I just did mine..It has to be done from the cell phone you use.. This is by the Federal Trade Commission.
Hey guys this can save you a headache... pass this on...
Cell phone numbers going public tomorrow
REMINDER....all cell phone numbers are being released to telemarketing companies tomorrow and you will start to receive sale calls.
.YOU WILL BE CHARGED FOR THESE CALLS
To prevent this, call the following number from your cell phone:
888-382-1222.
It is the National DO NOT CALL list. It will only take a minute of your time
It blocks your number for five (5) years. You must call from the cell phone number you want to have blocked. You cannot call from a different phone number.
HELP OTHERS BY PASSING THIS ON TO ALL YOUR FRIENDS.
It take about 20 seconds.
