Pagers as a way to be notified and avoid EMF from Cellular Phones.
More and more people are becoming educated to the danger of radiation and electro magnetic fields.
What does EMF do to your body?
According to the World Health Organization...The main effect of radiofrequency electromagnetic fields is heating of body tissues. There is no doubt that short-term exposure to very high levels of electromagnetic fields can be harmful to health.
While the debate is on regarding if cellphones are dangerous or not to your health...More and more people are being diagnosed with cancer, especially tumors near the ear, brain, breasts and thyroid, more and more studies draw a correlation between a higher percentage of cellphone usage and the effects of EMF radiation over the long term.

Is it practical to think that the world can function without cell phones? Of course not, but why not use cell phones via blue tooth speakers when possible and not hold the phone close to your head or body.
A 1-way pager does not transmit and therefore can receive a message and then you can determine how and when you will make a return call.
Using a pager in combination with your cell phone could be the short term solution to a long term problem.
