Hi,
You can use a mobile shield which cuts down the EMF emitted from the mobile and may be useful in your case!
You know, I actually have a friend that has the same condition. She is also very sensitive to electronics as well, such as the TV, radio, etc. For now, I don't know if there is any cure, it's just something she has to deal with unfortunately. I wish I could help you out more.
