Check that the network mode is set on WCDMA/GSM or only WCDMA. 

Make sure that you have data enabled if it's Internet you have problem with. 

Try downloading new Internet settings from settings > Xperia > Internet settings. If you still have a problem I suggest that you try with another SIM card in your phone.
