Having a way for people to contact you is critical for success in your information and intelligence gathering efforts. If your agency doesn’t provide you with a department issued phone, a simple and safe way to keep in contact with street sources is to buy a cheap pre-paid cellphone. These phones are also commonly known as throw away phones. You buy a certain amount of minutes and pay as you go when you need additional minutes.
Giving this phone number out to people on the street gives them an easy and cheap way to contact you. It also avoids you having to give out your personal cell number.
