With the increasing use of cell phones, spam message has become a heated issue. According to a survey, on average, people receive about 40 pieces of spam message per month. Spam message may disturb, confuse, or even threaten people at any time.

　　Generally, there are two reasons for the spam epidemic. On one hand, due to the fact that text message is a comparatively cheap channel, many companies take advantage of it to advertise their products or services. Whether people are willing to receive the message is neglected. On the other hand, operators holding lots of information on cell phone users sell the information and make money out of it.

　　To solve the problem of spam message, relative authorities and professionals should make joint efforts. The government should set up laws to severely punish the illegal advertisers and those who disclose users information. Cell phone researchers and developers should upgrade the products and enable them to delete the spam automatically. Should people act together, they will be free from the spam message.
