Most cell phone networks allow you to block your cell phone number when making outgoing calls. Some phones have a "block number" option, while other phones require you to ask a customer service representative to block your number. For the most part, blocking your number does not affect text messages. A text message from any cell phone displays the sender's number, even if that sender has blocked her number. However, you can send text messages with a blocked number over the Internet.
