Sony Ericsson NAITE J105i is completely slow!!!

[#1]

My phone Sony Ericsson NAITE J105i is completely slow!!

It takes almost 3 minutes to send a text message either from conversation application or write message.
And while sending SMS if an incoming call is encountered the phone completely gets stuck up for 5+ minutes..
No action is performed even if the buttons are pressed!!!

I'm really fed up with this phone; Nokia is best particularly with this issue 😞

First check that you don't have a lot of messages in your sent/inbox and that your phone has the correct time and date.Otherwise, try running the SE update service on your phone and see if that solves the problem.Failing that, it could be a network issue.
