Only if you believe they are reliable enough.
It is impossible
A cell phone does not have a busy signal. If the person is on the phone, the call would go to voicemail, or it would go to call waiting.
You won't. Contact the police.
That means that the person you are trying to call has a pre paid phone and he/she does not have enough balance to receive calls. - http://www.myspace.com/4cfedh22
No your phone is off
If a person's cell phone is off, police typically cannot track its location using standard methods because the device is not sending out signals. However, if the phone was recently on, police may be able to access its last known location through the carrier, such as Verizon. Additionally, if there are ongoing investigations or if a person is deemed in danger, law enforcement may seek a court order to obtain location data from the carrier.
Yes, but the text will still get received by the other person.
By switching your phone off at certain times, there might be an urgency and a person tries to contact you. If you are off, the person is likely to get hurt because of your absence.
Your phone will not be sticky, I peeled mine off
They will tell you when the plane takes off to turn off the phone.
