It is clear that mobile 
phones
 have bought many advantages in 
people
’s lives because of their convenience. Mobile 
phones
 are not only a very useful communication tool they 
also
 serve many other purposes including storing information, providing learning tools and entertainment. 
However
, mobile 
phones
 need to be used appropriately 
otherwise
 they can become intrusive. In 
this
 essay,the importance of mobile 
phones
 will be discussed.
The original purpose of mobile 
phones
 was to offer 
people
 a convenient communication tool that allows them to be contactable wherever they are and aids communication. An important consequence of the ability to contact 
people
 is that mobile 
phones
 can 
also
 act as safety devices and are routinely given to children for safety reasons and 
also
 give a level of comfort to women who are out late at night.
However
, the modern mobile 
phone
 or Smartphone has developed far beyond its original purpose and has many advantages. 
Phones
 are commonly used for entertainment and allow society to listen to music when they are performing other activities 
such
 as travelling on public transport, exercising or waiting for others. Mobile 
phones
 also
 play an important role in 
people
’s work lives and allow them to access e-mail and calendars irrespective of whether they are in the office or not. A 
further
 important feature of mobile 
phones
 is that they have the ability to run sophisticated software that can be used for learning. 
For example
, language learners often have dictionaries, flashcard and other language learning applications on their 
phone
. An important aspect of mobile 
phone
 usage is that they allow 
people
 to be entertained, to work or to learn when they have an hour that they could not previously use for productive purposes 
such
 as when they are waiting or travelling.
Although
 it is difficult to argue that mobile 
phones
 are not powerful and useful tools, it is important that they are used wisely. Being accessible means that 
people
 can be interrupted at any point in time and 
phones
 can become intrusive. 
For example
, it is important that 
people
 have time away from the work environment but a mobile 
phone
 may mean that they can be contacted at any time of the day or night. 
In addition
, mobile 
phones
 may cause 
people
 to become anti-social and focus on 
phones
 rather than the 
people
 that they are with. 
Furthermore
, 
phones
 can be distracting and unsafe if 
people
 are focusing on their 
phone
 rather than their surroundings.
In summary, mobile 
phones
 are an extraordinarily useful tool but it is important that 
people
 use them wisely and ensure that they have a private moment, interact with other 
people
 and remain safe at all times.
