Advantage and DisAdvantage of using CELL PHONE?  

any product has disadvantages. one should be careful in handling the product. A ship is made to travel in sea, but if we worthen ry that it will sink, then what is the purpose of the ship. There are more uses of a cell phone than disadvantages.

I think this is something we people should pay attention to, even when taking a flight we should not switch mobile on as it can create such a vibration which can blast the whole plane so better to avoid using mobiles in these places, There is also the filling station, as we also called the gas station where mobile is not allowed so places where it is indicated that mobile phones should not be used then we should avoid using them there.
