The Nokia 6230 and the 6230i are both great mobile phones still today but some users may experience no network coverage or the message that says no network access when you search for your network provider manually.
1)Change the sim with a different network provider in case it is your sim card that is faulty and not your handset.If the sim card works in a different mobile phone it clearly shows that the Nokia 6230/i is the problem.
3)Change your mobile antenna.If you have dropped your Nokia in water or on the ground it is most likely your mobile antenna/aerial has got damaged.So try replacing it with a brand new replacement and see if you get any signal.

2)Update the firmware version to a latest version can also fix the no signal problem.There is a strong possibility that your software has a bug in it that is causing your phone to not find a network provider so its best to update first.
NOTE:You can't flash the 6230/i with a usb cable with just using jaf.
