Passing It On, Mobile Phone Etiquette

I received a newsletter from my cellular phone service provider today. I normally just automatically delete these but I was drawn to the article on mobile phone etiquette which I am sharing in my own words. Here are 6 major rules mentioned:
1. Avoid “cell yell”
I plead guilty as charged. Aside from the fact that my hearing is not great, I always feel the need to semi-shout into the handset in order to be heard by my sister in, lets say Manila, which is thousands of miles away. I know that with today's technology this should not be the case but it is a throwback to the times when all I would hear when I made an international call was static. I will make a conscious effort as suggested, to imagine that the person on the other end of the line is standing next to me the next time I am on the phone.
2. Be discreet
Just because you’re on your private phone, doesn’t mean your conversation is, well, private. Exercise prudence and self-restraint in speech. Cursing, arguing and personal details, like that tattoo you just got in an unmentionable place, should be saved for conversations behind closed doors. The person sitting beside you in the airport waiting lounge does not need to know the details of the merger you just made.
3. Save face with the people you’re with
When you are in the middle of a face-to-face conversation and your phone rings, never jump to answer it right away. More so when you are in the middle of doing business, or on a date. Not only is it rude, it sends a signal to the person to whom you’re talking, that he or she is less important than whoever might be on the other of the line. In other words: let it go to voicemail, there is a reason why it was invented.
4. Plan ahead
If you are expecting an important phone call, give those you are with ample warning. If you are in a room full of people, set your phone to vibrate even if you love your "Boom Boom Pow Pow" ringtone. Excuse yourself when it comes. It is not that complicated.
5. Think quick
There are times we simply forget to turn off our phones when we should. If it happens, act fast — hit silence and apologize. You can check who called later. Which brings me to the last rule......
6. Location, location, location
Shut off your phone at church unless you want the priest/pastor glaring at you. Do not even think of putting it on vibrate unless you are a doctor and you are expecting to be called on an emergency.

Any public venue (theater, play, or concert) where other people have paid for entertainment, not to hear you talk. When you are texting at the movie theater in the dark, the light from your cell phone still illuminates and is a distraction. If you have to, then step outside.

Restaurant - specially a fine-dining one where people pay a lot of money to enjoy their meal and have a good conversation with the company they are keeping.

Just think about it, keep in mind the golden rule.
