Bit of a trivial problem (I hope!) but I'm a bit rubbish with technology so would really apreciate some help please!
Basically yesterday my phone (a Samsung U900) just came up with "limited service" and now I can't send/receive texts/phonecalls. It's definately a problem with the sim as I have tried it in two of my other phones and it still says the same "limited service" on the screen. However, I still have all the texts and numbers that were saved to my sim so I know that it can't be completely broken.
I don't know what to do! I'm a bit dependent on my phone being at Uni and whatnot and it's making me panic lol.
I can't ring up Orange because I have no phone to do so!
Does anyone have any ideas as to what could be up?
