For Cell Phones too. A reminder. On 11/10/05, cell phone numbers will be released to telemarketing companies and you will begin receiving sales calls. Those incoming calls will be billed against your account the same as any other incoming call. You can register your cell phone number on the DO NOT CALL list, just like you did your land line home phone. I recommend you do it on line: https://www.donotcall.gov/default.aspx If you don't remember whether or not you've already registered, you can use that web site to check. Registration is good for 5 years. Or you can call 1-888-382-1222; however you MUST be calling from the phone you want to add to the National DO NOT CALL list.
