ok so i got my san fransisco from argos today, got home put the sim in and it said no service, so then i thought well dont need the orange sim so unlocked it and put my pay monthly o2 sim in, still no service. Just phoned up orange cust services didnt mention that id unlocked it, and he said "oh your orange sim hasnt been activated so ill activate it now". My question is shouldnt my O2 sim still have worked and is it a problem with the phone? or does it need to be activated with an orange sim before you can unlock it?
PS still no signal but can take up to 24hrs apparently
