The U.S. Federal Communications Commission on Friday issued a four-page letter (.pdf) to Verizon's vice president of legal and external affairs demanding more information about the company's planned $350 early termination fee.
The fee, which is almost double the existing amount, will apply to "advanced devices," likely including the new Motorola Droid smartphone, RIM BlackBerry Storm2 and HTC Droid Eris.
The FCC is asking Verizon how its customers will be notified of the new ETF, how the formula is calculated for pro-rating customers who are well into their contracts, and what constitutes an "advanced device."
There are also questions about mobile Web charges for smartphone customers that do not sign up for a data plan.
The FCC has asked for answers by Dec. 17.
