Xperia GO JB Can't connect to Data.

Hi,

I updated my Xperia Go to Jelly Bean and when I connect to Data my SIM card is suddenly not recognized and I lose the service. Does anyone else have this problem?

That was pretty weird,

Have you tried another SIM-card? Another network provider? Any difference?

Try removing the proxy settings on your APN.

Settings > More.. > Mobile network > Access Point Names

Tap your internet account, usually called "[operator] Internet" or similar. Delete everything under Proxy and (Proxy) port.Save and try again.

Any difference?
