• The person in front of you takes precedence to the person calling you (who you may or may not know).
• You should always respect the person in front of you, and not let them think the person on the phone is more interesting or important (even if they are!).
• You shouldn't use your phone when you’re having a one-on-one conversation with people, or in most public places.

DO NOT USE YOUR MOBILE IN:
Restaurants
Hospitals
Shops
During a conversation
Public places like hairdressers, churches, conferences

If you have to take the call
Your ringtone represents you, do you want people to think you are a nightclubbing fiend, or a professional? It’s best to stick to a respectable ringtone, preferably “ring, ring”. If you must answer your phone, say, “I’m sorry, do you mind if I answer this call?”. Keep the phone call short, and let the person know what time you’ll call them back.

TEXT MESSAGE ETIQUETTE:
Never break up by text
Don’t cancel on someone by text
Do not call in sick to work via text
A phone call is always more personal than SMS

What texting is good for?
Texting is good for confirming social engagements, or sending someone brief information such as an address or phone number. Your phone is not an essential accessory. Leave it at home when you don't need it.
