Hi,
As an old fashion, and because of the huge amount of rumors spread out about the waves that the cellular phone, I'm trying to avoid being close to it as much as i can. But i was enforced to use it these days as an alarm to wake me up.

my important question is ( although it may seem silly for somebody here): I'm using the cellular phone without SIM or GSM chip. Is it still trans/ceiving the same amount of signal or not.
