Ok, if you prefer Wi-Fi, there is also no point whatsoever to use 3G for calls too.
Use GSM, which is at a lower frequency, less radiation emitted thus you brains and ears will last much longer.
How to disable 3G data internet:
1) Switch you phone to offline mode, then go under 'settings' > 'connectivity', then enter 'DESTINATIONS'.
2) Click on 'Internet'. Then use the options button to delete the access point of your mobile provider. Then, revert back from 'Offline mode' to 'General', in order to use your phone.
3) You can either remain using 3G for calls or if you wish to change to GSM, then under 'Connnectivity'. click 'Network' on top and under 'Network Mode', change to 'GSM'.
By performing steps (1) and (2), there will no longer be any more data internet using mobile provider.

P.S. Afer you delete the access point of your phone provider, they will send you a few sms asking you to install back the access point.
Throw away the installation sms and after a few attempts, they will not pester you again.
