Did you try to switch on and off Airplane mode and then turn back on Data mode? Maybe there is some glitch with your network connection?

Internet settings are not downloaded via wifi,are downloaded via mobile network.But I think you should repair via sony update service:

Still the same only wifi will re activate..

first be sure there is not any network problem(may be its down for maintance or etc)

try active and deactive airplane mode..be sure wi-fi s off..and sometimes it take times to data goes on.

There is no down of the network because i can send text messages..
