And many other features........
Now we'll explain one of the features which is the text messages.....
Definition: SMS stands for short message service. SMS is also often referred to as texting, sending text messages or text messaging. The service allows for short text messages to be sent from one cell phone to another cell phone or from the Web to another cell phone.

FINALLY!!!! I brought a video about the mobile phones...... but keep in mind that this video is talking about an experiment that was done by one of the people, hope you will enjoy it :D
This life in't only work , or doing the duties that you are asked to do . Sometime you need to have rest , to recreat or to entertain yourself.
For an example , you are goin on a long trip , and your picking up your MP3 player and your mobile videos devices. Are you going to spend all your time sleeping , or just watching ????
NoOOOOOOOoooo!!! So you'll directly go to your entertainment devices.
Therefore , what are entertainment devices?????
Entertainment Devices are those devices which are used to amuse the person in his free time , or whenever he is bored , like : MP3 players , DVDs etc.....
But do you think the inventors of these devices wanted the people to use these devices all the time ???
Let's see the advantages of these devices and the disadvantages to answer the above question ........Advantages of entertainment devices:
1- Instead of making a compact disc with a maximum of 21 music tracks, many companies redesigned their discmans to play raw mp3 files.
2- These MP3 players don't take much space as their size is like your finger size.It can easily fit into their pockets and they can take them anywhere they want.
3- Other than mobile music devices, there are many mobile video devices as well. These gadgets allow you to take your favorite videos with you wherever you go Also.
4- These devices have output features that allow you to hook up your device to television sets.
Now let's see the disadvantages:
1-mp3 player's headphones or earphone contain peices of magnet. When the music you're playing, release an ultrasonic tone, that bounces to your ear drums. Which is very dangerous.
2- You won't be social at all as you are spending all your times on these devices.
3- Your eyes will be affected due to the spending hours on the DVDs.
4- The price of the DVD Player is a lot.
5- It wastes a lot of your electricity due to which your bill is high
So , finally you don't have to spend all your time on technology as it ' ll affect you and won't be useful , just balance to have fun in your life too.
