I faced the same problem with my Samsung Ace S5830 that it keeps losing the network signal. I formatted the phone and still the same problem. I took the phone to the Samsung store and they opened the phone and cleaned it with some solution and i tried to use the phone for sometime and still the same. I was very frustrated with and unhappy with my phone as it is not even a month and it kept on losing the signal and sometimes would restart and would lose the battery charge. I tried doing this step( Settings>Wireless and Networks>Mobile Networks>Network Mode>Select either GSM or CDMA(Depends on the provider) By default, it would be selected as GSM/WCDMA(Auto Mode)
From Network Operators select the desired network and then restart the phone. Hope this would fix the problem.

FIRST RESOLD NETWORK IS THEN CHANGE NETWORK IC.

1.There might be temporary network congestion from the service provider end .......Check in different area and handset ......If there is no problem when tried in different handset ...

2.Install Blackberry desktop Manager ...Take Backup..
Reinstall the Software ....
3.if still not happening contact service center as there might be any hardware problem.

Sounds like your phone is stuck in flight mode for some reason. Have you tried a Master Reset (you will lose all your personal data if you do this).
