More and more information is coming out on the negative effects from cell phone radiation. There are many studies out there that suggest that cell phones cause brain tumors and brain cancer. I believe that everyone should protect themselves by adding a very inexpensive cell phone chip to their cell phones. And parents who are letting their teenagers and younger children use cell phones this is an absolute must. I use a cell phone chip on my cell phone and I have for years. For more information on the cell phone chip that I use please contact me at the office 972-434-7780.
