“Slamming" is the illegal practice of switching a consumer's traditional wireline telephone company for local, local toll, or long distance service without permission. The slamming rules also prohibit unreasonable delays in the execution of an authorized switch by your local telephone company. The FCC’s rules provide a remedy if you've been slammed, discourage slamming by removing the profit and protect consumers from illegal switches. The FCC can also take action against slammers.
