Rules for Toll Free Numbers Cell Phones

Free to Call
Even though you will be calling the toll-free number from your cell phone, you will not be charged for the call. However, it does use your mobile minutes which you have allotted to you each month via contract, so if you go over your mobile minutes due to the toll-free call, you will be charged by your cell phone provider. It is probably best if you don't call a toll-free number, like a customer service number, from your cell phone but rather a land line, as there is no minute limit on those calls.
Do Not Call Registry
While most cell phone companies block 1-800 numbers from calling their customer's cell phones, there are certain telemarketing companies that find their way around these blocks and call people on their cell phones anyway. This is why it is important for people to individually register their cell phone numbers with the Do Not Call Registry, which is provided in every state and nationally by the Federal Communications Commission. This makes it illegal for telemarketers to contact you for five years after you have registered your cell phone number from their toll-free company numbers.
Toll Free Link to Cell Phone
If you have your own toll-free 1-800 number for your business, you can link it directly to your cell phone so you can answer customer calls at any time and in any place. These toll-free numbers can be set up for a reasonably inexpensive fee per month, with free technical support and the ability to use it easily with any phone. If you set up the link yourself between this toll-free number and your cell phone, there are no rules prohibiting how many times your number can be called. However, be wary of calling others who have cell phones from that number, as it may be blocked or in violation of the national Do Not Call Registry.
