Text message issue and Mobile data issue

[duldula]

I'm afraid, I can't send text messages from my Xperia P. It happens, when I make a call and after that I can't send text messages. It shows only sending, I have to restart the device. More than 15 times already re-started today. It only happens after I make a call. USSD also not working since restart the phone. Also I'm having some issue with mobile data, When I turn on mobile data it won't connect to the network, but after re-start it's connect. Please help, Most of P users here have these issues.

Best regards.

It is firmware issue,there is no actual fix to the problem.The only thing that could help is a bug free update.
