手机，我就可以启动它。 在停用GPRS /数据后，我必须重新启动手机获取数据或GPRS再次连接。什么可能导致这个？
I have Karbonn A9, Android 2.3.6. The GPRS/Data does not switch on occasionally, but once I reboot the phone I can start it. After deactivating GPRS/Data I have to reboot the phone get either data or GPRS to connect again. What could be causing this?
Backup your data and factory reset your device. If problem is intact, its firmware issue. Fixing it isn't easier than flashing new ROM.
The best way to work around: Disconnect Mobile Data by renaming APN. No need to factory reset or to flash new ROM. You don't need to rename APN manually. Install Widgetsoid and use its mobile data toggle widget. In settings, make sure toggle method is APN renaming. Done!
