1. How does wireless phone service work?
Similar to how a cordless phone works with its base in your kitchen or bedroom, wireless phones receive and transmit messages using low-power radio transmitters located in your community. Each transmitter serves a geographic area called a cell. Equipment within each cell relays your message to a mobile telephone switching office, which in turn sends the message to the local landline telephone system to complete your connection. As you travel from cell to cell, your calls are transferred to you without interruption.

2. What is the difference between analog and digital?
Wireless calls can be transmitted using either digital or analog technology. Analog technology transmits your voice over airwaves to cellular antennas, much like a radio broadcast. Digital technology converts your voice into groups of electronic bits that are "reassembled" into your voice when they reach their destination. Digital transmission allows for greater voice clarity, privacy, advanced telephone features and more capacity.

3. How can I protect myself from wireless phone fraud?
Wireless phone fraud is the unauthorized use of a wireless telephone network with the intention of getting free service. This kind of fraud is a costly crime in the wireless industry. To help protect yourself from wireless phone fraud, please: Lock your wireless phone (with a PIN code) when not in use. Immediately report a lost or stolen phone carrier. Look for any unusual activity on your bill. Report frequent wrong-number calls or hang-ups. Here are additional tips to help protect yourself from subscription fraud: Only give out your social security number when absolutely necessary. Do not carry extra credit cards, your social security card, birth certificate or passport in your purse or wallet, except when necessary. Shred or rip up preapproved credit applications before throwing them away. Do the same with bank statements, phone bills and credit card receipts. Have your name removed from promotional lists operated by credit reporting bureaus and those who extend credit. Keep your wireless service agreement in a safe place.
