I've just made three attempts to activate my micro sim in 72 hours. Each time I go through the registration process, nothing happens so I call back and they tell me I am not registered. I've just finished making my third attempt so HOPEFULLY this will finally work. If it does, no one has mentioned to me what the APN settings are. I really don't want to call back, I can't bare speaking to them again. The man at apple said it might either be 3internet or three.co.uk but he wasn't sure. Is there any username or password?
