The Federal Communications Commission on Monday determined that T-Mobile must pay a fine of $819,000 for “willfully and repeatedly” failing to comply with rules regarding hearing-aid compatible handsets. According to the FCC, the carrier violated the rules during 2009 and 2010. The Hearing Aid Compatibility Order requires each carrier to have at least 10 handsets, or 50% of all devices, that support acoustic coupling and 7 phones, or 33% of all devices, with inductive coupling. T-Mobile may reduce or negate the proposed fine by proving to the FCC that it did not violate the rule, or that it didn’t violate it as severely as the FCC alleges.
