I got my sony ericsson c903 phone a couple of weeks ago on the 3 mobile network.
The alarm worked this morning, but then when I turned it on, i had a message saying "insert USIM"
I tried turning it off and on, but they did nothing.
Then I took the battery out and the sim out, then put it back in and turned it on, but that did nothing.
The message then went away so I can see my wallpaper.
And I can access my pictures, the camera, files and messages and everything.
But it says there's no network coverage when Im at places where its been fine before.
And I can't recieve or send calls or texts or go on the internet.
How do I get it back to working properly?!
Thanks.
