Federal regulators want to lessen the “shock” that comes when some consumers open their cell phone bills. The Federal Communications Commission (FCC) intends to craft new rules requiring cell phone companies to warn customers if they’re starting to run up unusually high charges for exceeding their plan’s minutes or relying on roaming services. Wireless businesses in Europe already do this by sending out text messages to consumers. The FCC was prompted to take action on this matter after receiving hundreds of complaints from Americans about getting hit with unexpected charges and having to pay hundreds of dollars more each month.
