The Internet is not the only high-tech tool that students have at their disposal. Cell phones are extremely popular with teenagers; pagers are perhaps less so. Some school districts do allow students to carry pagers for exceptional reasons, such as a medical condition that might require the student to contact help immediately. For general use, however, cell phones and paging devices are as distracting in a school building as they are everywhere else. Most schools have rules against bringing cell phones or pagers onto school property.
