Cell phones make it simple for us to maintain regular contact with our family and friends. The devices available nowadays, permit you to do other things than just talk. You could use them to send pictures, texts, e-mails and videos. Nowadays, mobile phones can also be used as walkie-talkies.

Initially, mobile phones couldn’t be taken with you all the time because they were huge and bulky and in some cases, had to be joined to a base. They were also very costly. The initial devices had partial reception because mobile phone towers were not as much in number as they are nowadays. As time elapsed, the devices turned more and more superior and reception enhanced to a great extent.
