As experienced phone users we all know that phone numbers can give you information about the person who is using it. If it is a mobile number then the first digits of the number can usually tell you what network that person belongs to.
If it is a landline number then you can tell what area they are phoning from and if it is from overseas you can even tell what country they are phoning from. Numbers are all around us and we gain information from them without even realising it.
How often do you look at your mobile phone and see a number which you immediately associate with a particular person. You also know that if you use any of the 0800 numbers that your phone call will be free.
With the wonders of modern communication technology we are able to keep in contact with people all over the world. A few decades ago you would have to book a time with the operator, and both parties would have to be there at precisely the right moment.
Now you can reach anyone in the world no matter what time it is. They may not appreciate being woken in the middle of the night but at least you have the option to if it is necessary. It really is a wonder we take for granted.
