The Federal Communications Commission on Tuesday announced a $750,000 settlement with Smart City Holdings over allegations that the Internet provider blocked access to personal Wi-Fi hotspots.

An investigation found that Smart City—which services U.S. convention centers and hotels in multiple states—barred some consumers from connecting with personal data plans if they did not pay an $80 per day access fee, the FCC said.

"It is unacceptable for any company to charge consumers exorbitant fees to access the Internet while at the same time blocking them from using their own personal Wi-Fi hotspots to access the Internet," said Travis LeBlanc, chief of the FCC's enforcement division, in a statement.
