Hi I have unlocked and flashed my Samsung F480 but for some reason I cannot make or receive calls.
Everytime I make a call everythings going ok the it comes up diverting active then it say call rejected??
I have tried going into the call divert menu and cancel all diverts just in case but that come up with rejected by network??
I have no idea whats going on with it. I have checked the top righthand corner to see if there is a phone there with a red line though it but theres not.
I have a full signal but no way of making calls.
Any help and advice would be great.
Thanks
Rod
