You cannot change a phone's frequency.
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.
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.
500 Mhz to 4Ghz
It cant be done, with todays cell phone networks, its not possible to transimit "radio frequency" over the phone like that.
It really depends on the cell phone company you have some don't let you change and some do. I would advise you to contact your local cell phone company.
Do edit, then retype the number.
yes. cell phone automatically change.
No. It might damage the phone, though.
Because quartz vibrates at a fixed frequency when an electrical current is applied (32,768 Hz) The quartz crystal keeps the phone's clock & calendar accurate, and also provides the 'base' frequency for phone-calls.
