Mobile phones are useful tools
Mobile phones are poised to become a dominant Internet platform outside the home. The reverse phone look up is becoming the storehouses of our digital lives, containing a growing share of our personal and professional resources and data. Mobile phones are low power radio devices that transmit and receive radio frequency radiation (at frequencies in the microwave range of 900-1800 MHz) through an antenna used close to the user’s head. Mobile phones are not as restrained by illiteracy as one would think. The worst problem seems to be that conversations on mobile phones are more noticeable than face-to-face conversations. Mobile phones are very useful tools for informal learning.
