Cell phone bills can be long and detailed, but it’s important to read your bill each month so that you know what you are being charged and by whom. Some wireless phone providers will include charges from third parties for additional products or services, such as apps you may have purchased. Sometimes, however, those charges are unauthorized, in a practice known as “cramming.” These extra charges are often labeled “premium service” or something similar, and can be in amounts under $10, which are easily overlooked. These services might provide daily trivia or horoscopes information via text message. According to the Federal Trade Commission, many consumers report receiving a text message informing them of a subscription they never ordered.
