I am well aware of the importance of the
PDA phone in a person's life. This is one of the
hi-tech portable phones that can help you organize your daily schedules, meetings, and a lot more. However, there are some times when you have to follow some PDA
phone etiquettes depending on the situation. If not, then you might look like a rude person infront of other people.
When you are in a business meeting, it is proper to shut off your phone so that it will not cause a disturbance. In any case you are waiting for a very important reply; just use its silent function. However, do not check your phone every second or minute. The individual who is talking at that moment will feel insulted and will think that you are bored with what he or she is saying. Your action may cause him or her to ask you to leave the room. I'm sure that you do not want that embarrassing moment to happen to you.
You can also prevent this from happening by telling the group beforehand that you are waiting for a very important call or text message. Emphasize that it is a life and death situation and you really have to take that call or message. I'm pretty sure they would understand your situation and will not bother you when you check your phone from time to time.
