How to enable mobile network in Android Tablet I have got Karbonn Ta-Fone A34 tablet. By default its mobile network options is permanently inactive. 
Now I have rooted my tablet and want to enable to mobile network option. 
Is there any way I can browse the Android System files and make changes there to enable the mobile network or if there is any app to do this.
According to the specs you linked, this tablet doesn't support 3G mobile networks, only GSM. To enable the mobile network features, you need to buy a 3G USB dongle and connect it to the tablet.
