Most teenagers have cell phones so that they can talk and text their friends. If you have a teen with a cell phone, you should be sure to purchase mobile phone insurance. The insurance will protect your teen's phone if it gets wet or damaged. It will also cover the cell phone if it is lost or stolen. The cost of the insurance is much cheaper than replacing a cellular phone, as many cell phones cost hundreds of dollars to replace. Most mobile phone insurance plans cost less than five dollars a month.
