True - they work by using microwave radiation.
Telephone, as in land lines. Cellular phones use electromagnetic radiation.
Mobile phones use electromagnetic radiation in the microwave range. However, specifically 02 mobile phones would have to be researched in order to determine exactly what kind of phone it was and what tower it associated with if any.

The most common exposure to electromagnetic radiation is from the use of cell phones. It is a minor almost minute exposure. Why it can damage the cell structure of humans is because it is toxic it is simply because it is radiation.
The transmitter circuit produces the radiation, which exits the phone primarily through the antenna. Due to some major concerns about constant exposure to the radiation from mobile phones -- which can and does approach two watts under some conditions -- many newer phones have the antenna at the bottom of the phone, rather than above the earpiece as in older phones.
