Hi, I have just started getting a problem with my Desire where I keep getting a notification that I have no SIM card installed and I have to reboot the phone to get back to normal. At first I couldn't pin it down to any specific cause but now I have realised that it does it after coming out of Airplane mode. I am looking out to see if it happens at any other time. As I have it on Airplane mode every night and sometimes during the day, this is getting annoying. I have tried reseating the SIM card but it's still happening. Does anyone have any ideas please?
