stixLFC hello,

Try to manually define the network by going to Main menu - Settings - Connectivity - Cellular networks - Search Mode - Manual - there, choose the right network.

I think what you have to consider for it to work is your phones GPRS settings, try to check it and if you don't have it yet, ask for it from your network provider my phone works with GPRS I hope I had helped you....gud luck!

you may have to reinstall the O.S of the Phone.
They call it upgrading the Firmware and that will fix the issue!
And don't delete any files which are hidden under the folder " System"
That causes this issue
do not alter some files in the phone and it ll not allow u to use any applications and games apart from walkman and the Internet browser!
hope this helps...


good luck:-)
