What are Frequency bands?

Phones communicate with mobile towers using radio waves, like how a television works. As our cities are flooded with waves from radio, television, wifi and other devices, governments strictly control the frequencies on which mobile phones are allowed to operate. These are known as frequency bands. If you wish to use your phone overseas, or with different carriers, it is important to ensure your device supports as many frequency bands as possible.
