You cannot change a phone's frequency.
it has something to do with certain radiation from the phone.
i was looking for a pictuer of a jig to make for a hold a cell phone to measure radiation
alcohol and cell phone radiation
The basic concept of the very first cell phone was developed in 1947. When the first cell phone came out in 1968, it only had a frequency range of a few miles.
no. infections are caused by bacteria or virus, not radiation
Radio waves have the longest wavelength and the lowest frequency among all types of electromagnetic waves. They are used in communication and are emitted by sources like radio stations and cell phones.
The frequency of the phone would depend on the model and the carrier or service provider it runs on. It would not depend on the phone number.
To a human being cell phone radiation is harmless. use of a cell phone is equivalent to a nominal amount of time in the sun. A live radio tower however could be extremely dangerous, do not climb over the safety fences or on the tower itself.
i have seen a video but i don't relive it so i said no but there is enough radiation to cause cancer in a phone.
