Not sure if this question has already been asked but I have a Samsung Galaxy S2 mobile phone I am able to make outgoing calls and send texts but I am unable to receive texts and phone calls. When I dial my number from another phone it makes a dead line sound. I have tried changing the Sim to another phone & dusting the Sim down.

Does anyone know how I can fix this or what could be wrong with it?

You are on O2?

Yes I'm with 02 just seen they are having problems with the signal hopefully it will be sorted soon. Thanks for the reply
