Has anyone experienced the use of a pager? We want our kids to be able to contact us in emergency only. We have had cell phones and do not use them for chatting. Want the ability to be reached in all areas without the high cost of a phone that will never be used plus the two year contract. We do have our old cell phone programmed for 911 if needed. We will check in with family weekly via pay phone or internet at libraries. Any ideas?
