PEORIA, Ill -- Citizens Utility Board is warning consumers of a scam that could be costing you on your cell phone bill.
It's called "cramming", and third party scammers could be charging your cell phone without your cell provider's consent.
According to CUB, the number of cramming charges has nearly doubled in Illinois in the past year.
A state law prevents landline bills from being targeted, so scammers are now going after cell phones.
"The bottom line is that Illinois cell phone bills are vulnerable to fraud right now," said CUB Communications Director Jim Chilsen. "Every Illinois consumer who makes a cell should be reading their bills very carefully."
CUB has created an online "stop cramming center" for those who have been scammed.
