The DTMF (Dual-Tone Multi-Frequency) setting on a cell phone typically refers to the length of the tones produced when dialing a number. The choice between long, short, or off depends on personal preference and the specific requirements of the user. Long tones may be preferable for individuals who need auditory feedback, while short tones can help expedite the dialing process. Turning the DTMF off can be useful in environments where noise interference may disrupt the tone recognition.
Yep.
it is not recommended to use your cell phone when charging, this could cause the circuits to short. Ideally you should charge your battery when your phone is turned off
yes
Go to your local phone service store in your town. Ask them if you can get a cell phone card for your cell phone. They should be able to answer your question.
i think that you should be at least over 16 to get a cell phone
Yes. A 12 year old should have a cell phone. They should be mature enough to handle a cell phone. My daughter's are triplets and they are all very responsible about what they do on there phone. I think that 12 year old's should have a phone.
You should be over eighteen yaers old and should have a job so that your can pay for your cell phone.
not unless you are into a phone a month
No.
you should call your cell from your house phone or a friends phone.
I think eleven or twelve is a good age for a cell phone.
